The original convolution reverb

Altiverb is a plug-in that makes your audio sound as if it was played back somewhere else, adding the acoustics of existing spaces to your own recordings or to your live audio. All spaces in Altiverb were recorded in the real world, from Sydney Opera House to a Scottish underground oil tank the size of a cathedral.

Altiverb impulse responses

From all over the world

Longer than anyone in the industry, and with more ear for detail, Audio Ease has been traveling the world to record the acoustics of the best sounding spaces.
The results of hundreds of these recordings are included with Altiverb 8.
Ranging from London's Wembley stadium to the ancient caves of the island of Malta and the churches, concert halls and rock studios from cities like Tokyo, Paris, Amsterdam, Berlin and New York.

The IR browser

The Impulse Response library is now more accessible then ever because of Altiverb's newly designed browser. Select impulse responses by clicking photos of rooms. Instant, gapless loading, finding similar sounding spaces, organise by reverb length (RT60), and single click favorites are just a few of the possibilities. The Impulse Response Browser and the pictures in it are resizeable and contains an extensive search field.

Classic reverb gear

Altiverb contains a tremendous amount of classic reverb gear and purpose built echo chambers. You will find all the EMT plates you want, spring reverbs, classic digital gear like the 480, 224, the RMX 16, the 250. Add the Frank Sinatra and Beach Boys echo chambers and you have everything you need to recreate all those classic sounds.

These IR sets match the real hardware units very closely, usually indistinguishable from the original,
as you can compare below, by switching in realtime between:

In all examples there was no damping applied in the 240 unit. Martyn's setting is his preferred one: the -24dB Low cut on the 240 and a personal EQ setting to boost treble. The other two examples are the -24dB low cut and no low cut. All 240 audio examples are recordings of the DRY input track played through the actual 240 Gold Plate in Martyn Heyne's Studio in Berlin at the IR recording session.
The ALTIVERB examples are bounced tracks from a Pro Tools session in which the same DRY input has the Altiverb 7 plug-in inserted on its track and this Altiverb 7 has loaded the IR of the same 240 setting.
A close listen will reveal that the IR in Altiverb lacks the noise the real 240 reference recording has.

Creating your own IRs

With the sweeps and tool you get with Altiverb 8 you can capture acoustics yourself and use these impulse responses in Altiverb. Please check the tutorial video and follow the tips to get best results.

Watch the video Follow the tips, get started

If you have any questions or need assistance in this process: contact support@audioease.com.

Sweep recording requirements

  • To make your own impulse responses (IRs) you must playback a sweep sound from a speaker.
  • You must record this with microphones, as many as you want output channels from your altierb impulse response.
  • The input recording must be an interleaved wav file with SMPTE channel ordering, so if you need a center channel it must be the third channel. Pro Tools bounces any interleaved file always in SMPTE channel order.
  • The largest alowed output configuration is 9.0.6. (note: 7.0.6 is not produced, instead 9.0.4 is produced when 13 channels are in the recording.).
  • The recording must contain either 1 sweep, including start and end blip, for mono input, or two sweeps for stereo input.

Impulse Repsonses made like this, with the Altiverb sweeps and the tool that comes with Altiverb, may only be used in Altiverb. These IRs are saved in Altiverb Proprietary format. Reverse engineering or re-sampling is prohibited. This information is also in the End User License Agreement of Altiverb.

Best practices

  • use omnidirectional microphones.
  • Space the microphones far apart, several meters if possible.
  • Carefully measure that everything is symmetrical, with large setups, a large error is easily made.
  • To test your setup on the location: play dry music through your speaker and compare the recording in the room to the dry recording. Decide if you would be satisfied if that were Altiverb.
  • You will find your speaker to be the most critical component. Few speakers when free standing like in the video, sound neutral on-axis at a couple of meters distance. Neutral is crucial if you want to reverberate dialogue and match it to something real. If you feel the result sounds too thin, try a speaker with bass reflex ports on its front, or a bigger speaker, or change out directional microphones for omnidirectional microphones. all of these measures will increase the low end in a more complex and natural way than post-eq.
  • Do not playback loud, to protect the people around you, and do not record loud to make sure you don’t clip the recording.

Features

Apart from the extensive library of impulse responses you get with this plug-in, Altiverb features some clever controls for shaping the sound of this convolution reverb.

Reverb time

Decay

This essential reverb parameter is very prominent in Altiverb 8. You can apply an exponential decay on any impulse response to reduce the reverb time, without changing the character of the room. Read more...

Over the years we have recorded in multiple rooms that allow physical reverb time control by introducing objects that dampen the room, like curtains for instance. For many rooms we sampled both wet (no damping) and the more intimate (dry) settings and added both to Altiverb. When you compare a wet setting with the right amount of reverb time reduction you will hear you get very close to the original in dry (dampened) conditions recorded impulse response. This shows how natural this control behaves.

Brightness

Brightness

Real spaces often contain less high frequency content than algorithmic (synthetic) reverbs. Sometimes you need that extra sparkling brightness in a reverb tail that is just hard to obtain from the real world. Read more...

And often this cannot be achieved with EQ, because what’s not in the signal cannot be turned up with EQ either.
This is where brightness comes in.
Brightness adds an entire algorithmic synthetic reverb on top of the real-world impulse response. It tailors the reverb tail exactly to match the IR, following length, slope and early reflections closely, so that it connects and the result does not fall apart in two sounds. By turning up brightness you dial in more of the synthetic reverb and thus more high frequencies.

Damping

Damping

Control the reverb length of three separate and adjustable frequency bands. Shortening is damping, lengthening is enhancing. You can see the effect of damping in the waterfall graph of the impulse response.

Stage positions

Stage position

Altiverb can have mono or stereo inputs. When making impulse responses, we used either one speaker position in the center of the stage for mono input, or two speaker positions for stereo input. So there is a direct relation between the amount of inputs and the speakers used. Using the positioner tab, available only in mono and stereo input Altiverbs, you can switch on the speaker, in which case you can hear where it stands. You can also, right there, move the speaker around.

This is the absolute most realistic sounding virtual playback of your audio in any space in Altiverb.

You should use it fully wet, but even then you hear quite some dry-ish material, because there is a direct path from speakers to microphones. A demo of this is in the first minutes of the Altiverb 8 guided tour video.

The four knobs on the right manipulate the different stages of the impulse response, starting with the earliest part: the direct sound. The gain and color of the direct sound can be adjusted. Color is adjusted between neutral (flat) and the actual direct sound that is in the Impulse Response (IR), which sounds more realistic, but can give unwanted coloration as it can contain a very early reflection from an on stage piano or the stage itself, and also includes speaker and microphone coloration.
Early and tail can be switched on or off and the levels can be changed too. Read more...

Stage position

An exhaustive recording session in a Viennese concert hall gave us an algorithm that allows you to accurately place your sound anywhere on stage of all our concert halls, or in any of our other rooms. Physically correct sound placement using the Altiverb Stage Positioner creates a stunningly realistic audio panorama.

Back in December 2003 Audio Ease went to several rooms to make samples using a larger than usual set of source positions. The goal was to find out what exactly the influence of stage position is on the impulse response, so an algorithm could be derived that allows the source sound to be moved around on the stage of any hall or room available in Altiverb. The following is a demo using Altiverb's resulting 'stage positions' feature for a specific case:

Creation of a convincing stereo image of a sampled orchestra on a stage
altiverb stage positions
pro tools mixer

First, listen to what the stage position control in Altiverb can do

altiverb stage positions audio demo

The percussion section is placed in three different positions on stage in the same hall (Konzerthaus, grosse saal). The image is the starting position, but then the percussion moves to the rear and then the right rear. There are two speakers on stage because the input audio is a stereo mixdown of a percussion section.

Maarten's demo

We asked Maarten Spruijt, composer, maker of primary demos for such renowned sample manufacturers as Vienna Symphonic Library, Spectrasonics and ProjectSAM, to compose a short movement for us. As his instrument he chose to use the Vienna Symphony Library of orchestral samples.

This is what his dry, un-positioned orchestra sounded like:

Instrument track inserts

We asked Maarten to distribute his separate instrument tracks over the stage using Altiverb's stage position feature. Each track was to be played back from a different position on stage.

First thing to do was insert Altiverb on each of the 15 instrument tracks. Each Altiverb loaded with the same microphone setup. A setup close to a stage was used to achieve a wide stereo image:

Vienna Konzerhaus microphone placement layout image taken from Altiverb
The Vienna Konzerthaus 10m, omni directional mics

To ease the load on the CPU, and to remain more flexible, the choice was made to not render the full tail in all instrument tracks. Instead all 15 Altiverb instances in the instrument tracks only use the direct sound and the early refs (reflections).

tail off

On the master track, one Altiverb will take take care of the tail. This way the longest part over the reverb is applied once instead of 15 times and by using this setup you can easily change the tail sound.

Selecting Instrument Positions

Then the Altiverbs were switched to their Stage positions tabs. The direct gain control now becomes disabled, as the Stage positions control takes over the gain of the direct sound.
Stage positions were selected, by dragging the speaker for mono instrument tracks, or by dragging both speakers for placement of stereo mixdowns of instrument groups.
Classic orchestral positions were selected, with percussion in the far back of the stage.

Listen to Maarten's tracks carefully positioned

Maarten's positionings are available as Altiverb plug-in presets here:
Orchestral positioning presets

A single master Altiverb for the reverb tail

With all of the instruments placed properly a final Altiverb was put in the master channel to take care of the reverb tail. Mechanics Hall in Worcester MA was selected to provide the reverb tail. The instrument tracks now provided the direct sound and early refs in the production, so the direct sound of the master Altiverb was set all the way down, as well as some of its early reflections (early).

av7-no-direct-low-early-tail

With the master now only rendering the tail, the mix between the placement and the tail could be made using the wet/dry control of the master Altiverb.

Check out this final result. A very convincing orchestral stage, that could not have been achieved using traditional panning.

EQ

Equalizer

Altiverb features a four band equalizer. The bass and treble bands are Baxandall EQs, designed to not shift phase more than 180 degrees, which effectively means that combing or cancellation effects are unlikely when the EQ’d signal is mixed with the dry signal. The equalizer works on the wet signal only.

Reverb size control

Size

Makes the selected room (impulse response) smaller or larger. This transposes room modes and resonances, tightens or spreads early reflections, and shortens or lengthens the reverb tail.

Microphone

Pre-delay

Delays the onset of the reverb. If the note symbol is clicked, the timing of the delay is locked to the tempo of the host application so you can select an eighth-note as the delay time.

Cloud Size and Pan Tracking Reverb - from LCR up to 9.1.6 input Altiverbs

Stage position

Altiverb XL supports more than two inputs. With more then two inputs there is no longer a direct relation between an input and a speaker that was used when making the impulse response. Therefore the Positioner tab is unavailable. Instead there is a new control: cloud size. With cloud size turned down, the reverb no longer outputs to all output channels, it starts clustering around the input pan position of your sounds. Even when the input sound moves, the reverb cloud travels along with it. The Altiverb 8 guided tour video gives an example of input pan following reverb starting at 5:43.

Microphone

Attack

Fades-in the start of the impulse response, resulting in a more lush, distant reverb sound.

Reverse

Reverse

The entire impulse response is reversed in time for backward reverb effects.

Modulation

Modulation

This effect does not emulate anything that happens in reality, it emulates something that happens in artificial reverb algorithms. Read more...

When the impulse response is modulated, the frequencies of input notes are a little bit spread out. The effect is that a note that is a bit off-key (false) does not necessarily remain false in the reverb, or that the reverb may sound a bit more full, or that a snare sample that is input twice to Altiverb does not come out of Altiverb the same way twice.

Gated reverb

Gated Reverb

Allows you to abruptly cut-off a reverb after a set amount of time. The gate time can also be locked to the tempo of the host application.

Mixer

Mixer

Everything is recorded with enough microphones to provide Atmos reverb (up to nine eye level speakers plus six over head channels).

There's a new output meter and a mixer that provides full control of all outputs.

Snapshots

Snapshots

Snapshots are presets that are private to an instance of Altiverb. Read more...

Another Altiverb in the same session contains different snapshots. Snapshots are saved in the session/project. Snapshots can be switched using automation. The automation preset index parameter does that. Snapshots are an inheritance of older versions of Altiverb and no longer a necessity in Altiverb 8 because Altiverb 8 is a total-recall plug-in, meaning that the entire state of the plug-in can be automated without the use of snapshots.

note 1:

Levels are improved in Backward compatibility situations for the Altiverb 7 instances with input-output: quad to quad, 5.0 to 5.0 and 5.1 to 5.1.

Altiverb is a music and post reverb. The 5.0-in 5.0-out Altiverb, however is mainly targeting post. The 5.0-in 5.0-out Altiverb 8 loads new true 5.0 IRs by default, implements easy center-channel-only reverb with input pan following and adjustable cloud size. For Post this instance has undergone massive improvements and it was the most challenging to keep it backward compatible.

In a 5.0 input to 5.0 output instance of Altiverb 7 a stereo to quad output IR was loaded by default, mainly because no 5.0 IRs existed in Altiverb 7. Center reverb was created via the center bleed option, a delayed mix of the rear channels in the front. Altiverb 8 will load the IR that was chosen in Altiverb 7, including the center bleed. You may, as we do, prefer the native Altiverb 8 way: if you have just upgraded to v8 when opening your Altiverb 7 project or template we advise you to open your Altiverb 5.0 input to 5.0 output instances and load the true 5.0 Impulse Response in there. One should be available for most Impulse Responses in the Altiverb collection.

When cloud size is increased it gradually adds speakers which increases the total level. Cloud size did not exist in Altiverb 7. In Altiverb 8 5.0 input to 5.0 output Altiverb 7 settings are loaded with 60% cloud size, which may result in a higher output level than in Altiverb 7 produced, depending on different circumstances.

Similar measures have been taken in the quad input quad output and the 5.1 input 5.1 output instances. Please note that all of the above only applies to Altiverb 7 settings received by Altiverb 8.

note 2:

Version 8.0.7 chooses a better fitting center channel for a number of rooms.

With the Stage Positioning turned On the Center channel now better equals Left and Right channels in a number of rooms.

We use widely spaced omnidirectional microphone setups to capture the IR. Left and right microphones are typically spaced by more than 3 meters. For Altiverb 8 we needed to select a center output to the front L and R microphones in every room. We originally decided to use a front row center microphone for that. However, that microphone faces the center stage speaker on-axis so it is brighter, and its path is shorter so it is louder. This can be tolerated to a peak level difference of 4dB between center and left output. However as was pointed out to us by score mixers and upon careful review, we have, in a number of rooms, now decided to use the second row center microphone as the front row center output. This results in an improvement of the balance of the collection. There are no new Impulse Response names, so no automation breaks. There are differences but they are usually slight. If you have been using the center channel in Altiverb 8 in one of the rooms below, you may hear a difference.

av7 installer damaged
Here's what you can do when the newly downloaded installer fails to run because the macOS reports the downloaded installer failing verification (or reports it is damaged and cannot be opened).
  1. Make sure you use the macOS default 'Archive Utility' to open the downloaded zip file (other utilities could corrupt the installer app while unpacking the zip file).
  2. Please check if there is a security update available for your macOS and please install this.
  3. Open Safari and check if you can visit https://www.audioease.com.
    When you can visit the website in Safari, then please retry downloading the installer. If the download fails to run, you can try using a different browser. Any of the following: Firefox, Opera, Chrome, Safari, will do.
Perhaps the download is broken, in which case a new download with another browser may work. Otherwise the solution may be to use Terminal, a built-in program on the Mac.
  1. Make sure you use the macOS default 'Archive Utility' to open the downloaded zip file (other utilities could corrupt the installer app while unpacking the zip file).
  2. In case that does not solve it, open Terminal. You can use the Mac search at the top right and start typing Terminal. It will appear, click on it to open the program.
  3. Type “unzip” and a space, then drag/drop the zip file into the Terminal window.
  4. Press Enter and the zip file will be unzipped, storing all files on your computer.

License activation

If you have just purchased an Audio Ease product and received a serial number you can register this here:
www.audioease.com/ed

Why register?
When registered you can access the downloads and immediately get licenses to activate the software.

When you have purchased your software directly at audioease.com there is no serial number. In this situation you can get your licenses directly at:
www.audioease.com/authorization
If you have just purchased at audioease.com or registered a serial number you can immediately get an iLok license for your product.

Simply go here: www.audioease.com/authorization
fill in your registered email address and proceed.
In case your iLok key is lost, stolen or broken we will help you out right away, even in case you have not invested in additional insurances or coverage at ilok.com.

Send a message to support@audioease.com and we will provide you with a 30 days expiring backup license so you can continue your work immediately. A spare iLok USB key is required for this, as the software (Altiverb, Speakerphone and Indoor) requires the ilok usb key. This means the software will not work without an ilok usb key with a license on it.

To resolve this situation permanently you may have to acquire another iLok USB key. We can help here too:
We can send you one at a not-for-our-profit-price, which will normally takes 2-6 weekdays in Europe (6-20 weekdays to the rest of the world), available at: audioease.com/store. Depending on your location purchasing locally might be quicker.
Yes, you can sell / transfer your license to another user.

If you have a license stored on an iLok key please transfer this license to the new owner by using the iLok License Manager. Please note: while PACE/ iLok fees apply, there are no fees imposed by Audio Ease.

Then please send a message to support@audioease.com with the name, email address and ilok user account info of both you and the new owner.

We will then transfer the software registration at audioease.com to the new owner, so that he/she will be able to access all downloads and (future) upgrades.
You can use the software with a single license on more then one computer. Simply connect the ilok usb key with the license on it to a computer and you can install and use the software.

However you can use the software only at one computer at a time.

When you need to run the software in two locations (two rooms / two machines) at the same time this requires two licenses. This means purchasing two copies of the software. We do not offer any second license deals or discounts.

General troubleshooting

Altiverb 8 is universal (native Apple silicon and Intel)

Indoor, Speakerphone 2 and 360pan suite 3 work fine using Rosetta 2 on the Apple silicon machines. The performance is great.

We are currently working on adding native silicon support to all plug-ins.
As soon we have news on this we will share it.

The latest BarbaBatch, Snapper and Make a Test Tone are all universal applications, supporting both Apple silicon & Intel.

Pro Tools states it is not a valid 64 bits plug-ins
Most likely the installer or the plug-in got corrupted in transit. Please download the latest updater installer on the computer you want to use it on. Then move the downloaded zip file on the desktop and there choose to extract it using the Mac OS X default Archive Utility app. Once you did this please run the updater installer from the desktop to install the correct aaxplugin and this should cure the problem.
The aax plug-in can get corrupted when transferred on some external (or network) drives. The plug-in won't validate properly then.
Authorization Wire Exception bad channel id "Speakerphone / Altiverb cannot run, because an error occurred. Encrypted Channel Bad Channel ID (or USB error or frame is an invalid size)"

Authorization Wire Exception invalid size

Errors like these can be solved by downloading and installing the latest ilok software from www.ilok.com. Altiverb, Speakerphone, Indoor and 360pan suite require this software.
Windows Authorization Error: Altiverb 7 Regular cannot run because it is corrupted please try reinstalling the product

This error means the graphics card driver on your system is not up to date. Even when Windows states this is up to date, Altiverb 7 can generate this error and you will find there is a newer driver available (and this will solve this error).

Please try to update your graphics card driver.

Find out what graphics card you have in your system (right click on your desktop, choose change screen resolution, hit advanced settings, that would show you the manufacturer"s name and the model).
Then please go to the manufacturer"s website, hit support/drivers and find the latest driver for your graphics card and download and install this.
Restart your computer.
The problem should be gone now.
The plug-in is installed correctly (Altiverb / Speakerphone / Indoor / 360pan suite) and the ilok software is up to date and still the plug-in cannot be found in Cubase (or Nuendo).

Let's clear Clear the Cubase vst preferences to force a re-scan of all vst plug-ins (in case the plug-in is blacklisted)

  • Remove all plist/xml files with VST in the file name from the Cubase preferences folder, check this post where to find the preferences folder.
  • Then restart your computer.
  • After the restart run Cubase. Cubase will now re-scan all plug-ins and it should load the plug-in again.

360pan suite

Currently the 360pan suite cannot detect the video window in Pro Tools 2023 on Windows. Until this has been resolved in an update we advice to stay on Pro Tools 2022 for 360pan suite on Windows.
When using HDX hardware the Hybrid Engine needs to be Enabled for the private (pre-fader) sends from the 360pan plug-in to the 360reverb to work.
When the Hybrid Engine is disabled the distance cannot be controlled for a panned source. The 360reverb does work as normal reverb insert/aux effect on HDX systems with disabled Hybrid Engine.
When you use the VST3 360pan suite plug-ins in Reaper you will have to verify two settings in Reaper's preferences are properly set up, else the suite will not function properly.

In Reaper choose Preferences... from the bottom of the Options menu and then first go to:

Reaper preferences - turn off Anticipative FX Processing 1. Audio -> Buffering
and then TURN OFF the Anticipative FX Processing
this will ensure the 360reverb to function properly (else you will get sync problems)

Reaper preferences - VST-parameter-automation
2. Plug-Ins -> VST
Under VST Compatibility please set the Parameter automation notification to:
Process all notifications
this will ensure automation is written to track when you control the panner pucks from the video overlay (without the panner plug-ins being open).

Reaper preferences - automation-do-not-add-points.png
3. Editing Behavior -> Automation
When recording automation and stopped should be set to: Do not add additional points.
This to ensure you can nudge the time cursor and then drag pucks and write automation this way (like in the tutorial/example project).
It could be some or all 360pan suite plug-ins are missing the first time you run Reaper after installing the 360pan suite VST3 plug-in. Reaper then needs a gentle push to see all plug-ins in the suite.

In Reaper choose Preferences... from the bottom of the Options menu and then open the VST tab in Plug-Ins:
  • Hit the Re-scan... button
  • Choose (from the popup menu) Clear cache and re-scan VST paths for all plug-ins
  • Quit and restart the Reaper app
Reaper preferences - Clear Cache and rescan to make the plug-ins appear
The video preview in the 360monitor AAX plug-in only functions (on modern systems and recent Pro Tools versions) when the Pro Tools.app is allowed to record the computer screen in the macOS system preferences.
Make sure you set this option to fully benefit from the 360pan suite plug-ins options.

360monitor video preview: Allow Screen Recording for Pro Tools
Quick start: download & check out the example project / session featuring a short 360 video of us running around at Audio Ease, mono panning audio, a true ambisonics (b-format) FX recording, binaural preview and export suggestions.

True headlocked stereo is not possible in the ambisonics audio format.
Ambisonics audio is a 3D audio sphere and headlocked (fixed) stereo sound does not fit into this.
This is simply impossible.

Headlocked mono is possible, that is the top channel only.

360pan suite offer to mix to the top channel using the position blur control.
More position blur (more mix to top) is more mono, more inhead/headlocked.
When you pan your stereo source hard left and right (-90 and +90) in the ambisonics sphere and you set the position blur to half way (somewhere between 0.40-0.60) you will find there is stereo sensation while you cannot really identify things turning when you look around in the 3D sphere.
If you move the position blur control more towards 1 you will find it will rotate less, but it will also be more mono. That is the trade off.

Altiverb 8

There will be no MAS Altiverb 8 plug-in.
Before you upgrade to Altiverb 8 please save the settings of your MAS Altiverb 7 plug-in instances in your projects as Altiverb presets (irp files). You can do this in the Altiverb IR browser.
These will be converted by the Altiverb 8 installer so you can load your settings into your Altiverb 8 Audio Unit instances when you replace them. In case in a while you need to turn back to an old project where you have not done that we can provide temporary licenses so you can do this still.
Do you have customer IRs, or did you add your own IRs, impulse responses, to Altiverb 7?
You have to copy these to the new location Altiverb 8 uses to ensure Altiverb 8 also finds these.
The new location is:
/Users/Shared/Audio Ease/Altiverb/Impulse Responses/User Created IRs

You can also verify Altiverb 8 uses this location, in the preferences tab in the plug-in: Altiverb 8 user irs prefs
Altiverb 8 is backwards compatible with Altiverb 7. when you install the upgrade license replaces your altiverb 7 license, and the Altiverb 8 plug-in will be loaded in your older sessions, sounding identical to Altiverb 7 (and Altiverb 6 and Altiverb 5).

Forward compatibility is limited: sessions made with Altiverb 8 don’t load reliably on systems with altiverb 7 installed because new functions may have been used in the Altiverb 8 session that are lacking in Altiverb 7.


Speakerphone

If Speakerphone 2 is gone after you updated Pro Tools to 2023.3 (or later) and you are on a Apple Silicon Mac (M1/M2 ARM) then you have to open Pro Tools Using Rosetta to get Speakerphone 2 working.

At this moment all Audio Ease plug-ins require Open Using Rosetta on the Apple silicon (M1/M2) macs. We are working on new versions of the plug-ins that will add native support for apple silicon. As soon as we have news on this we will let you know.
For now you need to open Pro Tools using Rosetta in order to use Speakerphone 2.
To ensure Pro Tools opens using Rosetta:
  • open the Finder
  • go to the Applications folder
  • select the Pro Tools app
  • hit get info
  • tick the box to Open Using Rosetta.
Open Pro Tools using Rosetta
By granting this directory read & write permissions for all users an admin user can enable all users on Windows to use the Speakerphone VST (or AAX) plug-in:
C:\ProgramData\Audio Ease\Speakerphone

Without setting this Speakerphone will crash when a non-admin user tries to use the plug-in.
The challenge/response hard disk authorization is only available in the older (32 bits only) Speakerphone 2.0.5.
You are free to use this one instead of the latest, the 2.0.5 installer is available from the downloads page.

We strongly discourage running this old Speakerphone 2. This version will not be updated anymore. We recommend to use the latest Speakerphone 2.1. This one does require the iLok (2nd generation or up) key yes. Whenever your ilok key breaks or you loose it, we will always help you (supply a new license for a replacement key).
Most likely the Speakerphone 2.1 installer removed the resources from an older Speakerphone 2.0.5 installation however the installer failed to remove the Speakerphone 2.0.5 RTAS plug-in. When Pro Tools 10 now loads the Speakerphone 2 RTAS you get this error message. Then later Pro Tools scans the AAX and decides not to load the RTAS anymore.

Solution:
We need to fix this in the installer of course, but when you delete the Speakerphone.dpm (the RTAS plug-in) from: /Library/Application Support/Digidesign/Plug-Ins/ this error message will be gone.

Altiverb 7

If Altiverb 7 is gone after you updated Pro Tools to 2023.3 (or later) and you are on a Apple Silicon Mac (M1/M2 ARM) then you have to open Pro Tools Using Rosetta to get Altiverb 7 working.

At this moment all Audio Ease plug-ins require Open Using Rosetta on the Apple silicon (M1/M2) macs. We are working on new versions of the plug-ins that will add native support for apple silicon. As soon as we have news on this we will let you know.
For now you need to open Pro Tools using Rosetta in order to use Altiverb 7.
To ensure Pro Tools opens using Rosetta:
  • open the Finder
  • go to the Applications folder
  • select the Pro Tools app
  • hit get info
  • tick the box to Open Using Rosetta.
Open Pro Tools using Rosetta
Problem: Non-readable text in the Altiverb 7 user interface.
Solution: Follow this guide to allow Altiverb to access the font again:
https://support.apple.com/en-gb/guide/font-book/fb34862/mac

Altiverb uses the system font Arial. Altiverb does not install this, it should be on your macOS by default. If your system does not have the Arial font or the macOS system prevents Altiverb somehow from using it, Altiverb could look like this:
Altiverb 7 font missing or blocked
Problem: Installed or updated Altiverb 7 and now it does not show up in Logic.
Solution: Restart your mac.

Somehow (we are still trying to find out why) the macOS ignores Altiverb 7 until the computer has been restarted. This is why Logic (or Ableton Live, or any other DAW that uses Audio Unit plug-ins) does not show the Altiverb
Altiverb 7 Regular and XL sound exactly the same and come with the same IRs.
There are three differences:

Altiverb 7 Regular supports
  • up to stereo input and output
  • sampling rates up to 96kHz
  • plug-in formats on windows: aax native and vst, on mac: aax native, vst, audio unit, mas and rtas
Altiverb 7 XL supports:
  • up to 5.1 surround in and output
  • sampling rates up to 384 kHz
  • all plug-ins formats Altiverb 7 Regular supports + TDM on Mac OS X

So, in short, if you do not have sessions on 192k and you work in stereo only, Altiverb 7 Regular will do just fine.
If, at a later stage, you would like to upgrade from Regular to XL this is possible. The upgrade cost is just the price difference so you won't loose any money going for Regular first.
Problem: The IR set gets downloaded when you click the download button in the NEWS section in the IR Browser. It starts downloading but then nothing happens, the set does not load or show up.

When this happens the Altiverb plug-in fails to copy/move the downloaded IR set to the Audio Ease IRs folder.
It could be Altiverb is not allowed to write in the Audio Ease IRs folder.

Solution: Try locating the folder in the finder (or explorer), hit get info and then verify your user (and the admin group) can read&write in the folder. If you make changes make sure to also apply to all enclosed items too. If this does not help, try using the default location as IRs folder:
/Users/Shared/Altiverb/IRs

You can change the IR folder location in the preferences tab in the Altiverb plug-in:

Altiverb 7 ir folder location in preferences
Altiverb 7 supports loading your own files as IRs.
Any wav audio file can be used as impulse response.

Simply add your file(s) to your User Created IRs folder, the default location is:


macos user library folder
* Please note the MacOS system hides the Library folder in your user folder. You can still open this folder through the GO menu in the Mac finder. Then hold down the option (alt) key and a link to the User Library will magically appear.

Your third party impulse responses folders, libraries can be loaded through:
/Users/Shared/Altiverb/Third Party libraries

If you have recorded the Altiverb sine sweep to create an IR, then drag your mono or stereo recordings as wave file onto the drag and drop import window in the Altiverb plug-in. You can choose to save your IR into the User Created IRs folder.

Altiverb 7 ir import
There is a little trick you need to pull off to get this to work:
  • open the add fx window in Reaper on the 6 channel track
  • then right click on the Altiverb plug-in and make sure this option is checked:
  • ☑️ inform plug-in when track channel count changes

av7 reaper surround settings

When you then insert Altiverb 7 it should become 6 in 6 out and you will be able to choose the surround IRs in the IR Browser.
Most likely you were working with old older (version 7.0/7.1) IR set before and you recently installed the latest Altiverb 7 plug-in updater. This new Altiverb 7 plug-in however requires the latest core IR set.
To fix this please download the latest first time full Altiverb 7 installer and run this.
Once you installed this you will have all IRs again.

> You can request a link to the latest downloads at:
www.audioease.com/download
Altiverb 7 Windows Authorization Error: Altiverb 7 Regular cannot run because it is corrupted please try reinstalling the product

This error means the graphics card driver on your system is not up to date. Even when Windows states this is up to date, Altiverb 7 can generate this error and you will find there is a newer driver available (and this will solve this error).

Please try to update your graphics card driver.

Find out what graphics card you have in your system (right click on your desktop, choose change screen resolution, hit advanced settings, that would show you the manufacturer’s name and the model).
Then please go to the manufacturer’s website, hit support/drivers and find the latest driver for your graphics card and download and install this.
Restart your computer.
The problem should be gone now.
There is a situation where the Altiverb plug-in can revert to default settings when loading a project in Digital Performer.

This is caused by the fact the Digital Performer (DP) supports three plug-in formats: MAS, AU (audio unit) and VST.

How?
Example: When you save a project with the Altiverb MAS plug-in. And you then change the default plug-in type in DP to AU and re-open this project. DP will load Altiverb, but DP fails to transfer the saved Altiverb MAS plug-in settings to the now Altiverb AU plug-in, and Altiverb then reverts to loading the default settings (which is the Teldex IR).

When this suddenly occurs you are most likely using a different plug-in format then you used before. Try to find out what you used before, force DP to load this Altiverb plug-in from the plug-in settings in the DP preferences and then restart DP and re-open your project. The right settings should load again then.

If you need any help with this let us know. Send us for instance a project file that will not open correctly, then we can quickly help you out.

Screensaver
What is the difference between the mono to stereo and the stereo to stereo options in a stereo out Altiverb ?

Best way to understand this is to go back with me to our sampling session when we recorded to room's acoustics for the IR in Altiverb.

mono to stereo
We put a single speaker in the center of the stage and two mics in the audience.

This results in a mono to stereo IR.
When you playback your audio through this IR in Altiverb, it will sound like your audio comes out of that single speaker from the center of the stage (mono!) picked up with two microphones (stereo!).
This IR gives a stereo reverb, however the input is (mixed to) mono, as there is only a single source on stage.

When you want to process a vocal (mono) or direct recorded electrical guitar or something where the panning is not important the mono to stereo IR will do just fine (pro: costs half of the processing then a stereo-to-stereo IR, so it is more efficient in cpu and memory).

back to recording the room
this time we put two speakers on stage, one on the left and one on the right side of the stage and we record again with the two mics in the audience.

When you playback your stereo audio through this IR in Altiverb your stereo signal comes out of these two speakers.
Easy to picture here that your original panning will be maintained using a stereo to stereo IR.

So basically it comes down to this:
is your input stereo or is it panned in stereo ?
use a stereo - stereo IR, else you will loose the stereo information in the reverb (although the reverb is stereo).

Sometimes even when using stereo panned sources a mono to stereo IR can be preferred as you do not want the panning to be reflected in the reverb levels. But this is a mixing decision which depends on taste mostly (and music style) and I dare not to advice on that :-)
We have removed some sets from the Altiverb IR library (mainly user submitted IR sets) that do not meet up to our current standards. The Speakers and Phones set is one of these. You can copy the original set from your Altiverb 6 Impulse Responses folder (if you still have this) to the Third Party IRs folder in the Altiverb 7 Impulse Responses folder.
Then you can then load these IRs again in Altiverb 7.

You can also download the original set from:

Snapper

Snapper could act weird on your macOS system. In these ways: Snapper does not (always) appear when selecting audio file or Snapper crashes on quitting the application or preferences are not recalled properly.
Some check box has to be checked in the Mac OS System Preferences to ensure Snapper works properly. Maybe this somehow did not work on your system.

Please try this:
  • first quit Snapper (make sure it is not running)
  • then delete the Snapper preferences file: com.audioease.snapper.plist. This file is the Preferences folder in the User Library. Open the Mac Finder, hit the GO menu, hold down the option (ALT) key and a link to the Library folder will appear. Go to the Preferences folder and delete the file.
  • then please restart your mac (important)
  • now run snapper
  • open the mac os system preferences
  • go to the security and privacy settings panel
  • then to the privacy tab
  • select the accessibility panel on the left
  • open the lock on the bottom left (and fill in your password) to make changes
  • if Snapper is listed here, please select it and hit the - (minus) button to remove it from the list
  • now quit and run snapper and it should be added to the list again
  • make sure the box for Snapper is ☑️ checked. If it IS already checked then please un-check and ☑️ re-check it
  • quit and start Snapper

Snapper opens when you select any file that contains audio, also video files.
This sometimes is a problem, when you want to use the space bar to quickly preview the video in the finder.
There is a simple hack for this:

Use: SHIFT + SPACE BAR to preview the video

This works, even when Snapper is showing you the audio waveform of your selected video in the finder.
Snapper uses a temp folder to write the drag export files (selections) into when you drag (a selection) out of Snapper. Somehow on your system Snapper is unable to write in this folder.

By default the drag export folder is:
/Users/Shared/Snapper

You can check in the Snapper preferences what you currently use. Open Snapper, go to the preferences, open the export tab, then close to the bottom you should find:

snapper drag export folder preference
Hit the Folder... button to change the location (we recommend this: /Users/Shared/Snapper)
When this is set, quit Snapper, then start Snapper and then check in the Snapper Preferences if this option is still set correctly.
If not, we have to reset some things, see below.**
If the folder is correctly set, then let's open the /Users/Shared folder in the Finder, select the Snapper folder, hit get info and under sharing & permissions ensure your user and the everyone group are set to Read & Write.
Hit the circle with the three dots and hit 'apply to enclosed items'.
Now dragging audio (selections) out of Snapper should work again.

** If the settings in the Snapper preferences do not stick, something's wrong.
This problem is most likely solved by removing the Snapper cache and preferences.

Open the Mac Finder, hit the GO menu, hold down the option (ALT) key and a link to the Library folder will appear. Open the Caches folder and delete these four folders: com.audioease.snapper
com.audioease.snapper.filestate
com.audioease.snapper.view
com.audioease.snapper.waveform

Go to the Preferences folder and delete this file:
com.audioease.snapper.plist

Then restart the mac (this is important, as the macOS caches the prefs).
You can request your Snapper activation code by clicking on the Lost / forgot key code link at:
https://www.audioease.com/snapper/#support
This can be handy when you lost or misplaced the key code to unlock the Snapper demo to the full version.
