Acoustics for POST

Indoor is our flagship convolution reverb for Audio Post. Indoor features unprecedented sound quality, flexibility and ease of operation, AAX DSP support, click-free automation, zipper-free motion and up to nine channels of reverb, in a single resizable window without tabs. Indoor can take your studio recordings from understated to overdone, always remaining stunningly real. So that hearing is believing.

Location location

Every room, hallway and kitchen from 10 houses and vehicles, 60 spaces sampled from every angle. Click to drop speaker and microphone in any room, or to open and close doors.

Indoor any room to any room

Any room to any room

Not only the 60 rooms have been sampled but also any-room-TO-any-room is available. Over 1000 impulse responses, everything recorded in 9 channels with a consistency and quality never before presented.

Indoor turning motion

Turning motion

The microphone system can turn, creating seamless, zipper-free and automatable motion in any surround track up to 7.0 plus Dolby Atmos, fully supporting new immersive audio requirements.

Panning motion

Or insert a 7.0 to 7.0 Indoor in a bus and pan sounds into it. Use the Spread knob to tighten the reverb around each incoming source, dynamically following its panning. That’s Input Pan Following Reverb and its zipper-free.

Zipper- and click-free

Inside is a completely new convolution engine focused on impulse response changes that are click-free, zipper-free and instant, and they cause no CPU spikes. Pre-roll for IR switches is no longer necessary and neither are multiple instances to cover up switches.

AAX DSP version

Use the AAX DSP version of Indoor to drop the CPU Load and reduce latency to a millisecond and a half. You can load 3 mono to stereo Indoors on a single chip. No Indoor uses more than 1 chip. AAX DSP is available up to 48 kHz and for up to 1-in 7-out, or up to 5-in 5-out.

9 channel AB or MS

Easily switch between the two main surround microphone systems: Baffled Omni-directionals (AB) or Mid Side (MS), or combine them to create 7.0 DTS. Add two ceiling channels (for Dolby Atmos®) to get to a total of 9 channels of real decorrelated reverb channels.

Ease and speed

There are no tabs or browser windows. The window can be resized and presets are there for super quick operation. CPU load is lower than you’d expect, and because of the zipper- and click-free instant switches you will use less instances than you are used to.

Quality & consistency

Indoor more than doubles the domestic and vehicle categories of impulse responses available so far. Everything recorded with the same top quality system, so mixing and switching acoustics is more trouble-free than ever.

The Indoor 2.0.1 for Mac changes:
Native Apple Silicon support.
VST3 plug-in.
VST3 plug-in now supports up to 7.1.2 input and output.
Doors parameter automation improved in VST3 plug-in.
Dramatically improved automation timing when using many Indoor instances.
The Indoor 1.1.0 for Mac changes:
Removed support for Avid S6 as this conflicted with plug-in automation.
AAX Pro Tools: Fixed a problem with automation parameters in 7.0.2 plug-in.
The Indoor 1.0.9 for Mac changes:
updated for macOS 12 Monterey
minimum macOS version is now 10.11 (El Capitan), on macOS 10.10 and lower Indoor 1.0.7 still works great.
The Indoor 1.0.8 for Mac and Windows changes:
Indoor now connects to server (for new version check) using https
Added Avid S6 support
The Indoor 1.0.7 for Mac and Windows changes:
Fixed a problem with AAX DSP plug-ins not replacing/opening correctly (problem introduced in version 1.0.6).
The Indoor 1.0.6 for Mac and Windows changes:
Added support for the Pro Tools HD 12.8 7.0.2 and 7.1.2 tracks (Atmos).
The previous Atmos top channel solution with the extra two channel send from the plug-in is now depricated.
The Indoor 1.0.5 for Mac and Windows changes:
Location switch fallback algorithm update:
Changing the location paramater (by selecting a different building/scene in Indoor) without changing the speaker and microphone position could lead to silly combinations such as the position 'stairs' in a car. In such cases there was an algorithm in Indoor that selected the nearest possible solution. This algorithm turned out to be dependent on the previous location and was therefore not dependable. To be exact: It worked dependable when playing forward, but not when jumping back (in time) in your session. We fixed this issue, which should have no effect on forward playing of automation.
Windows only: Under certain circumstances the front left output could mute in Indoor version 1.0.3. The 1.0.5 update addresses this issue.
The Indoor 1.0.3 for Mac and Windows changes:
Automation of doors parameter is working correct now
Previously saved doors-automation (using Indoor 1.0.1 or 1.0.2) will break.

The automation parameter Doors opened/closed, which is a single parameter for all doors together, did not operate correctly in Indoor versions 1.0.1 and 1.0.2:
when a combination of opened and closed doors was stored in automation, a different combination could be recalled.
This 1.0.3 update fixes that.
Previously saved doors-automation (using Indoor 1.0.1 or 1.0.2) will break.
All doors closed does still result in all doors closed though (lowest parameter value).
solved compatibility problems with Mac OS 10.8
solved incompatibility with some other plug-ins
The Indoor 1.0.2 for Mac and Windows changes:
Added a 7 in 9 out variant which spreads reverb to the top channels (in direct off mode).
The Indoor 1.0.1 version is the first Indoor release
initial release
