Impulse responses are recordings from real acoustic spaces. 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 very best sounding spaces.
The results of hundreds of these travels are included with Altiverb. Ranging from London's Wembley stadium to the ancient caves of the island of Malta and the churches, concert halls and rock studios of the cities of Paris, Amsterdam, Berlin and New York. Altiverb can apply these impulse responses to any audio recording, making the recording sound as if it was played back and recorded in these real places. Scroll down to browse through the Audio Ease library of sampled acoustics for Altiverb, the IR library.
Audio Ease keeps on recording and refining their techniques and new IRs are added regularly to Altiverb, free for all Altiverb users.

A variety of digital and analog hardware reverb units.
This legendary digital reverb from the 1980s is recorded by Aram Verwoest @ SoundStash Studio, with Georg Walt.
Georg owns several units and in the nice comforts of his modern studio we could workout how to best sample this iconic reverb.
The two echo and four default reverb programs are sampled and all low and high damping configurations at eight different reverb time lengths per program. This basically covers the entire unit and allows you to dial in any setting by choosing the right IR in Altiverb.
The DRE 2000 audio examples are recordings of the DRY input track played through the actual DRE 2000 hardware reverb at the IR recording session by Aram in SoundStash Studio.
The ALTIVERB examples are bounced tracks from a Pro Tools session in which the DRY input sends to an Aux track with the Altiverb 7 plug-in inserted and Altiverb 7 has loaded the IR of the same DRE 2000 setting.
This impulse responses set gives you all the reverb programs of one of the very first and yet still highly regarded digital reverbs, sampled in a very precise way. Providing the two stereo outputs (as separate stereo sets and as a combined quad out set) and almost all combinations of the three levers. This classic reverb is (still) heard on many records.
The EMT 250 audio examples are recordings of the DRY input track played through the actual EMT 250 hardware reverb at the IR recording session by Arjen in New York.
The ALTIVERB examples are bounced tracks from a Pro Tools session in which the DRY input sends to an Aux track with the Altiverb 7 plug-in inserted and Altiverb 7 has loaded the IR of the same EMT 250 setting.
The IM90 is a French Multi-effects unit with a wide range of reverb, delay and echo programs. On top of that it is multi-sampler and a real-time pitch shifter. This impulse responses set for Altiverb features all the reverb programs. The programs with musical focus also include a long variant (twice the original preset’s decay setting).
This has become a rare effects machine, which is a shame as it is extraordinary in almost everything it can do.
Released in 1993 this rock solid reverb sits in almost every live-rack for over decades now.
The IR set includes the favorite presets like Big Snare and Bamboo room.
With its 44.1 kHz sampling rate and 20bit depth this unit sounds surprisingly clean.
Even though this unit dates from 1982 it is still used a lot today, praised for its rich or natural sound. It is loved by many award winning engineers. Zach McNees sampled quite some different decay lengths for all programs and for the Stereo Room also a low diffusion set. The Hi Density Plate and Plate Reverb are both unique. And because of modern convolution techniques all samples lack the noise you typically get from this box.
The specific unit Zach McNees sampled is owned by Matthew Marinelli at Exile Recording/Coral Sound.
The SP2016 audio examples are recordings of the DRY input track played through the actual SP2016 hardware reverb at the IR recording session by Zach McNees.
The ALTIVERB examples are bounced tracks from a Pro Tools session in which the DRY input sends to an Aux track with the Altiverb 7 plug-in inserted and Altiverb 7 has loaded the IR of the same SP2016 preset.
Audio Ease proudly shares the Grampian Spring IR from Dan FitzGerald. This set features the original (mono) Grampian Ambiophonic Unit Type 666 and also Dan's modified stereo double set of 666's called the SoundSound Spring (SSSpring).
Dan FitzGerald about the Grampian Ambiophonic Unit Type 666 and the SSSpring:
"Legendary UK Producer Joe Meek and guitarist Pete Townsend used the same spring tank (from the Hammond tonewheel organs) but now with BBC designed electronics. This ingenious circuitry had very high drive current capability, using an output stage commonly seen in car radios. but limited by a simple bulb in series with the drive coil. As the bulb lights, resistance increases dramatically. Limiting and Overload warning. Curiously Green. The extremely quiet recovery circuit would give modern Class A Mic Preamps a run for their money. The devices were manufactured for the BBC by Grampian Reproducers, a U.K. manufacturer of a diverse range of professional audio products. From Microphones to Vinyl Disc Cutting heads. There were different versions of the Grampian. Pete Townsend’s version strangely could run on batteries and included a balanced mic input. The strangeness or perhaps psychotropicicity continued with the naming of another version, The Grampian Ambiophonic Unit Type 666. This variation apparently was used in Local Radio Studios by the BBC as an affordable substitute for the EMT140 Plate. I first heard this device at concerts mixed by one of the earliest live sound engineers, Nicky Ryan. He mixed live and produced records for Clannad and later Enya, which continues to this day. Decent digital reverb had not appeared at that time so this was really the only affordable game in town. Another live engineer friend Mairead O’ Reilly and I both acquired 666’s. We noticed that the sound of the two used together, dual mono, causes a very wide spacious effect. So we built a copy of the Grampian, with an external PSU and a various other refinements. Let’s call it the SoundSound Spring. SSSpring for short.
This SSSpring had an external Power Supply which eliminated all hum. But like the original its outputs were strong enough to drive a loudspeaker. Quiet clean and powerful. This was widely used by us when live mixing much of the top action on the Irish music scene in the 70’s through 90’s. Courtesy of Altiverb we hope to have now shared and immortalized this sound in tribute to the inventors who came up with this wonderful ‘hit’ sound, and those designers who later included it in their own creations."
The DN780 is a digital reverb processor from 1985. Martin Dubka sampled all factory-set acoustic simulations presets (and some of the effects too). He later sold the DN780 as the IRs turned out to be spot on. This built like a tank eighties digital reverb offers more then Non-lin.
Stairway to heaven , We are the champions, Relax, Stir it Up, Slave to the Rhythm, Do They Know it's Christmas, There's quite a legacy to this studio. founded by Chris Blackwell, now owned by Trevor Horn.
This is one of those rare places that has produced records in everyone's collection. Samples were made of the spacious, open sounding live room, known from the Live Aid video. Our own set of mics were used, but also the 'gods' a set of 4 permanently fitted microphones were used. The tight and completely original studio 2 where most of Marley was recorded, the contained, modern studio 3, three functioning plate reverbs, the classic stairwell used on so many productions as an echo chamber, and Bob Marley's huge bathtub, which should be able to hold 1000 litres of water. Nobody dares to fill it up these days, in fear of it coming crashing through the ceiling of studio 1.
Jochem van Grieken writes: "An experiment with extremely long spring reverbs. For this one I suspended 100 meters of 3.5mm galvanized steel in a long hallway. Audio Ease's initial reaction was 'oh my god: Yes'. And after we heard the output of this monster we thought: 'oh my god: Yes'. Recorded with 4 DPA 4006's for clarity and 4 Piezo's for the sounds in the wire.
Analogue delay at its best. This piece of hardware combines a spring reverb and a long tape loop and gives you full control to craft anything from rockabilly slapback to strange noises. Pink Floyd, Radiohead, David Bowie, Lee "scratch" Perry, King Tubby, Sonic Youth and Portishead all tamed the RE-201 in their own way.
The spring has been sampled separately. From all 11 modes short and long samples are made with three different "Rates": Lo, Med and Hi, resulting in over 65 impulse responses.
Some RESO samples have been added also. These are self oscillating loops with a lengths up to 30 seconds.
The Space Echo is a mono reverb unit, the IR's are available in both mono and stereo (double mono) out. The IR contains a bit of the dry direct sound. It is recommended to mute the direct sound in Altiverb when you want to mix the effect. This Space Echo unit was kindly lent to Audio Ease by Manuel Cooymans, DJC Recordings.
The Ibanez (Sony) SDR 1000+ Stereo Digital Reverb is a full fx machine from the late 1980's. We have sampled only the reverb programs, as an impulse response of a chorus or auto panner does not work. This reverb unit was sampled at Studio Le Roy in Amsterdam (engineer: Aram Verwoest).
Dave Huizing sampled this one for all Altiverb users. Only the reverb presets are present as most chorus effects do not translate into proper impulse responses.
Clean machine, nice spring reverb. Captured by Aram @Studio Le Roy in Amsterdam.
Legendary, unique, vintage spring reverb captured by Aram & Arjen @TexAvril (Paris, France) for use Altiverb.
Fir Zuidema captured the spring reverb from this classic analogue synthesizer for use in Altiverb. Legendary.
Back to the ‘80’s with this hardware reverb. The REV 7 was an entry level ‘PRO’ reverb and was released in 1985.
The REV7 comes with 30 presets which cover various size halls, simulations of mechanical reverb devices, simulations of recording studio type acoustic environments, stereo delays, and a range of modulation type effects. The latest are of course not included in this IR set.
Although the REV7 has stereo Inputs and Outputs the reverberation is a mono sum of the left and right Inputs.
This is the full set of factory presets form the legendary L224 XL digital reverberator. While many of these machines worldwide are deteriorating beyond repair, and parts are hard to get, we have spend a couple of days with a model that worked just fine. All presets are sampled in mono and stereo including their pre-delay.
Theoretically some time-variant processes in the L224 prevent a faithful sample for convolution reverb, but in practice we have come extremely close.
This was one of the first gated reverb units and was released by Advanced Music Systems, Burnley, England. The RMX is a non-linear reverb. It has one of the all-time trademark reverb presets, Non Lin 2.
"The RMX16 is the Holy Grail of digital audio equipment. This The RMX16 would edge its name in music history on Phil Collins seminal recording In The Air Tonight. Collins later professed that the record could not have been made without the unit. The unit also allowed Prince to achieve the backward reverb baseline on the song, Kiss. Other high profile artists to utilise the unique sound of the RMX16 included Peter Gabriel, The Hollies, The Thompson Twins, and Culture Club." - AMS-NEVE
This amazing user submitted IR set contains five (5!) sampled pieces of Lo-Fi Sprig Reverb Gear by Joe Gore. This is what Joe has to say about this special set:
There are IR's from some of my favorite lo-fi spring reverbs. Three are from guitar amps, and two are cheap rack-mounted spring units. All IR's were made via sine sweep into the front end of the unit (i.e. not just the reverb section), and then recorded back into Pro Tools in stereo with a pair of AKG414s.
My personal fave is the Baldwin Professional, a horrid late-'60s solid-state amp with a reverb so cakey and think, it taints everything it touches. I've used this one on records by Tom Waits, PJ Harvey, the Eels, Tracy Chapman and others (Willie Nelson is, for some unaccountable reason, a longtime devotee of this awful amp).
The Magnatone 'verbs are also cakey, but much darker and warmer. (Magnatone was a small California manufacturer of the '50s and '60s. Magnatone users have included Buddy Holly, Pops Staples, and Lonnie Mack).
The silverface Fender Super Reverb is bright and splashy -- your classic guitar spring 'verb. (Contrary to conventional wisdom, I prefer the sound of this particular amp to most pre-CBS blackface Supers I've encountered).
The Tubeworks Real Tube reverb is a surprisingly rich-sounding spring box.
The Furman RV-1 tone is nasty, brutish and long.

Chapman Recording is fortunate to have 3 EMT plate reverbs. These acoustic devises were made in Germany during the late 1950's and offer the finest "Vocal" reverb available. EMT Plate 1 was originally owned by American Studios in Memphis and was used on several early Elvis recordings. Plates 2 and 3 were once owned by producer Phil Ramone while at A & R Studios in New York. These units can be heard on many of the Aretha Franklin and Simon & Garfunkel hits of the 1960's. All 3 plates reside in the downstairs "Plate Room" and are remoteable to control room B & C.

This one was originally part of thr Arts & Sciences building IR set (Utrecht Conservatory), but since that set hase been split up and scatterd all over the place, here it is on its own: a long (17 seconds) impulse response of a Bösendorfer Piano. Great for all kinds of sound design!
Wendy Carlos writes about her beloved plate:
"Welcome to the wonderful world of EMT 140st Plate Reverberation. As a gift to the industry, I'm making available gratis these samples of my near mint 140st, vintage early 1971. It was added to my studio when Rachel Elkind and I expanded it into the lower floor of her Manhattan brownstone. I'd become familiar with earlier versions in graduate school, as Vladimir Ussachevsky used one in the Columbia University Electronic Music Center, where I was a student of his. This model is the epitome of electromechanical design, with extremely low noise solid state electronics replacing earlier troublesome tube circuits."
Some of the top producers on the planet consider this the only option for vocal verb. Classic equipment, recorded by Rainer Oleak and post produced by Kai Hoffmann
This (out-of-production) classic unit cannot be captured faithfully using convolution reverb because it is not time invariant: it uses chorussing. The presets that use chorussing heavily will sound different than what you may expect. However 90 % of these samples are pretty much indistinguishable from the original preset. This set offers all reverb presets with original names.
This classic spring reverb was sampled at three decay settings. Mono in, stereo out.
Doesn't get any better than this. You need a mac G4 to emulate this sophisticated piece of analog reverb equipment. Mono to stereo (go figure).
Accompanying Erik Hawkins' Altiverb review in Mix magazine, here are the BX10 spring reverb samples made by Erik and depicted proud owner Victor Owens.
Eric Rehl submitted marvelous samples of these two classic Bring-Me-To-Your-Leader type echo toys.

In the audio post category are many domestic spaces like: bedrooms, living rooms, kitchens, hallways, stairwells, halls but also complete castles and museums.
Then there are cars, trains, airplanes, helicopters, factory halls, tunnels, forests, streets, fields and acoustic marvels like gasholders and a huge steel cilinder on a pipe-laying-vessel. Scroll down to see all these wonders.
A ferocious thunder falls down on you when you make some noise in this very impressive former German gas tank. We sampled these acoustics and you can now shout, play some drums or do whatever you like in this insane space.
The Gasometer Oberhausen is a former gas holder in Oberhausen, Germany, which has been converted into an exhibition space. It has hosted several large scale exhibitions, including two by Christo and Jeanne-Claude. The Gasometer is an industrial landmark, and an anchor point of the European Route of Industrial Heritage and the Industrial Heritage Trail. It was built in the 1920s, but largely reconstructed after World War II.
A subway tunnel under construction. No tracks are in here yet, so every angle looks identical. Very pretty, and a heavy, deep, satisfying reverb. Just run some low passed noise into it with the direct sound switched off for a nice and deep room tone.
This former gas holder in Sneek has the longest reverb time that we have found so far (2013). Being in there and counting over 10 seconds of reverb to whispers was probably the most stunning experience in our career as reverb hunters.
Peter Steinbach kindly shared the IR recordings he did in Alcatraz for all Altiverb users. Peter recorded three depths in the main cell block and some perspectives from the solitary confinement cell. He recorded using DPA 4006 omni mics and a Genelec 1031a speaker on a Deva 4 recorder.
Bob Schwenkler recorded this IR set and kindly asked us to share it with you.
This set is recorded with a Schoeps CMC64 microphone pair in a modified spaced configuration. Angled apart at about 90 degrees and spaced about 1.75 feet at a height of about 6 inches. The mic configuration was looking upward rather then sideways.
Environmental Aesthetics about the Satsop cooling tower:
In the late 1970's, the U.S. was more than 20 years into its nuclear power program. In Washington, a consortium of public utilities began what was to be the largest single nuclear power project in the country's history. Five reactors, divided between sites located near the cities of Hanford and Satsop, were intended to be a solution to projected energy demands of the rapidly growing region. Three years and several billion dollars into the endeavor, the remaining members of the Washington Public Power Supply System ceased construction of the nearly completed plants. Poor oversight, material miscalculations and the turning of public opinion with regards to nuclear power left the agency with no other option than to cut its losses, leaving the massive remnants of their futurist daydreaming to rest against the backdrop of rural Washington.
Today, a collection of warehouses and businesses occupy the buildings that were intended to house the administrative offices and support facilities of the Satsop plant. The cooling towers still loom over the industrial park. The towers, No. 4 and No. 5, are identical in appearance, both measuring 420 feet across at the base, and rising to a height of nearly 500 feet. No. 5, however, was never fully completed and remains free of the concrete and steel inner-structures of its twin. At its apex, the tower is open to the sky, leaving its interior exposed to the rains of the Pacific Northwest. Never having been used, the earthen floor of the tower has become overgrown with wild grasses, while the inner walls and support columns are now tinted green from the lichens and mosses that grow in the concrete's cracks and pores. The tower resembles the neck of an hourglass, tapering gradually from the base then widening again after reaching its narrowest point 400 feet above the ground. The design, meant to channel super-heated steam from the reactor's cooling system into the sky, has a similar, though unintended effect on sound. Within the tower, even the slightest sonic trigger becomes a dynamic acoustic event. Waveforms collide with the structure's walls, echoing throughout the space and unfolding in the air overhead.
The Rotterdamsche Droogdok Maatschappij (RDM), was a shipbuilding and
repair company in Rotterdam (The Netherlands) from 1902 to 1996.
This large industrial factory hall has been recorded with 4 DPA 4006 omni
microphones and the sine sweep has been played back through a powered
Genelec 1037 monitor.
A former shipyard on the northern banks of the IJ and larger than 10 football fields, the NDSM wharf is now a center for underground culture in Amsterdam. This huge area contains the NDSM hall, a hangar-like structure 20,000 sq. meters in area and 20 meters in height, and two historic ship slipways(Hellingen) housing workshops and artists’ studios.
The NDSM wharf offers facilities for a number of artistic disciplines and small crafts. The wharf has also become a sanctuary for individual artists and craftspeople as well as for independent organizations, both established and less known, to cooperate, inspire and create.
This set has been recorded using the PA installation for sine sweep playback
and two DPA 4006 omni microphones, a metric halo mobile i/o interface on
an apple laptop.
The Gashouder (Gasometer), built in 1903, is the most characteristic building in the Westergasfabriek and leaves an unforgettable impression on all visitors. The enormous cast iron ceiling construction is breathtaking and regularly used as a backdrop for film and photo shoots.
Until the 1960’s gas produced from coles was stored in this container.
We went here in June 2010 because there was a Holland Festival concert series in this structure, that, for BluRay production, needed some audio post production with original reverb.
Setup: Genelec 1037 and 4 DPA 4006's mounted on the spider.
This is one of the two tunnels, under the Amsterdam Central Station, that will connect city transportation busses to the new underground tube station. We were lucky to get in this tunnel at this stage (the construction was not completely finished yet). The 120 meters long tunnel sounds very clear and much richer then one might expect. In fact, give it a try on some music piece, it will sound different, but it could very well suit your needs. We used the 4 DPA 4006 mics for recording and the Genelec 1037 with a microtrack2 to play back the sine sweep signals.
On the evening of june 12, Aram and Arjen departed for Schiedam harbour 561, for the Merwede built Rigid reeled pipe laying vessel “Seven Oceans”, owned by Subsea 7 of Aberdeen. A pipe laying vessel winds 45 cm diameter pipe made of 3 cm thick steel on a reel and drops it to the bottom of the ocean, typically between offshore oil rigs and the continent. This reel, the largest of its kind at date of recording, can hold 17 km of this type of pipe, and Audio Ease went to sample the core of it.
It is an acoustic marvel really, perhaps of limited use to you, the audio producer. With over 20 seconds of reverb across the widest part of the frequency range one can softly whistle or sing an arpeggiated chord and listen to the sustaining chord washing away for over 15 seconds afterwards. The sweep was played back through a Tannoy reveal speaker, and recorded using DPA miniature omni capsules (DPA 4090). Apart from the sweep recording, some IR's were added that were made by exciting the hull of the reel's core directly.
The Cistern is a 2 million gallon underground water storage tank located in Fort Worden State Park, Port Townsend WA U.S.A.. Made by the U.S. Army of concrete in 1907, it is located on top of a hill in the park. Its original purpose was fire suppression and backup water supply.
It is about 150 feet diameter and 14 feet high with 88 columns supporting the roof and a steel ladder in a small opening for access. There is no near source of AC power so all recording and lighting is by battery power. Access is difficult to obtain as the Cistern is closed by dragging a pair of very large steel tanks over the opening with a backhoe when not in use to keep vandals out and lessen liability concerns over the 14' ladder and air quality issues. Access is limited to about 3 uses per year.
Neville Pearsall says: "It is an acoustic wonder and has one of the best long reverb responses in the world with a time of more than 40 seconds. The low frequency characteristics are spectacular and very pleasing. If two people are on opposite sides and place their ears near the wall you can talk very quietly and hear each other; like the whispering gallery."
The Utrecht Maliebaan Station, a train station from the 19th century, has completely been renovated to its original state from the year 1874.
First and second class waiting rooms, a luxurous dinner hall and even toilets in 19th century style work like a time-traveling portal: taking you 2 centuries back in history.
The royal waiting room from 1892 origins from the State Railways from The Hague (The Netherlands) and have been transported to Utrecht and built in the Maliebaan train station to complete it.
Recorded using a Tannoy Reveal monitor Speaker, a Sony car radio, 4 DPA omni directional microphones and a powerbook with Digital Performer and the Metric Halo Mobile I/O audio interface.
Gozo Channel Line provides a vital "Life Line" between the islands of Malta, the mainland, and Gozo. Its modern fleet includes three state of the art ferries. This is the smallest: M.V. Ta' Pinu (delivered March 2000). Samples were made of the empty loading deck using 4 DPA 4006 mics and a DynAudio monitor to play back the sweeps.
Bij de Leij is a beautiful old fashioned stainless steel tank factory in the north of the Netherlands. The Impulse Responses were made simply by banging steel with hammers and mallets. We felt very much ’in charge’ walking around in a place like this, authorized to smash whatever we preferred.
This warehouse situated in the middle of Rotterdam, in one of the most beautiful parts of the ‘old city’.
Captured between two rivers in the old harbor. This venue has been used as warehouse and also as exposition room. The place is like a parking garage, lots of concrete & pillars and large size spaces, as big as the entire floor. We sampled a big and a smaller room on the 2nd floor of this fantastic building.
