Gol Gumbaz
 

Gol Gumbaz
Bijapur, India

"If you walk into the place the internal size of it is humbling, but you soon forget because you'll be taken by the acoustics as soon as you start making sound.

Tubes
18 different pipes, tubes and hoses

Burglary via air conditioning vents, sewer pipe escapes, talking through pipes in prison, Pokemon jumping through garbage chutes, there is definitely a need for the acoustics of tubes hoses and pipes in the movies. So we recorded 18 of them, small to very large, plastic, concrete and steel, for your post production and sound design convenience.

World's longest reverb: Underground diesel storage tank
Inchindown, Scotland, UK

In search of the longest reverb in the world we landed on the edge of Kinrive Forest in Scotland, where hidden in the side of Kinrive Hill, are two bolted doorways.
The doorways lead to the bombproof fuel tanks of Inchindown, one of three secret fuel stores constructed near the main naval anchorages in Britain, in this case Invergordon naval base. The British government needed to keep stores of fuel, in case the German Navy managed to block the ports or destroy shipping convoys and stop fuel supplies reaching Britain from overseas.

As part of an 2020 Apple TV+ documentary film production (featuring Mark Ronson) about reverb, Audio Ease recorded the 9 meter wide, 237 meter long and 13.5 meter high tank, which indeed holds by far the longest reverb Audio Ease has ever come across.

The tank is constructed from concrete which sits against the hard rock of Kinrive Hill. The only access for humans is through an 18 inch pipe. We recorded inside using 6 microphone stands with DPA 4006's and the largest Genelec that would fit through the hole in the entrance pipes, the 1032 monitor.

RAF aircraft hangar
Bentwaters park, UK

This aircaft hangar was used by the Royal Air Force (RAF) during the Second World War, and by the United States Air Force (USAF) during the Cold War, being the primary home for the 81st Fighter Wing. The structure of this hardened hanger is a dome of solid concrete. It has an exceptionally long and deep reverb. Recorded using a genelec 1037 and 6 DPA 4006 Omnidirectional microphones.

Gasometer
Oberhausen, Germany

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.

Subway tunnel
Noordzuidlijn, Amsterdam

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.

Gas holder
Sneek, The Netherlands

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.

Alcatraz prison
San Francisco Bay, California, USA

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.

Satsop cooling tower

microphones and the sine sweep has been played back through a powered
Genelec 1037 monitor.

NDSM Warehouse
Amsterdam, The Netherlands

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.

Westergasfabriek
former gas holder, Amsterdam

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.

Bus tunnel
Amsterdam, The Netherlands

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.

Gigantic steel reel
Subsea7, Seven Oceans

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
Forth Worden, WA, USA

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."

Train station
Utrecht, The Netherlands

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.

Ferry

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.

Steel tank factory
Bij de Leij, The Netherlands

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.

Las Palmas warehouse
Rotterdam, The Netherlands

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.

Flood tunnel
Utrecht, The Netherlands

Underground flood tunnel in the city Utrecht, The Netherlands. This 120 meter (400 ft) long concrete underground tunnel in the center of the city is not accessible for public. During a transitioning phase of re-opening part of the formerly closed canals in the city we had the chance of getting into this tunnel and sampling it for your pleasure. This place is concrete all over, great for choirs, low frequency synth drones, new age pads or sound effects.
