Impulse responses (IR) are digital audio files capturing the acoustic "fingerprint" of a space or the sonic characteristics of equipment (amps/cabinets/effects/reverberation), developed primarily since the 1970s for speaker testing. By using convolution reverb, these recordings allow producers to simulate authentic spaces—from historic cathedrals to specific speaker cabinets—within a digital audio workstation (DAW).  History and Development: 1970s Origins: Impulse response testing was first developed in the 1970s to test loudspeakers, allowing for the analysis of phase inaccuracies caused by crossover, cone momentum, and resonance. Originally, physical impulses like starter pistols or balloon pops were used to trigger room reflections. This shifted toward using sine wave sweeps (20 Hz to 20 kHz) to accurately measure frequency responses.  Convolution Reverb Evolution: The technology matured with digital convolution, enabling the simulation of realistic, complex acoustics rather than simple algorithmic reverbs. One of the highlights of Convolution technology was the Sony DRE S777  hardware reverb unit which harnessed convolution to generate acoustic signatures of actual physical spaces. How Impulse Responses are Captured:  Generate Test Signal: A computer plays a "sweep" through a speaker in the desired space (e.g., a hall) or through a piece of equipment (e.g., an amp). Objectively speaking, the sweep method comes with lots of disadvantages. Ultimately, though, it yields a much higher quality impulse in contrast to the bang method. Record Response: A microphone records how the space or equipment changes the sound.  Process to IR: The recorded sound is "deconvolved" into a .wav file—the impulse response—which can then be loaded into a convolution reverb plugin or IR player to accurately reflect the frequency response.

Included with your download are 50 IR's of the highest audio/frequency accuracy and quality we've ever created. These captures range from deep aquatic tones, to completely dubbed out analogue submersion with three dimensional space like no other IR's we've ever come across. This is by far the most focused impulse library we've ever conceptualized, in virtually any sound applying even 10% of any IR in this library, will instantly add depth and space in ways we're still trying to wrap our heads around! (full pun intended) We were quite fortunate in being given access to the highly coveted Lexicon Primetime, Ursa Major & the rare vintage AMS S-DMX Effects which were used extensively in these sonic creations. Each capture started with a driven signal w/galvanized steel plate (1/64” thick/18 gauge steel similar specs to the coveted EMT's) based reverb unit, mixed at around 20% (from our friends in Detroit over @antiquemodulation) which truly comes through in these impulse designs. We understand and adore that genuine analogue tone and compared to most reverb plug-ins, these captures have a three-dimensional holographic sound that has to be heard to be believed. It's like swimming in an analogue ocean where the only sonic limitation is your imagination! Whether you're designing ambient soundscapes, processing dialogue, or adding spatial depth to musical elements, these IR's provide the sonic foundation for creating immersive audio experiences that transcend any digital algorithm.

100 X Impulse Responses captured at Detroit’s abandoned Packard plant, St. Agnes Catholic Church and East Grand Methodist Church conducted over the course of 3 years of audio experiments.

Using impulse responses, you can apply the acoustic characteristics of a particular location to your recordings as if it had been recorded right on location. This project was the result of 2 years of recordings conducted in various abandoned locations in Detroit, Michigan, USA.

Captured using: 2 X DPA 4006C Omnidirectional Microphone (courtesy of University Of Michigan audio/visual department) Impulse responses were (various mic placements) captured utilizing a swept sine method (logarithmic) Post processing was conducted on the final IR's in this library to enhance dimension and space, EQ curves were kept intact to preserve the ghostly harmonics of each location.
