Impulse Response Libraries

The Threshold Impulse Response Library

The Threshold

The Threshold is a collection of 250 artificial impulse responses designed to obliterate sound and create droning washes of ambient texture. These abstract, harsh, luscious and dark fantasy IRs will warp, wash, drone, drown and push your sounds beyond the pale.

The Threshold II Impulse Response Library

The Threshold II

The Threshold II adds 225 more audio-demolishing artificial impulse responses for creating sonic experiences that range from harsh and metallic to lush and atmospheric. Push your sound even further beyond the pale with IRs designed to stretch and smear into oblivion, or pulse and crunch percussively.

Unnatural Spaces Impulse Response Library

Unnatural Spaces

Unnatural Spaces is a library of 40 impulse responses captured from human-made spaces, generally consisting of small objects that you normally would not, or could not, stick your head inside. These impulse responses are designed to impart unique reverb characteristics to your audio.

Acoustic Arenas

Acoustic Arenas is a found sound project focused on capturing the aural architecture that surrounds us in our modern world. Urban cacophony; natural sounds; architectural ambience; auditory snippets of life in situ: captured in stereo for your sonic explorations.

Eurorack Modules

Thunderdome

Two sounds enter. One sound leaves. That’s the basic concept of this module. Built around a DG419 analog switch, the Thunderdome uses an internal square-wave oscillator to switch between two input signals at audio rate, producing sounds ranging from atonal and metallic, to rhythmic and musical.

Ambivalence Drive

Make up your mind, already. Ambivalence Drive is here to help. Ambivalence Drive uses control voltage to switch between two input signals, routing to a single output. Use the toggle to choose between a constant 5v reference or a variable voltage set with the Voltage Range knob.

Destructo Disc

Named after the Mighty Krillin’s unstoppable sawblade of doom, the Destructo Disc is a sawtooth oscillator gone mad. Two waveshapers and an array of 555-based saw-width modulators transform a basic sawtooth waveform into a vast array of aggro sounds.

Wocka

This module is a little fuzzy. Bears are fuzzy. My favorite bear is Fozzie the Bear. Fozzie sounds like fuzzy. Fozzie likes to tell bad jokes and celebrate his bad jokes with his trademark saying “Wocka wocka wocka”.

And that’s why this module is call Wocka.

Borrowing heavily from a circuit attributed to the mysterious “R. Lockhart Jr.”, this diode/transistor-based fuzz distortion is a wave destroyer.

Inferno

How far down does the inferno go? Well… Ours isn’t as deep as Dante’s, but seven levels is still pretty deep.

Inferno is a frequency divider that creates square wave outputs at 1, 2, 3, 4, 5, 6 and 7 octaves below the original input signal.

Sprung

Sprung is the result of several failed attempts to track down a decent schematic to drive a Mod™ 8EB2C1B spring reverb tank. This design incorporates overdrive and feedback circuits, to provide a very basic module to drive this specific tank.

Adverb

Adverb is a stereo reverb with individual control over depth and mix for each stereo channel. Mono or stereo input (mono input normalizes to both channels).

More information

Lil’ Verb

Lil’ Verb is a mono reverb module with dual outputs, and feedback control over both outputs.

Wah Baby

Based on a classic wah pedal design, fitted for Eurorack. Includes CV control over the effect switchable between an external CV source or an internal LFO.

SSSCM

The next time someone tells you math isn’t magical, introduce them to the Single Sideband-Suppressing Carrier Modulator–or SSSCM for short.

More information

Forked

Conceptually based on the DivKid/Instruo Ochd (but with four LFOs instead of eight–get it?), Forked is a free-roaming modulation workhorse, with triangle and square outputs. One rate knob sets the general speed for each LFO, all of which run independently and asynchronously from one another.

Steptone & Son

Steptone & Son is based on the Stepped-tone Generator designed by Forrest M. Mims III. Also known as the Atari Punk Console, this is a classic DIY noise-maker comprised of two 555 timer-based square oscillators. Our version adds some new features to make it more flexible for use in modular systems.

4Square

4Square is a nasty little box of fun built around a 4093 quad NAND Schmitt Trigger circuit. Four independent square-wave oscillators pinging off of one another to create complex sounds–metallic FM sounds, stepped square waves, classic video game bleeps and bloops.
