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 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 small objects. The spaces themselves are man-made and are generally of objects that you normally would not, or could not, stick your head inside while listening to music. These impulse responses are designed to impart unique reverb characteristics to your audio.

Eurorack Modules


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.
