The Threshold Impulse Response Library

The Threshold Impulse Response Library

The Threshold is a collection of artificial impulse responses designed for the sole purpose of obliterating sound and creating droning washes of ambient texture. Abstract, harsh, luscious and dark fantasy IRs will warp, wash, drone, drown and push your sounds beyond the pale.

  • 250 impulse responses
  • 24-bit 44.1KHz stereo WAV format
  • Compatible with any convolution plug-in that supports WAV files


All demos start with a 100% dry signal that fades out as the wet signal fades in to 100%.

Sidechaining drums to gate the convolution for a delayed distortion effect:

An orchestral section drowns in swelling ambience:

A simple bass sequence morphs into a lush, filter sweeping pad:

A lo-fi drum beat degrades into a filtered drone with hints of crunchy percussion:

Clean guitar fades into a dark pad with subtle metallic overtones:

50% of every purchase of The Threshold is donated to the National Alliance on Mental Illness. NAMI envisions a world where all people affected by mental illness live healthy, fulfilling lives supported by a community that cares.
