IR is a no-latency/low-latency, realtime, high performance signal convolver especially for creating reverb effects. Supports impulse responses with 1, 2 or 4 channels, in any soundfile format supported by libsndfile.

Developed by the author for their own needs, this plugin is released to the public in the hope that it will be useful to others, but strictly on an AS IS basis. There is ABSOLUTELY NO WARRANTY and there is NO SUPPORT. High quality bug reports and well-tested patches are nevertheless welcome. Other correspondence may be mercilessly ignored; thank you for your understanding.

Features

  • Realtime convolution of impulse responses with stereo audio
  • Supports Mono, Stereo and ‘True Stereo’ (4-channel) impulses
  • Very reasonable CPU consumption
  • Maximum impulse length: 1M samples (~22 seconds @ 48kHz)
  • Loads a large number of audio file formats
  • High quality sample rate conversion of impulse responses
  • Stretch control (via high quality SRC in one step integrated with impulse loading)
  • Pre-delay control (0-2000 ms)
  • Stereo width control of input signal & impulse response (0-150%)
  • Envelope alteration with immediate visual feedback: Attack time/percent, Envelope, Length
  • Reverse impulse response
  • Autogain: change impulses without having to adjust ‘Wet gain’
  • Impulse response visualization (linear/logarithmic scale, peak & RMS)
  • Easy interface for fast browsing and loading impulse responses
  • Free software released under the GNU GPL v2
