IR1A Convolver


IR1A Convolver is a convolution plugin that let you apply the sonic characteristics of one sound to another in real time, using an impulse response file.

It features a high quality, zero latency convolution engine, capable of reproducing everything from guitar cabinets to lush natural reverbs and special effects. IR length can be set, along with high or low pass filtering, and predelay for creative sound shaping.

The integrated file browser makes it easy to navigate and load IR files including importing external files. It loads standard mono or stereo AIFF or WAV format impulse response files, and comes with a starter library of presets.
