Available for download, Blue Cat Audio AcouFiend is a plug-in that simulates the sound of acoustic feedback. If you want to get a Jimi Hendrix like, infinity sustaining searing distortion without the Marshall Stack and Woodstock’s PA system, this is the plug-in for you.

It’s also the plug-in for you if you’re interested in feedback-based sound design effects. This software offers total control over the feedback, including rise time, fall time, ampltitude changes, the harmonics you’re generating, and of course when to trigger the effect. You can also transpose the feedback to create complex harmonies, and automate or control the effect via MIDI. Limit the range of notes which can trigger feedback, and use it with chords as well as single notes.

The plug-in does all this without latency, at any sample rate, and with a clickless bypass that won’t create hiccups in the sound. This software is compatible with Mac and Windows platforms, and it will operate in AU, VST, and AAX formats.
