Blue Cat Audio AcouFiend was developed to give musicians and producers access to the expressive qualities of acoustic feedback—commonly known as the Larsen effect—without the usual limitations of volume, space, and gear setup. Traditional feedback relies on high sound levels, close proximity to a loudspeaker, and the right physical environment, which makes it unpredictable and difficult to use in many recording or practice situations. AcouFiend solves this by offering a digital simulation that is controllable, musical, and available at any volume—even in headphone-only setups. It was designed to empower users with full control over feedback’s harmonics, dynamics, and sustain characteristics, opening the door to a more precise and creative implementation of what was once a chaotic phenomenon.
Key Highlights
Authentic Feedback Simulation – Accurately emulates acoustic feedback (Larsen effect) for any instrument, in any setting.
Play at Any Volume – Trigger rich, controlled feedback without loud amps or live speakers—even when using headphones.
Precise Harmonic Control – Choose the fundamental or specific harmonic to sustain, or transpose it for musical effects.
Fully Automatable & MIDI Ready – Trigger and shape feedback using DAW automation or external MIDI control.
Feedback On Chords or Single Notes – Works with polyphonic content for full chordal feedback and extended harmonies.
Blue Cat’s AcouFiend is an acoustic feedback simulator plug-in that can make your guitars scream, growl, or sing, even at low volume or through headphones, and it gives you total control over it!
AcouFiend simulates the acoustic feedback (a.k.a “Larsen effect”) well known to guitarists playing loud and close to their speaker… Except that here, you have total control over the effect.
You can choose when and how to trigger the feedback, on sustained notes or chords. The plug-in lets you select the main harmonic of the feedback, and you can even choose to transpose it for more creative effects.
Of course, it can be entirely automated or controlled via MIDI.
And since it is a plug-in, it is not just for guitars: create screaming synths, sustained vocal harmonies and more…
