Blue Cat's AcouFiend - Creative Acoustic Feedback Simulator Plug-in (VST, VST3, AAX and Audio Unit)

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...

User Comments & Reviews

"I found a product that is so off-the-wall, and so fascinating, it really deserved being written about. [...] If you have an experimental bent, or just want to rock with feedback guitar, it’s well worth downloading the free trial to find out what this sucker can do. It’s impressive." - Craig Anderton - [Read full review].

"I'm always partial to software that violates the laws of physics. Acoufiend gives you authentic "stack-turned-up-to-11" feedback effects in the box—no ear-shattering amp levels required. I'm not quite sure how they do it, and of course the sustain isn't infinite, but I don't care. It works, it's cool, and you can tweak it more deeply than it might appear at first. This is a home run." - Craig Anderton - [Read full review].
