Muckraker is an abstract audio distortion effect to annihilate your sound. Add a gentle fuzz to your guitar or blast your synth harmonies into brutal white noise. Use with the built-in mic or an external instrument interface, or connect to other compatible music apps such as GarageBand via Inter-App Audio or Audiobus. Map external controllers to the effect controls with learnable MIDI CC. Multitask in split screen or slide-over mode on supported iOS 9 iPads.

Easy does it: a little muckraking goes a long way!

Note: Muckraker starts out muted for a good reason. It can feedback like -- well, some very feedbacky thing. If you don't hear anything, check the mute button. (You can also now switch off the automatic muting in the iOS Settings.)

Muck Luv


I don’t know why I write a review about Muckraker because you probably already have it. But if you don’t, let me tell you you can get many great distortion guitar tones that greatly rival or even surpass all those expensive amp sim apps, all for the price of nada. Plus it loads more reliably through IAA than those before mentioned others.

Whaddya mean you haven't DL'd it yet?!


To the Dev: you may not know it but you're making a lot of musicians' lives better - noticeably - every time they fire up their host DAW and one of your free plugs is there to make their tracks better - noticeably.

Get it


AB3 update = good!

I'm not sure why no one else has come up with effects quite like these, but the fact that they are unique AND free is pretty nice.

It's FREE, what are you waiting for?
