A true powerhouse of audio warfare, Grind puts the "damage" in Audio Damage. From subtle tube-style saturation to full-on mangled wavetable distortion, Grind is a Swiss Army Knife of sound design. This effect consists of three main blocks: wavetable lookup, in to algorithmic saturation/distortion/, and finally to a multi-mode filter with eleven different topologies, from your favorite four-pole lowpass ladder filter, to the 18dB screaming acid, to more subtle toolbox filters like notch. Driving it all is a tempo-synced LFO for rhythmic filtering and grinding.

Grind is code-identical to our VST/AU/AAX version, and can even load its presets. Take your favorite destruction plug on the road with you in this AudioUnits v3 version. Also includes a stand-alone app.


> Input gain and gate

> Wavetable lookup distortion module with LFO modulation over 15 wavetables, and control over window size and phase. This replaces the input sample with one chosen from the selected wavetable based on input level.

> Algorithmic distortion module. Apply one of eleven different distortion/saturation algorithms to the signal, for everything from subtle tube-style harmonic saturation to full sine driver craziness.

> Multi-mode filter with eleven different topologies, from popular vintage synth filters to studio carving tools. The filter frequency is an LFO modulation target, making this worth the price of admission for the filter alone.

> Tempo-synced LFO. In an AUv3 host, Grind's LFO automatically syncs to your host, and can provide rhythmic interest to virtually any track. Mod the filter, for timbral interest, or mod the wavetable, for the full Grind destructo-effect!

> A mix control rounds out this easy-to-use, yet deceptively intense effect. Add a little or add it all, Grind is a multi-effect that will bring any sound to life.

An almost perfect distortion app.

Please, developer, add an envelop for the filter!

This is a distinctive take on the old distortion/crunch effect. When a project or line need a hop in the rear, this never fails to take sounds to new heights of enthused depravity.

I have had no problems with the app regarding AU-host compatibility. It will not write your thank-you letters to grandma or cure your addictions, but it will do some pleasingly twisted things to your audio.

Grind gets my bubbling-warm recommendation.

The perfect filter/distorter

As in, where has this been all my life? The waveform feature is great... excellent flavor from this. It will do anything and everything you ever wanted a distortion or drive pedal to do and instantly. This with Dubstation and EOS2 made the bulk package a steal.

Some questions in other reviewson functionality: i use this on ipad pro, ios 11.4, with AUM as AU host.
