## What is WaveFolder?

WaveFolder is a simple Wave Folding Audio Unit Extension. 

Wave Folding is an interesting distortion effect that adds harmonics to the original signal by folding the waveform back on itself when it exceeds a clipping threshold. 

WaveFolder is great for adding spice to monophonic synth leads and rhythmic, tempo based modulations can turn drum loops into totally new entities, while long, slow, free running modulations are perfect for dirty ambient drones. 

WaveFolder lets you set the folding thresholds and modulate the folding amount and symmetry with tempo based or free running modulators. WaveFolder also includes a wave shaper to add even more interest. 

There is also a short built-in manual and a selection of colour themes.

### 5/5 — This AUv3 is mental.

*2020-02-27*

Buy it. 

I own pretty much 90% of the AUv3 effects out there and this has become an instant favorite. The level of modulation that this little tool will grant you will have you revisiting EVERY AUv3 you love. 

This little guy is really one of my favorite effects out there, comparable to Eventide’s level of greatness but at 33% the cost, what else do you need? 

This is a beast.

 Thank you

### 4/5 — Good effect app...

*2019-02-22, version 1.0.5*

Once you get a hang of it. Never crashed on me and I’ve been using for a while now.

### 1/5 — Garbage

*2018-02-01, version 1.02*

Totally unstable. Crashes DAW.

### 5/5 — Add Grit to Audio

*2017-11-11*

An app that allows you to add grit and punch to your audio tracks. It’s straightforward and can be dialed in to adjust the level and shape of the wave folding you desire.
