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.
