Delta Sound Labs Fold
Wavefolding/Distortion Synthesis Plugin
Fold is a distortion synthesis audio effect plug-in that only the engineers at Delta Sound Labs could dream up.
Calling on their background in modular hardware design, the team has found a novel approach to creating warmth and distortion in software.
By using an assortment of modules in an in-series FX chain, Fold imbues input signals with harmonically rich overtones and, if pushed to the extremes, completely transforms them with a unique form of distortion.
At the heart of Fold is its wavefolding engine.
First pioneered by synth legend Don Buchla, wavefolding is the act of folding a wave back on itself after reaching a given threshold.
While this naturally produces distortion and harmonics, Fold also includes a bit crusher module to further smash the input signal.
Fold's combination of oversampling, distortion, and wavefolding results in tones that are timbrally rich on one hand, and over-the-top destroyed on the other, even with simple periodic input signals.
To tame the sound, Fold comes with an analog emulation of a resonant low-pass filter that offers more control over any unhinged results.
Each parameter is also syncable to its own LFO, each with an amount slider and may be synced to a host tempo within a DAW for more creative sound design and mixing effects.
Fold also ships with a number of professionally designed presets that showcase the versatility of its engine.
