Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. An overdrive pedal is softclipping, which is easily describes as the clipping that creates harmonic overtones. It also provides a smoother, more musical sounding distortion that retains more punch.

Analogtodigital converters adcs are obviously mixedsignal devices, but sometimes engineers whose experience is primarily with analog circuits seem to forget about their digital nature. Softclipping can best be thought of as the clipping that produces harmonic overtones. Unlike hard clipping where waves are completely squared off, with soft clipping the waves are more rounded to create a smooth transition between the clipped and unclipped sections of the waveform. Soft clipping may simply be left on at all times to reduce the likelihood of audible distortion from excessive volume settings.
