CatStretch is a 6-voice polyphonic time-stretching sample playback instrument. It lets you ‘freeze’ a sonic character at a specified position and play it back chromatically with MIDI notes. The position of a sample can be adjusted with the ‘Scrub’ dial. It uses a phase vocoder to achieve time stretching up to total time freeze.
The phase vocoder is a tool used to perform time-stretching and pitch-shifting on recorded sounds. Its name derives from the early “vocoders” (contraction from “voice encoder”), which used a set of bandpass filters in parallel over many frequency bands, to crudely analyze and reconstruct speech. The infamous hardware vocoders of the 1960s and 1970s were based on this technology, and allowed the spectrum of one sound to be controlled by that of another, e.g. a voice. Pitch-correcting software like Auto-Tune, by now widely used in commercial music production, is based on the phase vocoder principle.
