Select Monophonic for processing monophonic sounds (such as a vocal melody).

Select Polyphonic for processing complex sounds (such as a multipart musical selection).

Select Rhythmic for processing percussive sounds (such as a mix or drum loop).

Rhythmic mode uses transient analysis for time shifting. If you select audio with no apparent transients, or set the Transient Threshold control to a setting above any detected transients, Time Shift assumes a “virtual-transient” every three seconds to be able to process the file. Consequently, the file should be 20 bpm or higher (one beat every three seconds) to achieve desirable results. For material that has no apparent transients, use Monophonic or Polyphonic mode.

Select Varispeed to link time and pitch change for tape-like pitch and speed change effects, and post production workflows.
