Limitations

Applying time stretching to audio material can lead to a degradation in audio quality and to audible artifacts. The result depends on the source material, the particular stretch operations applied, and the selected audio algorithm preset.

As a rule of thumb, smaller changes in duration cause less degradation. However, there are additional issues one should be aware of when working with time stretching algorithms.

Note

In rare cases, editing warped audio events may cause discontinuities at the edit points. You can then try to move the edit point to a different position or bounce the audio event prior to editing.

Reverse Playback and Scrubbing

Most of the algorithms used for time stretching only support forward playback. Reverse playback or scrubbing of warped audio events can lead to recurring artifacts in playback.

Stretch Factor

Some algorithms may put limitations on the maximum degree of time stretching supported.
