Time stretching is one of the effects tools available in Roxio Sound Editor that allows you to change the tempo of a musical piece, be it an instrumental or vocal track. In other words, it lets you compress or extend the duration of a clip or section of a clip with or without affecting the pitch of the audio.
Preserving audio pitch
The Time Stretching tool gives you the option to leave the audio pitch unchanged when you slow down or speed up the tempo of an audio clip. Leaving the Preserve audio pitch enabled lets you avoid such problems as the chipmunk effect when an audio clip is sped up.
