Time Stretching

Time stretching is an operation that allows you to change the length of a recording without affecting its pitch.

With time stretching, you can make audio material longer or shorter. This function is most often used to match the duration of an audio section with other material. You select the material to be stretched and use the options in the Time Stretching dialog to find a stretch factor. You can specify the length or the tempo, according to what the situation requires.
