Playback Rate

Menu Command: Effect | Playback Rate

Changes the playback rate of the entire sound. The sound will play faster (or slower) and its pitch will be higher (or lower). Essentially, this just changes rate value shown in the status bar. To change the playback speed without changing the pitch, use Time Warp.

While the playback rate of the audio device can be controlled using the speed fader in the Control window, this effect changes the playback rate of the file itself.

Some file attributes may have a fixed sampling rate. A warning is shown in that case. An MP3 file with "Layer-3, 44100Hz, 192kbps, stereo" attributes, for example, is always saved with a 44100Hz sampling rate. You must use Save As to select attributes with the rate you want.
