Playback Speed Dialog

This dialog allows you to specify the playback speed of the active audio file and all clips of the active audio montage.

  • To open the Playback Speed dialog, right-click Playback Speed on the transport bar, and select Edit Playback Speed.

Presets

Allows you to enter a name to save the settings as a preset and select them from the Playback Speed pop-up menu later.

Speed Factor

Sets the playback speed as a percentage of the normal speed.

Time Stretching

Compared to the speed coefficient, this is the inverse, a deceleration coefficient. This value is equivalent to the percentage found in the Time Stretching dialog.

Keep Constant Pitch (Pure Time Stretching)

If this option is activated, the pitch of the audio is not affected if the speed is changed.

Quality

Allows you to select a quality. The Best Quality and High Quality modes provide the highest quality, but are also the most CPU intensive. In most cases, the Standard Quality is sufficient.

Acceleration by Skipping Low Level Regions

If this option is activated, regions of the audio that are below the threshold level are skipped during playback.

Level Detection Sensitivity

Determines the sensitivity of the level detection analysis.

Level under Which Audio Is Skipped

Determines the threshold level for a region to be skipped during playback.

Bypass Effects and Master Section

If this option is activated, all active effects in the audio montage and all global effects in the Master Section are bypassed. This saves processing power and usually the plug-ins are not needed trying to locate audio material.

Bypass Audio Meters

If this option is activated, all meters are bypassed to save processing power.

Note

Changing the playback speed does not change the original audio, but only the playback speed in WaveLab Pro.
