# Play-at-Speed Toolbar

From Audacity Development Manual
Play-at-Speed Toolbar lets you Play or Loop Play audio at a slower or faster speed than normal, also affecting pitch. Slower than normal speeds can make it easier to transcribe speech or song lyrics.

You can resize the toolbar, to get more precision.

You can change the speed of playback dynamically as you play audio, if you are not doing a looped play or a cut preview. Otherwise you set the setting before pressing play.

## Play-at-Speed

Play-at-Speed Toolbar has its own Play-at-Speed button which plays (or restarts playback) at the speed set by the Play-at-Speed slider to the right.

- Play-at-Speed playback can be adjusted dynamically with the slider with playback is in progress.
- Playback can be stopped using the Stop button in Transport Toolbar or the shortcut Spacebar.
- Playback can be paused and resumed at the adjusted speed using the Pause button in Transport Toolbar or the shortcut P.

## Precise setting of the playback speed

To set a precise playback speed, double-click over the slider (or create a keyboard shortcut for "Adjust playback speed"), enter the desired speed in the box and click OK.

### Setting the playback speed using the keyboard

You can control the Play-at-Speed slider with the keyboard. Right click the Play-at-Speed slider then you can use the keyboard left and right arrow keys to change speed by 0.05x increments. Note that this temporarily removes the normal use of these arrow keys to move the cursor position during playback - this is restored as soon as you make any audio selection or audio cursor positioning.

## Loop Play-at-Speed

To Loop Play-at-Speed (play the track or selection over and over at adjusted speed until you Stop), hold down Shift while clicking the Play-at-Speed button. This causes the button image to change to Loop Play .

To stop press the Stop button in Transport Toolbar.

The standard Shift + Space shortcut for Loop Play will only play at normal speed whatever the setting on the Play-at-Speed slider, but you can set a keyboard shortcut for "Loop Play-at-Speed" in Keyboard Preferences.

## Play Cut Preview-at-Speed

To Play Cut Preview-at-Speed (play audio either side of a selection at adjusted speed to preview what deleting the selection will sound like), hold down Ctrl while clicking the Play-at-Speed button (this works on Mac too, but using ⌘ while clicking does not). This causes the button image to change to Play Cut Preview (like the green Play button but with a vertical cut through it).

The standard C shortcut for Play Cut Preview will only play at normal speed whatever the setting on the Play-at-Speed slider, but you can set a keyboard shortcut for "Play Cut Preview-at-Speed" in Keyboard Preferences.

## Shortcuts

There are no default shortcut for the various Play-at-Speed functionality, however you can set a custom keyboard shortcuts for: Play-at-Speed, Loop Play-at-Speed and Play Cut Preview-at-Speed.

You can also set keyboard shortcuts for Decrease Playback Speed and Increase Playback Speed. Each press of those shortcuts decreases or increases speed respectively by 0.03x increments. }}

Export of the audio will be at normal speed whatever the position of the Play-at-Speed slider. To export at an adjusted speed, use Change Tempo in the Effect Menu to change speed without modifying pitch. Alternatively, use either Change Speed and Pitch or a Time Track to change speed also affecting pitch.
