Play Properties

Play tab in Options | Control Properties or use the Properties button in the Control window.

Use Play Properties to configure the three play buttons, set the speed for rewind and fast forward, and set the marker preview time. Play button settings are given in the table.

Play Button Settings
Setting	Image	Button function
All		Plays entire sound.
Selection		Plays region between start and finish markers (the selected part of the file).
Unselected		Plays regions outside the start and finish markers. This lets you quickly test how a cut or delete will sound without actually changing the sound. When possible, playback is confined to the region shown in the Sound window view so that the entire sound does not have to be played.
Continue		Continues playback from the current playback position and stops at the finish marker. If the position is past the finish marker, playback begins at the start marker.
Continue to end		Continues playback from the current playback position and stops at the end of the file.
View		Plays all of the sound currently shown in the Sound window view. This is useful if you zoomed in on part of the sound.
View to end		Starts playback at the left side of the sound currently shown in the Sound window view and continues playback to the end of the sound.
Finish		Plays three seconds just before the finish marker, so you can determine if that marker is in the right place without listening to the entire selection.
Intro/loop/end		This is a special playback feature that plays the sound in three sections. The beginning of the sound, outside the selection, is played first. Then the selection is played and looped. Finally the end of the sound, outside the selection, is played. Be sure to check the Loop box below to enable looping. This is useful for musical accompaniment, looped instrument samples, or testing loop points.
Loop point		Starts playback just before the finish marker and loops back to the start marker and continues playing briefly. Use this setting to test the current selection markers for smooth loop points.
Loop		If checked, it specifies the number of times playback should be repeated. A value of 1 loops playback once, so the selection is played twice. A zero value loops forever. The loop image appears over the image of a button that has looping selected.

Fast/Rewind Speed
The playback speed of the Fast Forward and Rewind buttons is controlled by these values. A value of 1.00 is normal speed. Entering a value of 3.00 for Rewind speed, for example, means the Rewind button will play the sound backwards three times faster than normal. By entering small numbers (such as 0.1) the Rewind and Fast Forward buttons will play very slowly. This is useful for finding pops or clicks, since the visuals will move slowly through the audio.

Marker preview (scrubbing)
Marker preview (scrubbing) plays a very short section of audio whenever a selection marker is moved. Preview duration specifies the amount of time to play just after the start marker or just before the finish marker. Setting the time to 0 disables previewing. Use the drop-down list to select when marker preview is triggered. By default previewing is done only when the marker is moved with the keyboard arrow keys. Select the second item to enable previewing after mouse dragging as well.
