Clicking on the triangle on the panel on the left of the track provides some optiosn for the track track.

To Use (Time warping Tutorial)
- Start by choosing New Time Track from the Tracks Menu
- Change the range of time warping by clicking on the Track Pop-Down Menu and choosing Set Range (an option which only appears for Time Tracks)
The converter used will be the one(s) set up on the Quality Preferences tab of the Preferences. You can make separate choices for Realtime (playback) and High Quality (exporting), trading speed against quality.
Older computers may be incapable of playing audio in real-time that makes use of a Time Track, however you can always Export the file as a WAV and then playback the WAV file later.
- To edit the time warping, choose the envelope tool from the Control Toolbar - the same tool you use to edit amplitude envelopes in Audio Tracks. Click to create and edit control points. Drag points off the track to delete them.
The Time Track has a ruler. As you edit the warping, the ruler will warp to show you at what time playback will reach each place in the audio.
