Remove all the envelope control points from a track
For some tracks with very discrete signal patterns (like a drum machine), Audacity will automatically apply control points to the track. It can be very time-consuming to delete all of those control points, so here's how to delete all of the control points for a track at once:
1. Select the entire track. Select Edit|Copy or Ctrl-C to copy the track to the clipboard.
2. Select File|New to open another instance of Audacity.
3. Select Tracks|Add New|Audio Track.
4: Select Edit|Paste or Ctrl-V.
5: Select Project|Quick Mix (version 1.2) or Tracks|Mix and Render (version 1.3). Audacity will render the track without control points.
6. Select the new track. Select Edit|Copy or Ctrl-C to copy the track to the clipboard.
7: Return to the other instance of Audacity with your open project.
8: Select Tracks|Add New|Audio Track.
9: Select the new track.
10. Select Edit|Copy or Ctrl-C to copy the audio from the clipboard to the new track. Your project now has two versions of the track: the old track with the control points and a new version of the track with no control points.
