Trimming a track in a multitrack project

Navigate to the Edit view in your project, and swipe up to expand the track stack to display previously recorded tracks, and note which track you want to trim.

Tap on that track number or name in the track selector strip to open the dropdown menu, then choose "Adjust Track Trim". Drag either end of the track to trim as needed. Then, if you’d like to trim another track, just tap on the additional track to select it and then adjust its beginning and end trim points.

Once completed, select Done and expand the track stack view again to see that your track or tracks were trimmed successfully.
