Good afternoon,
This is probably a very basic newbie question. I’ve imported and mp3 file which was recorded in stereo., On the display it shows the two tracks but I have no means of selecting and/or deleting one track only.
Click on the name of the track. That will open the track’s context menu. Select “Split Stereo Track” to split into two mono tracks, one panned hard left and the other hard right, or “Split to Mono” to create two mono tracks both centre panned.

Thanks, that did it.
