splitting tracks

Hi, I have a capture of a stereo recording and I want to do an edit only on the left track. I there a way to spit the stereo track to do this?

Yes, you can either split the track into separate left and right channels, or split to two mono tracks. Click on the name of the track (at the top of the info box on the left end of the track) to select the commands. See: http://manual.audacityteam.org/o/man/audio_track_dropdown_menu.html
