Is it possible to alter stereo music to mono?
The score is much longer than I need; how do I shorten the playing time?
Thanks
Select the track then Tracks > Stereo Track to Mono.
Edit > Remove Audio or Labels > Delete the parts you don’t want.
Or Edit > Remove Audio or Labels > Trim Audio the part you want to keep. See http://manual.audacityteam.org/o/man/tutorial_editing_an_existing_file.html .
