Recording Help

My reason for Audacity is to record drum tracks for other people remotely. My question is when someone sends me a track to record drums too, what is the process in Audacity?

Thanks in advance!

Recording a new track to go with an existing track is called “overdubbing” (or “overdub recording”).
See here in the manual: https://manual.audacityteam.org/man/tutorial_recording_multi_track_overdubs.html

Thanks, Steve. You’ve been most helpful.
