Muting Seperatly

I’m new and want to do mash ups of songs, I have 2 picked out for my first one but can you mute the 2 songs seperatly in certain parts?

If by mute you mean reduce the volume see “envelope tool” here …

If by mute you mean totally silence, select the part you want to silence and press “Ctrl”+“L” keys, (undo with “Ctrl”+“Z”).

If you mean one whole track, that can be done with the MUTE button to the left of the track.
