I sing in a barbershop quartet & chorus. We use recordings of a quartet to practice our songs. The recordings are in stereo, with my part on one speaker and the other three parts on the other speaker, so my part is louder than the others when the speakers are balanced. When I think I have the song learned, I use the following sequence to adjust the balance, so that my part is silenced:
Hardware & Sound
Speakers (default device)
Drag left speaker to zero volume
I've managed to create a desktop icon for "Sound", eliminating the first two steps, but I still have to do the rest, and it's cumbersome. Is there any way to automate more of this process?
