Been playing with rebalance and my Neil recording from Matt Knight Arena here in Eugene.
If I tune sensitivity right, I can boost vocal and cut everything else, and end up with something like a vocal track. It gets weird in some spots...
Thinking I can run this module on a copy of the stereo tracks, edit out the weird bits, and mix it back into the original tracks, boosting the vocal.
Tried a 1 minute test, and seems promising...
