I have a reel to reel tape I transferred to digital. I didn’t realize there was a track on the “back side” until the tape was destroyed thus the I have the “forward” in the left channel and the flip side is in the right. Can I reverse the right channel and then make both their own forward recording?
Since you have said that the tape is broken, I would add to make a copy of the original capture BEFORE doing anything since you can’t do it again if it goes wrong.
