I have several recordings of myself playing solo piano. They were originally recorded to cassette and later digitized.
One of the stereo channels is consistently and significantly quieter than the other channel.
I’ve read the Wiki article on amplification and normaliztion and know how to normalize the channels so that the peak level on each channel is the same. What I’d like to do, however, is to correct most of the discrepancy between the two channels but to leave some of it. (The mic for the louder channel was slightly closer to the bass end of the piano, although both mics were equidistant from the piano as a whole.)
Is there a way to increase the volume of the quieter channel but not to bring it all the way up to the volume of the quieter channel? (If there is no way to do this, I’ll normalize the channels independently so that they have the same peak level.)
I use Audacity under Windows 7 and XP.
