We are digitising some cassette tapes using Audacity.. A batch of them
are stereo, however they have exaggerated separation of the channels
(perhaps they need normalisation?), and one channel is a microsecond
behind the other. We don't actually need stereo, amd have tried to
merge the channels into mono. But this sounds dreadful - the speech
part sounds OK, but the music is very 'echo-ie).
Another batch have delays from one channel to the other measuring in
seconds. How can we time-shift one channel to match the other one?
Thanks - Chris B.
