I accidentally recorded boths sides of a cassette transfer into one Audacity file and I figured, no problem, just copy the second half of the file, open a new file, paste in it, save each separately, Bob’s my uncle.
Even though the waveform in the copied-and-pasted-elsewhere file LOOKED perfectly normal, I could barely hear the music. It was as if someone put the sound down to “1”. But I checked every setting, and it wasn’t any of that.
Is this because I had two Audacity 2.0 windows, two separate files, open at once? Or am I just lucky hitting bugs today?
I tried working the other way afterward, i.e. deleting half of the large file, saving what was left, and of course that way the file split without any problem.
