I need to convert lectures from their original 16-bit WAV and 320 kbps MP3 format down to 96kbps MP3's for audio streaming. You will get much a better sounding MP3 if the recording is mono rather than stereo. If you have a stereo track, convert it to mono before exporting. If you use Audacity 1.3.x...

Nothing "wrong" - it's just an unfortunate consequence of stretching. The way that stretching works is to cut the music in tiny pieces, space the pieces out as required (duplicating pieces as required) and merging all the bits back together again. This is most definitely not a "lossle...

"R" = Record
"SHIFT + R" (or whatever the equivalent is on Mac) = Append Record
"P" = Pause / un-pause
"Shift + Spacebar" = loop play

The "Keyboard" section of "Preferences" (from Edit menu) will show all default keyboard short-cuts.

You could try this trick: Import the original file as track 1 Import your "Instrumental version" with the vocal removed as track 2 select track 2 and do Effect > Invert. When you play both tracks together, you should have the original minus the instrumental. The result is unlikely to be p...
