The other thing that can do this is an editing setting that forces Audacity to always edit at the zero crossing points. That can, under certain circumstances, produce audio to the left of zero -- "before it happened."

I'm searching and can't find that setting....

There's lots of reasons for Vocal Removal to fail. If the original music is mono instead of stereo, they will all fail.

Audacity doesn't save sound files. To get an MP3 file, you have to Export one and that's the tool that needs lame. If you downloaded lame and installed it already, it may just be there.

I installed the fully featured QuickTime 7 as a Utility and use that for everything. Do you have Finder set to show you al...

You'll need to fill in a few more holes. We can't be there to see what you're doing. "I connected my something-something vinyl player to my MacBook Pro with the USB cable. I changed Audacity 1.3.13 drop-down menus to recognize the player..... That's the kind of detail we need. I would stop usin...

It literally comes up through the Windows login screens like you just turned it on? Is this a homemade machine? Are you trying to run Audacity over a network? We should probably wait for the heavy Windows elves for this one, but I would be running the Windows Memory Test. Causing the operating syste...

Yeah. Change Tempo.

In Audacity 1.3, the Change tools may work a little better. I think Change Tempo may do it. One of them tries to change the presentation speed without affecting the pitch.

If you have a highly compressed MP3 song, that may be as good as it gets. MP3 compression has damage of its own and can cause problems with Vocal Removal.
