Cool. Or cooler than you think. You have a laptop that can switch successfully between a microphone type of connection and a high-level Line-In. There is a trick to doing what you did. Launch Audacity and once it arrives, click once anywhere inside the red record meters. They should wake up and star...

Pretend I'm going shopping and I need to buy exactly what you have and connect it up the same way. What do I buy and connect?

Without knowing any more than that, I'd say your sound files are at 44100 KHz sample frequency, so far so good, but 32 bit floating, not 16 bit fixed. iTunes will have no idea what to do with that. I would be using QuickTime Pro to convert them, but I don't know how to deal if you don't have QuickTi...

<<<Those and the ground wire are hard wired to the TT so I can't replace them.>>> I'd be surprised if that was where the error is. I suspect the Turntable internal power supply is leaking some raw building power into the sound connections. That's why your whole system becomes unstable if you reverse...

Plug the FireWire back in and turn it on--let it regotiate. Launch Apple > System Preferences and make sure the right audio output device is selected. Launch...

Funny you should say that.

Yes.

The easy answer is to blow up the timeline waveforms with the magnifier tool. A "real" stereo signal has left and right wiggles in the waveform that very clearly don't match. Two Track Mono will have identical waves. The compulsive will want to split the stereo track, invert one track and ...
