Let me hit that again. Interference Rejection depends on the two sides of the balanced line to be actually balanced. The start and stop impedances don't matter, although I attended a lecture by the Jensen Transformer people who make a good case for maximum trash rejection when the destination is hig...

<<<The input impedance on the two inputs should be matched as closely as possible for maximum CMR (common-mode rejection).>>> I don't know that I agree. Common Mode Rejection is a function of the current match between the two sides of the balanced line. Impedances are irrelivant, but they are requir...

The AUP file and the /DATA folder (and contents) may not be enough. If the original show used someone else's sound files, then all those files need to come over as well -- and in their original folders. This is why we tell people they can't move Projects. If you have a complex show, you may have fil...

True differential is the only configuration that will reject electrical interference on the microphone cable. Noise arrives single ended and the microphone signal arrives differential. If both the microphone and the noise are single ended, that's the end of the show -- there's no way to get rid of t...

Goodness. There are no limits to the complexity we can generate with a question like that. I picture a nice sound mixer with monitoring and four microphones, etc. However, before I start throwing part numbers, does your laptop have a built-in microphone? Have you ever used it to record anything? Doe...

It doesn't have to be filtering damage. You're suffering from straight sample damage. Digital sampling has to be at least 2 times the tone you're trying to reproduce. I use the older number of 2.6. To sample a 5000 Hz tone with unquestioned accuracy requires a 13000 Hz sampling frequency. Barely ade...

You missed the whole front part of the question. "I'm playing a Gibson #3 guitar and singing into a Sennheiser 665 microphone connected to an Arts Dual Pre USB adapter connected to my Philips Voyager laptop." Correct any of that that isn't right. I'm assuming you're trying a live capture -...

<<<Using additional software or a loopback connector are also options on Windows 7.>>>

Unless you're on a laptop then it's a good deal more of a problem.

<<<For the price of a decent iMac you could probably buy two Toshibas>>>

The Mini was $600.

<<<I'm sorry if I am not giving you enough info,>>>

We'll ask you if we need more.

Record a fresh short hummy voice or open an existing one with hum on it and Export As WAV. Close Audacity and open that WAV file up in Windows Media. Still hummy?
