I have a very distracting, annoying tone, squeal, high pitched frequency in the songs I am recording from my vinyl albums to my computer. Annoying because sometimes I am the only one who can hear it! Of the people I have had here at the house to listen to it, only a couple actually heard it, but had no idea of where it could have come from. The audio is otherwise fine, but being the perfectionist that I am, I have to find the source of this noise. I have swapped all the cables going from the stereo preamp to the computer sound input and actually the sound is not present as I monitor the recording via headphones attached to the stereo. So I think it is coming from within the computer itself. BTW the computer in question is a Pentium 4 running Windows XP, and has built-in sound on the motherboard. I would like to move this operation to my PC case converted beige G3 with the WIngs A/V card, but have not found any OS 9.x software which will do what Wave Corrector does on the PC. All helpful suggestions very much appreciated!
I don't know about the source of your sound though - the only time I've had really high pitched (i.e. above what most people seem to be able to hear) noises from the PC it's been a failing PSU and a failing HD.
I'm not familiar with Wave Corrector, but it might be worth recording on the Beige and then editing on the PC. It's sound hardware is leagues ahead of most PC onboard sound, although there are exceptions (Nvidia Soundstorm and the VIA Envy24 chipset spring to mind).
Audacity is a good free audio editor for Mac - it's a little idiosyncratic but very powerful. I converted a whole bunch of vinyl a few years ago, and I've left all the clicks and whatnot in. The problem is that the sort of algorithms used for click removal also take out a load of other stuff too. The only post processing I did was high pass filtering at 16KHz (to remove noise - vinyl doesn't do a good job of reproducing frequencies above this anyway) and low pass at 20Hz (to help eliminate rumble).
