How much do you want to spend? The problem with most PC sound cards is that the ADC is done inside your PC -- a _very_ bad place for analog signals to be bouncing around. If this is the route you _really_ want to take, check out pcavtech.com for stats on a bunch of popular/available sound cards. If you still want the PC solution, a better way is to get an external ADC and pipe in the digital signal to the PC. There are plenty of cards which do this -- just stay away from the Soundblaster digital (how can someone screw up a digital signal that bad...?). For instance, check out RME cards: www.rme-audio.com/english. With this option, you'll be able to store them at 24/96 as well, which will sound a lot better than transfering them to 16/44.1 for CDs. I'd say that'd be the best way to go on a reasonable budget. Also, check out the mass-market CD recorders. I'm not very versed in these, but I hear they do a decent job.
Sound Cards
I'm a very picky audiophile and was stunned by a question my wife posed to me while cleaning the basement. She pointed to my old Crown CX744 10 inch reel to reel and said why don't you get ride of that thing since you never play it anyway? All you have to do is transfer your one of a kind recordings to CD. Well she just put me into the computer sound card world with a great idea. I was informed by young students at my university that I wanted to rip music. Well all of a sudden I'm part of the MPEG III crowd. Does anyone have a suggestion as to the right sound card (and software) to take an analoge stereo source and convert it to a CDROM? I'd like full 16/44.1K sampling, not MPEG III. I don't care about CD to CD transfers.
