In that case you have a number of different comporession algorithms you can use, but you are essentially throwing away data to approximate what the original signal looked like. The more data you throw away, the poorer the sound. There are plenty of sophisticated tricks that you can play but lossy compression is lossy compression. AAC is Apples compressions scheme, and it sound better than MP3. There are other compression algorithms out there, and they tend to get better as we get more computing horsepower.

I was with you up until the last part...which I disagree with. Although a cd is certainly limited to 44.1khz (signal compression), as far as I know, there are no data compression techniques performed on cds that conform to 'red book' standards. In other words, the amount of storage consumed on the cds is essentially the same as the raw .wav file (i.e. no data compression). I'm not trying to argue...just curious that maybe I'm missing something.
