and has better quality than CDs.
What media files are you listening to? I know there's some lossless files out there that are taken from a better-than-CD master, but for the most part even "high quality" files are a lossy format, usually 320 KbPS MP3, which may or may not be indistinguishable from a CD (speaking perceptually; fidelity is definitely lost, the question is whether a human being is capable of noticing), but will most definitely not be better than said CD.
It might just be my older CDs or crappy disc drive I have but the tracks I've ripped off them seem to be a lower bitrate (128kbps) than the MP3s that I download (320kbps). However it is near to impossible to hear whatever differences there may be through my speakers/headphones so I'm probably just talking out of my ass.
Okay, I see what you're getting at. What's going on is the default setting in whatever program you're using to rip the CDs is set to 128 K; I know Windows Media Player is like that. There should be an option somewhere to kick it up to 320, maybe even something to put it in a lossless format depending on what program you use.
When you rip a CD, you're not making an exact copy, you're compressing it down to a smaller, usually lower quality format. I'm not sure what the exact bitrate of a 1X[footnote]The speed at which an audio CD plays[/footnote] CD is, but I know it's in the megabits, not the kilobits. It also uses a completely different format to store the music, called Pulse Code Modulation (PCM) which is essentially a gigantic digitized version of the sound wave. Basically Mp3 is to PCM as a zip file is to a word document, except that unlike a Zip file, an MP3 can't reconstruct all of the data, only the stuff that the computer thinks humans can hear.
To give an idea, a basic (90 minute) CD holds about 750 megabytes of data. A 60 minute mp3 is usually (although it depends on the bitrate) about 30 megabytes. I wish I could give an exact comparison with a 90 minute mp3, but I've never actually come across one that big.
