which factor shows the music quality?!!!
Is that only bitrate or sample rating?

[Oreo]

Yes, pretty much. Music quality is determined by the Bit Rate, i.e 64kbps is low quality 300+ is good. The sampling rate, i.e. 96khz is high. And the Bit Depth, 24Bits are used on modern Sound Cards, 16 Bits on lower quality ones.

Atleast thats what i think, your music might sound bad if its been played through bad quality speakers or sound card.

Crysalis or EricB are the ones to listen to though, they should be able to clear things up.

Remember CD's are 16bit stereo - 44.1kHz.
If your soundcard outputs in 24bit your golden. Higher resolution discs are coming soon, the 16bit pcm cd standard may no longer be. Having a soundcard that does 24bit is good for future formats. (HD DVD, Blue-ray)

Kbps will vary between format.
An mp3 at 320kbps, will sound excellent and very close to CD standard. Mp3 has a very good compression ratio, a smaller sized file with good quality playback.

Now a regular CD that is not compressed (wav) has a bitrate of 1411kbps. There is no compression involved so it has to move/stream alot more data per second.
