    How many Mb will CD standard use in stereo per minute?

    Also, what does bit depth relate to?


    Thanks!

    like a 1-1.5 mb/s maybe...

    atleast, thats what it is if I rip a cd using WMA lossless.

    16 bit, 44.1 KHz PCM audio is roughly 10 MB per minute. Calculate from there.

    Only 166kb/s? I thought it was more than that....

    Fifth circle is right it is about 10MB per minute which is why a 70 minute CD has about 700 MB of storage.

    Well, they are usually 80 mins, right?

    In that case, if you divide 700mb by 80mins it equals 8.75mb/min which is 146kb/s (rounded up). I really thought it was alot higher than that.... But I never really tried to figure it out.

    10 MB/ Min... 700 min data, 79 min (roughly) audio capacity due to error correction in data discs.

    24 bit is roughly 15 MB/min (stereo 44.1), 96K runs about 15MB/Track/Min

    24 bit stereo ends up being about a gig/hour, 24/96 about a gig every half hour.

    16-bit 44.1 kHz is 1411kbps. 8.79MB/Minute.

    I think we're getting kiloBytes (kB) and kilobits (kb) mixed up here.

    maybe.... And I think I converted slightly wrong too.

    149.33 KB/s (kilobytes)
    1194.67 kbps (kilobits)

    Thats if a kilobyte is 1024 bytes

    Now, my other calculations are right if 1 kilobyt=1000 bytes

    146 KB/s (kilobytes)
    1166.67 kbps (kilobits)


    Now I was confusing kbps with KB/s. The music I have is kbps, not KB/s. So those numbers make alot more sense.

    At least until mp3 becomes considered "standard audio". Oh gawd.....

    I think it's around 1,500 kb/s
