How many Mb will CD standard use in stereo per minute?
Also, what does bit depth relate to?
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.....
:-? :twisted: 8) :wink:
I think it's around 1,500 kb/s
