Uh, oh, math ... okay, I'll try. Someone correct me if I'm wrong:
320,000b/s * 1B/8b * 1KB/1024B *60s/1min = 2343.75KB/min
Right so far? Okay, but then we have the disk size versus on-disk size because hardware and software makers refuse to make things simple. So:
10GB (hardware) * 1,000,000,000B/GB (hardware) * 1KB (software)/1024B (software) = 9,765,625KB (software)
Right?
9,765,625KB/(2343.75KB/min) = 4166.67min of 320kbps MP3 stereo audio fits on a 10GB (hardware) drive.
Easy enough. ...
