Why can blank CD’s hold the same length of music at different bitrates?
> why can a CD that can hold 80 minutes of 320 kbps not otherwise hold 200 minutes of 128 kbps? Because CD audio doesn't have a bitrate the way MP3s do. It's raw, uncompressed audio (essentially the same as a .wav file on your computer).
The Short Answer
> why can a CD that can hold 80 minutes of 320 kbps not otherwise hold 200 minutes of 128 kbps? Because CD audio doesn't have a bitrate the way MP3s do. It's raw, uncompressed audio (essentially the same as a .wav file on your computer). So both the 128 kbps mp3 and the 320 kbps mp3 will be uncompressed and converted to wav format before being written to the CD, at which point their equivalent bitrates are the same.
