The bit rate of CD is calculated as follows: bit rate per second = 44.1KHZ (sampling rate) * 16 (number of encoding bits) * 2 (two-channel) = 1411.2Kbps.

If it is some music CD that uses 48KHZ sampling, the bit rate is 1536Kbps

48KHZ sampling CD: 1536Kbps/8=192K/s times 60 seconds=11520K=11.52 M1 minute data volume

1 hour=691.2M data volume

44.1KHZ sampled CD: 1411.2Kbps/8=176.4K/s times 60 seconds=10584K=10.584M1 minute data Volume

1 hour = 635.04M data volume
