Uncompressed audio as stored on an audio-CD has a bit rate of 1,411.2 kbit/s, (16 bit/sample × 44100 samples/second × 2 channels / 1000 bits/kilobit), so the bitrates 128, 160 and 192 kbit/s represent compression ratios of approximately 11:1, 9:1 and 7:1 respectively.
Uncompressed audio as stored on an audio - CD has a bit rate of 1,411.2 kbit / s , ( 16 bit / sample × 44100 samples / second × 2 channels / 1000 bits / kilobit ) , so the bitrates 128 , 160 and 192 kbit / s represent compression ratios of approximately 11:1 , 9:1 and 7:1 respectively .
