About 1.2 Mbits/sec for video, 0.3 Mbits/sec for audio
(Uncompressed CD audio is 44,100 samples/sec * 16 bits/sample * 2 channels > 1.4 Mbits/sec)
Compression factor ranging from 2.7 to 24.
With Compression rate 6:1 (16 bits stereo sampled at 48 KHz is reduced
to 256 kbits/sec) and optimal listening conditions, expert listeners could
not distinguish between coded and original audio clips.
MPEG audio supports sampling frequencies of 32, 44.1 and 48 KHz.
Supports one or two audio channels in one of the four modes:
Monophonic - single audio channel
Dual-monophonic - two independent channels (similar to stereo)
Stereo - for stereo channels that share bits, but not using
Joint-stereo - takes advantage of the correlations between stereo
