CD quality native (uncompressed) audio data rates may be calculated as follows: Sample Size - 16 bit (2 byte) data representation, Channels - 2 channels, Sampling Rate - 44,100 Samples Per Second. Therefore: One Channel - 2 bytes per sample x 44,100 samples per second = 88,200 bytes per second. Total Data Rate - 88,200 bytes per second x 2 channels = 176,400 bytes per second. Total Bit Rate - 176,400 bytes per second x 8 bits per byte = 1,411,200 bits per sample or 1.41 Mb/s (0.17 MB/s). This converts to 0.709 microseconds per bit of CD audio information transmitted.
Almost all telephone companies transmit voice signals between 300 Hz and 3100 Hz. Most consider high fidelity as the reproduction of frequencies between 20 Hz and 20 kHz without distortion. Voices are recognizable within this standard telephone frequency range. Telephone companies allow an analog telephone channel a bandwidth of roughly 4000 Hz (maximum) to work with. Higher bandwidths for digital signals are possible. This limit is about 56 kbps, although very few telephone/modem combinations ever really operate at anything near that rate. 56kbps is 7 kilobytes/sec or a bit time of 17.9 microseconds.
