Default Digital audio stream terms?


"DaveC" wrote in message
al.net...
I'm listening to a stream via WMP. The Get Info box says:

Bit Rate: 24 Kbps
Audio Codec: Windows Media Audio 9
20 kbps, 32kHz, mono 1-pass CBR

Can someone please clarify what the bit rate means and what the audio

codec
numbers (20 kbps & 32 KHz) mean?


I believe they mean...

20 kbps = 20,000 (or 20480?) bits per second of data
through the network into your computer for this stream.

32kHz = the (original?) sample rate implying absolute
maximum 16KHz high frequency limit (likely lower).

CBR = constant (vs. variable/dynamic) bit-rate.
