Who said anything about 44Kbit/sec?
The bit-rate of my WMA CBR is 20Kbit/sec or less.

Okay.

Yes it is possible and it is compression. The uncompressed audio is a
monaural linear PCM at 44.1-KHz-sample-rate with a 16-bit-resolution
-- this audio has a bit-rate of 705.6 kbps. The compressed audio is a
monaural CBR WMA at 44.1-KHz-sample-rate with a bit-rate of 20 kbps or
less.
Where/when is there any change in sample-rate?????????
There is definitely a change in bit-rate. However, that is totally
different from the sample-rate. Totally.
BIT-rate and SAMPLE-rate are two completely different things.
In linear PCM audio:
BIT-rate = SAMPLE-rate X bit-resolution X number of channels
Stereo has two channels. Mono has one channel.
44,100 Hz X 16-bit X 1 channel = 705,600 bps
No offense but please respond with reasonable answers & keep out the
jokes, off-topic nonsense, taunts, insults, and trivializations. I am
really interested in this.
