Please keep out the OT crap! I had to start a new thread because some
jerks decided to post irrelevant nonsense.

how would u like to change the cell phone industry?

Digital cell phones should stop using the compression they use and
start using monaural WMA compression with a CBR of 20 kbps or less and
a sample rate of at least 44.1 KHz.

Very roughly, the current 8Kbits/sec encoding rate,
compared to your 44Kbit/sec, will only handle about 1/5th the number
of users.

Who said anything about 44Kbit/sec?

The bit-rate of my WMA CBR is 20Kbit/sec or less.

1. In its uncompressed form, the audio must have a bit-resolution of
at least 16-bit

The encoding resolution is not changed by compression. If you encode
something with 16 bit resolution, and compress it, you still have 16
bit data coming out. It's the data rate or thruput that changes with
compression.

Okay.

2. The sample-rate of the compressed and the uncompressed version of
the audio must be the same.

Not possible. If the rate in and rate out are identical, then there's
no compression happening.

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
