Default Linear PCM audio: 44.1 KHz sample-rate, monaural, 22,050-bits-per-second

This makes no sense.
How can
you describe 44100
samples with a single
bit?


Well, one-bit-per-44,100-cycles is what I was originally looking for.
However, as some posters have stated, all I would hear in 1-bit-per-
cycle would resemble a square wave "tick tock". New stuff is learned
everyday.

So how about decreasing the amount of bits-per-cycle so that the bit-
rate becomes 20,000-bits-per-second? After all the human auditory
system perceives up to 20 KHz so covering the entire human audio
frequency range would require at least 20-kilobits-per-second.

In a sample rate of 44,100-cycles-per-second, this would best be done
at 1-bit-every-2-cycles. This would give a bit-rate of 22,050-bits-per-
second. That's obviously above 20kbits-per-second but only slightly.

Couldn't the bit-rate be less than the sample-rate if some information
in each sample is thrown away? Could this data-reduction be done
linearly?

With each 44,100-cycles-per-second, discard half the information, and
you get 22,050-bits-per-second. Discard 1 bit for every two cycles. I
could be incorrect though. If so, please assist me.

To all:

I have a neurological disability called Asperger's Syndrome.

I would like to give you some information about my disability. The
reason I am posting this message about Asperger's is to help avoid any
potential misunderstandings [though it's probably too late].

I have been diagnosed with Asperger's Syndrome (AS). AS is a
neurological condition that causes significant impairment in social
interactions. People with AS see the world differently and this can
often bring them in conflict with conventional ways of thinking. They
have difficulty in reading body language, and interpreting subtle
cues. In my situation, I have significant difficulty with natural
conversation, reading social cues, and maintaining eye contact. This
can lead to a great deal of misunderstanding about my intent or my
behavior. For example, I may not always know what to say in social
situations, so I may look away or may not say anything. I also may not
always respond quickly when asked direct questions, but if given time
I am able express my ideas.

On Usenet, the text-equivalent of my disability is probably noticed. I
do apologize profusely, for any inconvenience it causes.

Thank you very much in advance for your understanding, cooperation,
and assistance.


Regards,

Radium
