http://groups.google.com/group/comp....e79f473?hl=en& : 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 |
