My technical skills are wanting and I am unable to articulate this answer in a more numerical manner, so I am hopeful Bren will be able to step in and take this to it's next level. I have been reading his posts with some interest and he has displayed a technical expertise that, I believe, we should all strive to emulate.
For my own sanity, I'm going to assume there was no sarcasm in that. Audio and video (and especially compression schemes) are subjects I've got more than just a passing interest in. I was enraptured by the idea of digital audio when I first realized that using my C64 to poll a 0820ADC a few thousand times a second would give me a digitized audio stream, a lot of trial and error after that gave me the fundamentals.
a 50%-50% mix of two digital audio signals is
(samp1+samp2)/2 - just an average... that blew my (13 year old) mind
Started playing with ways to compress video images shortly after that... was all just a hobby... then 10 years later, it becomes a part of my job.
Every teen should have a friend with an electrical engineer father with an oscilloscope!
