Let's break this down first. We need to understand our bandwidth and dynamic range requirements. What is it that humans can and cannot detect? As in not resolve into music, but simply perceive as a mechanical vibrations of air. Do we have a consensus on what these requirements are?

  Summarizing point? no longer a reason for 16/44 as the ultimate distribution format for consumers.   To answer your first two questions we would need assign a metric to the digital audio performance captured vs a given format. Personally, I am not aware of a generally accepted metric that...

  In the context of this thread, this video may be interpreted too literally and one may conclude that based on the experiments that bit depths and sample rates shown are more than sufficient. Consequently, those continue to argue that conclusions in this video is gospel.   Or put it another...

        Amazing how the fundamentals slip out your head after some time.  You guys more or less covered it for me. Something along the lines of a certain class of energy signals that fall into category of power signals which can still be analyzed using fourier integration without blowing...

  It's been a little while for me so my math may be a bit rusty and I may need some help with this.  If we let x(t)=sin(2π ft), which is a real signal and plug it into the definition for finite total energy of a signal, which is given by: That doesn't look like E < inf. Anything I am missing?

  Is that Kirk Hammett? Of Metallica?

    That's not right. I only recommended a few chapters not the whole thing.  Besides, I talk to you in prose and you talk back to me in slang. Some conversation!

  My stereo now only receives hi-rez.

  Hmmm. Not up to audiophile standard just yet. Maybe after some burn-in frequency response will change to handle >20KHz.

  There is plenty of content beyond 20KHz. It just falls off ... eventually.

  Well I guess he's not going to post on this forum anytime soon then.

  Luckily high frequency content tends to falls off. And I am not talking about your sound system reproducing gamma rays. But yeah, point taken.
