To be clear, In science, a theory is the best explanation for a set of facts. It is not a guess. A scientific theory consists of one or more hypotheses that have been supported by repeated testing. Theories are one of the pinnacles of science and are widely accepted in the scientific community as being true.

Mitch is correct as many theories are inconclusive. Many theories are just educated guesses based off the facts known. There's no way we could know how dinosaurs behaved as no one has seen one in real life. We can only come up with theories based off factual data from animal behavior now. The collected data might be facts but the conclusion can't be proven as fact thus a theory.

Agreed. In science, Mitch is very, very wrong. Theories mean something very specific in the scientific realm.

Science is also supported by the 3 pillars: 1) observable 2) testable 3) repeatable. The three pillars are the foundation, theory cannot be supported without a foundation. In many science disciplines the 3 pillars have been ignored: evolution, cosmology, biology...with commercial manufacturing being the #1 science today with a foundation.

Choose one song encoded in wav, 16bit and 32bit. Open the wave file. Find the third sample. What's the number stored and way? Open the 16bit file. Find the third sample. 16bit. What is the number and why? Open the 32bit file. Find the third sample. What's the 32bit number and why? After you have the binary numbers, then explain how the two binary numbers store your favorite vocab like the dynamic range, etc. And how the two binary numbers, one 16 and the other 32 are both lossless. Not one youtube video explains any of this, so it seems they don't know what they're talking about.

Let's take a perfect analog sine wave and sample at 44,000 (44k) 1) 10hz 10 waves per second = each wave has 4400 samples 2) 100hz 100 waves per second = each wave is sampled 440 times 3) 1000hz 1000 waves per second = each wave is sampled 44 times We are now getting some very rough looking sine waves as we connect the dots with line segments just 44 times 4) 10,000hz 10,000 waves per second = each wave is sampled just 4 times. How do we shape a perfect sine wave with just 4 samples?

The filters in the D/A process are designed in such a way as to filter out all of the frequencies above Nyquist. All of those sharp (non-sine wave looking) turns you see in the waveform represent higher frequency content, which when filtered out, returns the waveform to a sine wave, just as it was when it went in. Hope this helps.

@@davoman21 Doesn't sound very accurate, it sounds processed and hopeful :) . I would think 196kh would help quite a bit??? I have also seen on analog tape recording how the perfect square wave is distorted to a sine wave at plus 10,000hertz frequencies. Maybe the accuracy above 10,000hertz is not within our current technology?

@@WildernessMusic_GentleSerene This is one of the main things to understand about the work of Harry Nyquist (among others). The principles are all sound and verifiable. Digital would not work at all if this were not true, because, as you say, there just aren't enough data points to define higher frequency waveforms even close to accurately enough. This filtering indeed takes out all of the extraneous info (higher frequencies) that shouldn't be in the waveform as it is added at A/D. I get that it is counter intuitive, but it really does work quite well. It's easy to test with a signal generator and an oscilloscope. Record a 15 kHz tone into your DAW, then play it back (ignoring your computer screen) and bring that playback tone up on an oscilloscope and compare the in to the out. They will be the same. As for the analog tape example, indeed there can be increased distortion at higher frequencies. The question is, how much do they matter to the human auditory system? If we accept that human hearing is limited to 20 kHz, and understand that the first harmonic of a 15 kHz sine wave would be at 30 kHz, then you can realize that a 15 kHz sine wave and a 15 kHz square wave would actually end up sounding the same to a human who is unable to hear that first harmonic, nor any of the subsequent ones. This, on the other hand, is difficult to test, as the audio playback system would have to be able to play these waveforms without introducing any artifacts of its own, which is a tall order.

@@davoman21 Amazing it works! Anything over 10K is certainly high, limited to hearing depending on damage/age. I don't believe there is discernable instrument identification at 15k+ but all the fine finished harmonics in this upper range defines how life like the recording is to the original. Thank you for all your help. Once I listened my first CD in 1986, I never wanted to play vinyl again, but we have those folks who will only play vinyl analog on there audiophile systems. Still trying to understand what they are hearing besides tape hiss, needle rumble, distortion and massive compression.
