I just saw this suggested video on youtube from the channel AP mastering. I shouldn't be surprised as he put out another video where he was highly critical of some of ASR's highest rated speakers and saying that one of those terrible single driver monitors are great while ignoring multi-tone performance.
This time, he seems to have an axe to grind with the legendary Monty Montgomery video and how it has rightly been used to defend digital audio. His biggest gotcha's are kind of ridiculous and it appears that he just parrots the texas instrument's marketing material for hi-res DACs and ADCs.
Amplitude above and below the 0 line (1 out of 65,536 and the negative): That's -90dBfs. OK, not a big deal unless you plan to set your gain to +80dB on an incredibly quiet recording.
Another is that quantization error and aliasing exists, therefore delta sigma/oversampling with slow or no filters are the magic cure. While he's technically correct, he fails to quantify how insignificant this quantization error is. 16/44.1 without dither is good for -98dB or 0.00126% THD without dither and -120dB@3KHz with a modern shaped dither.
The funny thing is, most audio ADC's have a noise floor right at this 100dB mark and each track has a summing of this ambient and hardware related noise floor. This noise summing is far more significant than the influence of quantization error generated by 16/44.1. I do still believe that in the music producing world, there is certainly some value in 24/48K tracks, especially trying to keep that noise floor summing down. But, the final master can be 16/44.1K without any audible loss in quality.
