Including 44.1kHz in the analysis is ignorant of the fact that most consumer audio equipment made in the past decade or two cannot switch its clock source and physical playback sample rate to that anymore. It's all 48kHz (or multiples of that, for snake oil) these days, starting with when Intel cemented HDA on a 24MHz clock. Playing back anything 44.1kHz just gets resampled at some point before hitting the DAC, in most cases in software.

- nayuki 2y ago> It's all 48kHz (or multiples of that, for snake oil) Oversampling can be a useful internal detail for ADCs and DACs. For example, if the digital audio stream is mathematically converted to 96 kHz with a high-quality FIR low-pass filter and then fed to a DAC, then the analog low-pass filter can have a much shallower roll-off and be more easily designed. Same goes for ADCs, where the analog filter can be simple and gentle, then digitized at 96 kHz, then downsampled digital to 48 kHz with high-quality but more computationally intensive filters. ( https://en.wikipedia.org/wiki/Oversampling https://en.wikipedia.org/wiki/Oversampling , https://en.wikipedia.org/wiki/Delta-sigma_modulation https://en.wikipedia.org/wiki/Delta-sigma_modulation , etc.) But yes, listening to or distributing audio at anything over 48 kHz is a complete waste of resources.
