Indeed, the nature of the fourier transform is what allows for the signal to be perfectly reconstructed in theory for frequencies below Nyquist.
More practically, it's not only filtering but also the slewing nature of both the analog part of a DAC as well as the physical speakers themselves.
I only brought this up specifically because I've seen more than a few times in "Analog is better" articles the 'stair step' representation of a jagged digital waveform, which is itself total nonsense.
- camtarn 4y agoI'm very familiar with the basic details of the Fourier Transform, Nyquist Theorem, etc etc. I was taught how to build a DAC from discrete components in University, and I've read up on the multiple types of DAC. And I still disagree over this minor point of wording - I still don't think it makes any sense. But honestly, it really doesn't matter. You clearly know what you're talking about, wording or not, and I understand your argument and think it's sound, so no further nitpicking from me :)
