Like, frequency is how fast the magnitude of sound pressure changes, amplitude is how far up it goes before it goes back down, but both those numbers are just derived from one number that's going up and down over time

Failing to understand this is where a lot of audiophile woo sneaks in, like this is why "high-resolution" sound files just means files that can record higher frequency sounds, these two concepts are the same thing

This is the principle behind how a DSD file works and why it has a "bitrate of 1" -- at any given timestamp there's just a 1 or 0 telling you whether the magnitude is currently increasing or decreasing (as opposed to PCM, which directly encodes the 2D image of a waveform we look at, there's a 16 or 32 or 64 bit number telling you what the volume of sound pressure is at any given timestamp)

I don't know what DSD is, but a bitrate of 1 per ear I assume? Otherwise it would have to be mono I suppose. Wait, actually even with that I don't see how a decent result could be produced... I mean maybe. Sorry this is interesting to me, I'd like to know more. This would also require very high samplerates so it can do really weird stepping up and down to reproduce frequency? If it can only go up and down there would be some singular ideal frequency and amplitude (but still subject to samplerate loss) and anything other than that / as it gets farther from it causes more and more loss... also it wouldn't be able produce silence... But I suppose it could produce a very high pitched sound that's above the drivers / human hearing instead. Okay... I want to read more about this now haha, I'm probably overlooking something but I can't imagine how a bitrate of 1 could work.

*bit depth of 1, bitrate of 1 would be 1 bit per channel per second, which wouldn’t sound too good
