a snarky post at Proper Discord (of course) discussing why bigger audio files are not necessarily better, with a riff on how there's no market for high-end TVs that reproduce infrared and ultraviolet light but ...

We might consider the amount of data required to transmit a page of text. As a text file, it might take up a few kilobytes. If we take a high resolution photograph of the page, it might yield a thousand times as much data, but when it is read aloud, it will sound exactly the same. We could use a microscope to photograph every fibre on the surface of the page, but if what we want to do is read the text, there’s a lot of data there we simply don’t need.

People don’t seem to have a problem with this when it comes to pictures. Nobody says “I won’t look at a website unless all the images are TIFF files”, because that’s plainly ridiculous. We’ve all seen badly compressed images on the Internet, and we’ve all seen beautiful ones too. We understand that “what it looks like” is the reliable measure of, well, what it looks like.

Eyes work differently to ears, though. Eyes are much harder to bamboozle with plausible-sounding pseudoscience. This is why there is no market for super-high-end TVs which reproduce infra-red and ultraviolet light. We all just accept that these are parts of the electromagnetic spectrum that we cannot see, and we leave it at that.
