AFAIK spotify premium uses 320kb/s vorbis for audio compression. I understand why you'd want lossless for archival purposes, but does it make a difference for playback? ie. can you tell the difference between 320kb/s vorbis and lossless in a ABX test?

The difference will not be audible to most people because of the equipment and environment. Besides, audio has been mastered for 128kbps MP3, which most people prefer. So unless they are going to change the mastering, this is double worthless. But I’m not in the habit of telling people how to spend their money. If they enjoy the music more because they paid more for it, no objections here. I’ve got plenty of wasteful…

Does it make a difference? It certainly sounds different (on my very midrange Audioengine speakers).

I certainly can't consistently identify which one is lossless in a blind test, but there is an audible difference between the same song in Vorbis and FLAC.

I don't know how useful this distinction is though.

Purely marketing for the “more is better” pseudo audiophile. ABX testing blew the “lossless sounds better” mantra out of the window nearly 2 decade ago [1] [1] https://en.wikipedia.org/wiki/Codec_listening_test

There is a cut and dry relationship between bitrate and audio fidelity. You simply cannot encode higher frequency audio in lower bitrate samples. https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampli...

Yes, but for most codecs, bitrate is variable. For the parts where the higher frequencies are present the codec is free to bump up the bitrate and it can also scale it down for silent parts or parts with low frequencies only.

Nyquist is about sample rate and frequency, not bitrate and frequency.

Edit: Clearly there is generally a relationship between bitrate and quality, but for compressed audio it is far from "cut and dry".

That's irrelevant because human ears aren't spectrum analyzers. Audio compression codecs exploit weakness in human perception[1] to discard data with minimal loss of subjective audio quality.

Too bad we have that pesky brain in the way. Human perception isn't just a matter of signal processing theory.
