Being very old I can remember when Capital Radio said that they were
achieving hi-fi because they had ditched vinyl and were only
broadcasting CD originated material on FM - with all these electronic
digital signals these days it is hard to know what is what. I believe
mp3 is not regarded as hi-fi and flac is - but what does that mean when
it comes to Bluetooth - and I assume high bitrate wifi does quality?
After all umra knows everything.
I'll only answer parts:
mp3 - and the earlier mp2 used by DAB - _can_ be hifi, or not; it
depends on the bitrate and the original material; IMO/E, stereo material
with components up to 15 kHz sampled at 44100, which covers the majority
of material extracted from YouTube, is fine at a data rate of 96 kbps as
long as it doesn't contain bursts of white noise or long applause. Other
material - especially old and/or mono - can be encoded at much lower
rates (anyone interested ask me for details) with no _degradation_.
(Whether that counts as hifi, I leave to you.)
mp3 _can_ distort horribly, if too low a data rate is used.
(mp2 - DAB - follows the same answer; it just needs a higher bitrate to
work. From what I've read, it hardly ever gets what it needs on DAB,
except sometimes on Radio 3.)
Bluetooth is a transmission protocol. You can pass good or bad mp3 files
over it (or any other form of data).
