If you believe the media, didn't MP3 die in like 2017?

Rumours of its death are grossly exagerated!! ;)

It's funny how its detractors have been insisting on flogging this - according to their own expert [cough!] assessment - apparently dead horse for 15 years or so and will keep on doing for the next 15!

A zombie horse perhaps?  :))
Listen to the music, not the media it's on.

It's a paraphrase of words attributed to Mark Twain.

Right, IMO, the "news" that was interpreted as "MP3 was dead" (AKA the last patent expiring) actually made MP3 more alive than it had been in years.

Yep it now a free codec, With a custom decoder would be fun to see a MP3 encoder. That can add new features to fix it limitions & allow 8 ~ 640kbps in VBR, I'm sure their tricks to make older MP3 decoders not freak out if such a thing was made.

I think you'd end up with something that does worse quality-per-bit than and is less compatible than, say, Ogg Vorbis or Opus or a reasonably well supported variant of AAC.

EDIT: if you tried to make something that was "better than" and also "close to but not actually" mp3 technique-wise.

Modern players can use 3rd party decoders for the 8 ~ 640kbps bit i said, But safe mode just locks it too 32 ~ 320kbps for older players. Using modern codec features would be a big gain if it means it can be tranparent at 160kbps instead of 192 ~ 320kbps on current encoders while still being compatible with 99% of mp3 players.

Many people still stick with 192kbps Lame MP3 in 2020, Despite AAC/Opus being around.

Out of spec MP3 is not supported in a VBR configuration, because free format MP3 specifies a packet length of 0xFFFF, which means length is not knowable. You literally have to scan the stream forward for sync headers and process each packet one by one to determine their size.

I saw this article and thought of you .... apparently 14th July 2020 was the 25th Anniversary since the MP3 vile extension was chosen.
