Tip for those who are looking at the compression ratios thinking "so what?": look at the run-times. It's a minimum of 3x faster than its contemporaries.

According to the author, right? Those results aren't backed up by Porcus's comments in that thread.

It seems the world made a collective yawn about flac. Hard to imagine that would change much with a new format.

I personally keep everything in flac, but Bandcamp is seemingly the only service where that is a given.

For what looks at first glance to be a potentially impactful development, this post and the "encode.su" one linked from it are extremely sparse on details.

Where is the source code? A detailed description of what the codec actually does? References to relevant publications?

All I see are two mystery Windows binaries, hosted on a forum I've never heard about. The fact that "encode.su" uses the world's most notorious domain extension doesn't inspire confidence, to put it mildly.

FLAC level 5 encode times should be WAY longer than decode times. FLAC level 0 to FLAC level 5 is a huge step up and encoding should be way longer (like factor of 3). Under no circumstances should FLAC level 5 decode be faster than FLAC level 0 decode.

These are basic sanity checks.

Something is wrong in the benchmark.
