From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

320 kbps is approaching lossless audio compression bitrates.
Opus does better in about half the space. And goes down to comically low bitrates. And his obscenely small latency. It's not simple, but hot dang, is it good.
The Quite Okay Imaging guy did a Quite Okay Audio follow-up, aiming for aggressive simplicity and sufficient performance, but it's fixed at a bitrate of 278 kbps for stereo. It's really competing with ADPCM for sound effects in video games.
Personally, I think an aggressively simple frequency-domain format could displace MP3 as a no-brainer music library format, circa 128 kbps. All you have to do is get forty samples out of sixty-four bits. Bad answers are easy and plentiful. The trick is, when each frame barely lasts a millisecond, bad answers might work anyway.
