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.

What’s wrong with mp3
Big file size for rather bad audio quality.
I've yet to meet someone who can genuinely pass the 320kbps vs. lossless blind-test on anything but very high-end equipment.
People are able to on some songs because mp3 is poorly optimized for certain sounds, especially cymbals. However, opus can achieve better quality than that at 128k with fewer outliers than mp3 at 320k, which saves a lot of space.
False. OPUS achieves transparency at 192kbps compared to 320kbps for LAME MP3.
Oh, yeah, not arguing that Opus is the superior format. It 100% is. Not questioning that.
Indeed, the first place that gets hit by lower bitrates with MP3 is high frequencies. MP3 does have a pretty harsh cutoff at very high frequencies... that the vast majority of equipment can't reproduce and most ears can't hear. It's relatively debated, some claim to be able to "feel" the overtones or something like that. I'm extremely sceptical, if I'm being honest. Last time I did the test - must have been a decade ago - I couldn't distinguish lossless and high bitrate MP3 any more accurately than a coin toss.
