I worked in this space on the CDN non-pirate side and it's basically the same thing but everyone (including the major ones you know) distribute all of their content like that over various cdns and they're all essentially pitted cost/error-rate/latency wise against one another to the bottom. If you're interested in some of the tools used that essentially re-compiles, allows you to interject interstitial ads based... - Source: Hacker News / 3 months ago

An audio stream encoded as Vorbis, at 48000 samples per second, in stereo audio. - Source: dev.to / about 2 years ago

I'm not sure if I'm missing something, but I've seen ogg/vorbis bitrates in excess of 128 kbps mentioned in several places (supposedly Spotify can stream vorbis at a maximum of 320 kbps), while the xiph.org foundation states that the maximum bitrate per channel is 128 kbps. Assuming that for typical stereo audio this comes to 256 kbps, what is the meaningful comparison with something like e.g. Mp3 at 320 kbps?... Source: almost 3 years ago

But what about audio file formats like mp3, ogg, and flac? The difference between these formats and wav is that the audio is compressed on disk. Mp3 and ogg are what's called "lossy" compression - that means they change the actual sound in ways that are hopefully imperceptible to most listeners in order to get better compression. flac, meanwhile, is a format that implements lossless compression. This means that it... - Source: dev.to / about 3 years ago
