Would you like a five minute lecture on frequency response and bandwidth of what you upload based on the dynamics compression, filtering, and other processing YouTube does to make videos sound good and all of which have nothing to do with a transport compression algorithm, but how said transport algorithms reduce bandwidth when double compressed because you’re probably not uploading 32-bit PCM to YouTube, and how none of that matters anyway because most people uploading to YouTube aren’t familiar with a spectrogram nor DC offset? (Seriously, one track I got via youtube-dl was the most offset I’d seen in my life. They either don’t fix it, or the fix goes horribly awry.) I’d simply offer it but this thread thinks I’m an angry ranter so I’m making you not cower in fear out of respect.
