Are you able to download any of these Webm videos? :
https://www.youtube.com/watch?v=RfXcGqzSvaI Webm with Vorbis Ogg 448 kbit/s soundtrack
https://www.youtube.com/watch?v=207ziMjUFzY Webm with Iibopus Opus 512 kbit/s soundtrack
If so, then:
1. Please download them as Webm streams
2. Please download SPEK http://spek.cc/
2. In SPEK, please click: file/open/all files, to open Webm files
3. In SPEK, please save the displayed spectrum as a png picture
4. Please give me a link to the spectrum picture
I am eager to see those spectrum pictures, to see if YouTube allows uploaded Webm files to retain their Ogg or Opus soundtrack untouched? Or if YouTube processes down the soundtrack to something inferior?
Please don't waste your time on downloading any mp4 streams for me. On March 28th 2016 YouTube slashed the sound quality of new HD uploads from Mp4 AAC 192 kbit/s HiFi to 126 kbit/s LoFi. I uploaded the test videos yesterday well after year 2016, so I know in advance that the mp4 streams are pure garbage. (Hint: never upload mp4 files to YouTube yourself...)
But I think I am on the verge of finding a new loophole to HiFi uploads at YouTube? Webm and/or MKV uploads might possibly be allowed to retain their Ogg/Opus soundtrack untouched by YouTube's video processing?
But YouTube started to block most video grabbers in mid-2019, so I cannot even download my own privates videos anymore. And I need to download them, in order to check with SPEK if the loophole exists or not.
Trying to ensure the best possible sound quality at YouTube is like playing chess against a semi-pro. So please help me to checkmate YouTube by downloading those Webm pawns if you can?
