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.

Hi Lemmy!

This post is a way for me to announce one of my apps that I made for my personal usage.

Azul box

It is a front end for yt-dlp and ffmpeg. It isn't just a yt-dlp downloader; it's more like a utility app that does anything that I need. The "special" part about this software is probably the ability to download YouTube subtitles and then embed them into the audio file as synced lyrics. Well, that is the only "unique" thing about it. As I’m still quite new to programming, there may be some bugs, and I appreciate your understanding. I’m also learning how to package it as a deb/rpm and plan to dedicate time to this during the summer. For now, the only way to download it will be to build from source with the bash install script in my repo.

If you have some time to try the app, I would love to hear your thoughts. Thank you for taking the time to read this! :)

I stoped using yt-dlp frontends the moment I saw youtube actually serving upscaled opus media files (very visible line on a spectrogram). Also their metadata is totally fucked-up and not very well organized and full of shit (comments with huge spaces and non useful metadata...).

Wow really? Are you sure it applies to all audio files? YouTube gathers music records from different companies so they could be of varying quality. To me the opus quality from YouTube was always decent and personally I cannot hear any compression in the audio. The metada is not perfect, but I usually use some tag editor to complete what's missing. YTDLnis on Android does a great job of scraping as much usable metada from YouTube Music as possible.

Not sure if every audio file is upscaled, however I had a few files who clearly were 128kbs mp3 upscaled to ~192kbs opus !

personally I cannot hear any compression in the audio.

100% agree on that xD !! However, I'm some kind of strange audio freak hoarder. If the spectogram of an audio doesn't reflect my standards (not upsacles audio files...) I won't keep/archive it !

Do note that I didn't used a paid YouTube account... Maybe they don't serve HQ audio files to free users? Dunno, but after some digging into the spectograms I was not happy seeing how bad they looked !
