Tips on yt-dlp and YouTube audio quality?

Hi friends,

I've been using yt-dlp to download a few things off of YouTube Music, and I just wanted to ask a few questions about best practice. Right now, I've just been doing it this way:

 bash

    
yt-dlp -f bestaudio -x


  

I've found that has usually downloaded .opus files (though, .m4a as of late—anyone know why this is?), but, I was wondering (for the sake of compatibility with different music players), do I lose anything by passing --recode mp3?

Also, about losing the .opus files, I got this output when I ran yt-dlp -F on a link: ```shell |ID | EXT RESOLUTION FPS CH | FILESIZE TBR PROTO | VCODEC VBR ACODEC ABR ASR MORE INFO

233 mp4 audio only | m3u8 | audio only unknown Default 234 mp4 audio only | m3u8 | audio only unknown Default 249 webm audio only 2 | 1.30MiB 64k https | audio only opus 64k 48k low, THROTTLED, webm_dash 250 webm audio only 2 | 1.64MiB 81k https | audio only opus 81k 48k low, THROTTLED, webm_dash 139 m4a audio only 2 | 1019.36KiB 49k https | audio only mp4a.40.5 49k 22k low, m4a_dash 251 webm audio only 2 | 3.03MiB 149k https | audio only opus 149k 48k medium, THROTTLED, webm_dash 140 m4a audio only 2 | 2.64MiB 130k https | audio only mp4a.40.2 130k 44k medium, m4a_dash

    

Any insights as to why I'm getting that throttling, and why it's downloading m4a instead of opus?
Is it even that much of a difference?
Is there some option I can pass to yt-dlp to avoid this?

Any help is much appreciated!
