Para descargar cualquier audio de cualquier video de YouTube: yt-dlp -f bestaudio

βœ… Correct syntax for fallbacks

yt-dlp -f "233/140/251" URL
  • 233/140/251 means:

    Try format 233, if not available then 140, if not then 251.


πŸ”€ Difference between separators

  • / β†’ fallback (first available one is used).
  • + β†’ combine (e.g., video+audio).
  • , β†’ download multiple formats at once.

Example

If you want Opus (251) but fallback to M4A (140):

yt-dlp -f "251/140" URL

If you want video 137 with audio 251 but fallback to 140 if 251 isn’t available:

yt-dlp -f "137+251/140" URL

⚑ Pro tip: If you just want the best available audio without worrying about IDs:

yt-dlp -f "bestaudio" URL

Do you want me to show you how to prefer Opus > M4A > MP3 automatically so you don’t have to type IDs every time?
