}Download YouTube video audio
Use this operation to save the audio of one public YouTube video as an audio file (MP3 by default; M4A, WAV, AAC, FLAC, OPUS, Vorbis, or ALAC) with a permanent retained download URL and normalized track metadata. Videos longer than roughly 25 minutes are rejected by the upstream cost guard.
