}Notes
- If the video has no audio track, the request returns a 400 error.
- MP3 is lossy but widely compatible. WAV is lossless but large. M4A (AAC) offers a good balance of quality and size.
- When the source audio is already AAC and the output format is M4A, the audio stream is copied without re-encoding.
