Convert to AAC

AAC is the successor to MP3, delivering better quality at equal bitrate — the standard audio codec for video platforms and mobile streaming. This group transcodes MP3 and video soundtracks to AAC — 2 conversion directions.

The quality parameter maps to 64-256kbps. Raw AAC streams carry no metadata container, suiting video workflows and streaming delivery; choose M4A when tag information is needed.
