What is AAC?
AAC is the lossy audio codec designed as the successor to MP3 and delivers better quality at the same bitrate. Raw .aac files hold the audio stream on its own, while the same audio usually lives inside an M4A or MP4 container.
Common uses for AAC
- Smaller music files than MP3 at the same quality
- Audio for streaming and mobile apps
- Extracting an AAC stream for players that expect .aac
Note: Raw AAC files carry little metadata such as cover art or tags; M4A is better for music libraries.
Compatibility: Supported by iOS, Android, Windows, macOS, browsers and nearly all current players.
