AAC
Advanced Audio Coding
AAC is the successor codec to MP3 and the audio track in most MP4 video. A bare .aac file is raw ADTS-framed audio with no container, which some players handle poorly.

Opening a .aac file
If you landed here because something handed you a .aac file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
