Meaning
AAC is an audio coding format used in compressed audio and video delivery.
A practical example
An MP4 can contain an AAC narration track while its picture is encoded with a video codec such as H.264.
What to check
Do not compare an audio codec's name directly with an uncompressed sample rate or file extension. Check bitrate, channel layout and playback support too.
