What is a .aac file?
audio/aac
AAC (Advanced Audio Coding) is a lossy audio format that generally outperforms MP3 at the same bitrate, standardized as part of MPEG-2 and MPEG-4. Raw AAC streams use ADTS framing, while AAC is also commonly wrapped in M4A or MP4 containers. It is the default audio codec for Apple, YouTube, and streaming.
How to use a .aac file
Use an example AAC file to test decoder support, ADTS frame parsing, and audio pipelines that must handle both raw streams and container-embedded AAC.
