AAC (.aac) is a modern lossy audio codec offering improved compression over MP3 at similar bit rates. Used extensively in streaming and mobile platforms, it supports various profiles and containers (ADTS, MP4). Use sample .aac files to validate decoder compatibility, stream buffering, and metadata extraction.
