AAC (Advanced Audio Coding) is a lossy digital audio compression standard designed to succeed MP3, offering better sound quality and smaller file sizes. Widely used in streaming and supported by many devices, AAC files typically have the ".aac" extension.

MP4 (MPEG-4 Part 14) is a container format that stores audio, video, and other data like subtitles, known for its compression efficiency. MP4 files use the ".mp4" extension and are common in multimedia applications. While AAC focuses on audio quality, MP4 combines audio and video for broader purposes.
