MP4

MPEG-4 file format

MP4 (MPEG-4 Video File) is a widely used digital multimedia container format designed to store video, audio, subtitles, and images, offering high compression efficiency and compatibility across devices. It is supported by popular media players like VLC, QuickTime, and Windows Media Player, as well as editing tools such as Adobe Premiere Pro and Final Cut Pro. The format uses a hierarchical structure with boxes (or atoms) to organize data, supporting advanced features like streaming, metadata embedding, and DRM (Digital Rights Management) for secure content distribution.

AAC

Advanced Audio Coding

AAC (Advanced Audio Coding) is a digital audio coding standard designed to provide high-quality audio at lower bitrates compared to MP3, making it a popular format for streaming and storage. It is widely supported by platforms like iTunes, YouTube, and Android devices, and can be created or edited using tools like Audacity, FFmpeg, and Adobe Audition. The format uses advanced compression techniques, such as perceptual noise shaping and temporal noise shaping, to optimize audio quality while maintaining efficient file sizes, and it supports multiple channels for surround sound and metadata for enhanced functionality.
