Understanding AVI and AAC file formats

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft. It can contain both audio and video data in a file container that allows synchronous audio-with-video playback. AVI files are popular due to their ability to maintain high-quality video and audio.

AAC (Advanced Audio Codec) is a standardized, lossy compression and encoding scheme for digital audio. It is designed to be the successor of the MP3 format, offering better sound quality at similar bit rates. AAC is widely used in various platforms, including Apple devices and streaming services.
