What is an AAC (Advanced Audio Coding) file?

Advanced Audio Coding (AAC) is a digital audio file format that reduces file size via lossy compression. Its primary uses are digital TV, digital radio, and Internet streaming. It is the standard audio format for iOS, YouTube, Nintendo, and Playstation. ISO/IEC designated the AAC codec as an improvement to MP3, due its ability to compress file size more efficiently while providing quality similar to uncompressed audio.

How to open an AAC file?

For best results, use VLC media player to open AAC files. Alternatively, AAC also opens by default in iTunes. AAC files are ubiquitous, however, and open in many other programs and software.

Additionally, since AAC files often serve as the audio files for video games, they open on most popular gaming consoles, such as Nintendo 3DS and Playstation 4.

What is an AVI (Audio Video Interleave) file?

Audio Video Interleave (AVI) is a multimedia container developed by Microsoft. AVI is a descendant of the Resource Interchange File Format (RIFF). With the assistance of third-party programs, AVI can support chapters, captions, subtitles, menus, streaming, attachments, and 3D containers.

How to open an AVI file?

Microsoft provides a downloadable and free AVI Viewer. Another way to view an AVI file is to use a version of Microsoft Windows Media Player that is compatible with the operating system.

While AVI files are optimized for the Internet, hardware players support them as well. If an AVI file does not open, then use VLC media player.
