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.
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.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.
The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.
Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
