AAC Audio Format AAC Converter
AAC is one of the most common formats for digital music, in a large part because it is the default format for Apple devices and the iTunes program, as well as some Sony and Nintendo devices. AAC is short for Advanced Audio Coding. It was developed in 1997 and is now an open standard recognised by ISO, the International Organization for Standardization.
Like MP3, the AAC file format uses lossy compression. With both formats there is some loss of audio quality to create smaller file sizes that let users to store and share music more easily. However, with both MP3 and AAC, most listeners cannot hear this loss of quality. AAC also generally produces higher quality sound than MP3. As AAC is a widely used open standard format for digital music, you can play AAC audio tracks with almost all media players, including Apple Music, Windows Media Player, VLC, and Adobe Audition.

MP4 Video Format MP4 Converter
MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.
MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
