What is AAC?
AAC stands for Advanced Audio Coding and it’s a lossy audio file format (meaning it loses some quality when compressed). AAC was designed to be a better version of MP3, by achieving higher sound quality at the same bitrate. AAC is often used as the default file format for the iTunes Store, Apple Music, iPhone and PlayStation.
AAC is compatible with several mobile devices including Nokia, Blackberry, Android and iPhone. It also plays in major media players such as VLC, Media Player Classic (MPC-HC), Windows Media Player and many others.
What is MP3?
An MP3 is a digital audio file that’s compressed so it’s easy to store and transfer. It’s a lossy format, meaning it drops some of the audio’s sound when it’s compressed. Most of this dropped sound is inaudible when you play it back, however. MP3 files can be about one-tenth the size of lossless audio files, making them easy to share, store and play back on most devices.
