    AAC is an audio file format created to offer higher-quality music files at lower bitrates than MP3. AAC has been in widespread use since 1997 and has become the de facto digital audio codec used by YouTube, iTunes, Apple iPhone/iPod/iPad platforms, among other devices and platforms. AAC file formats employ a lossy compression algorithm to decrease data size while still preserving sound quality, by eliminating overtones that fall outside human hearing range and decreasing low frequency components that don't contribute directly to speech or music. Furthermore, AAC uses more sophisticated psychoacoustic models to estimate signal changes, further improving coding efficiency compared to MP3 and other audio codecs. Comparative to MP3, AAC files tend to be two times smaller while providing improved sound quality at the same bitrate. Most media players support AAC audio file formats and can be played both Macs and PCs.
