Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.

It is definitely the most well-supported format, however, it provides lower sound quality than the lossless FLAC and ALAC above. Of course, if you wish to play FLAC on Mac, there’s certainly a way - apps such as the Elmedia Player can do just that. The only difference comes in terms of device compatibility: ALAC is an Apple-specific format which can be played by iTunes. These two formats are pretty much equal in terms of sound quality. FLAC, ALAC, AAC, M4A, WMA: What’s the Difference?įLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) are lossless formats, designed for high fidelity sound.
