What is AIFF?

Audio Interchange File Format (.aiff). AIFF is Apple's uncompressed audio format, the Mac counterpart of WAV. It keeps every sample, so it is used in music production on macOS, and files are as large as WAV.

Common use: Music production on macOS, Logic Pro and GarageBand

Output format

What is ALAC?

Apple Lossless Audio Codec (.alac). ALAC is Apple's lossless codec: like FLAC it decodes to exactly the original audio, at roughly half the size of WAV. Apple released it as open source in 2011; iTunes, Apple Music and iPhones play it natively.

Common use: Lossless music on Apple devices
