What is an ALAC file?
ALAC stands for Apple Lossless Audio Codec. It's an audio codec developed by Apple used for lossless audio compression. It reduces the file size of original audio files without losing the audio quality. ALAC typically uses the MP4 container format to store audio data with the .m4a extension, similar to AAC. ALAC is mainly used in the Apple ecosystem, but it's also supported by many other devices and software, such as VLC media player, foobar2000, and Android devices.
