About ALAC and AAC
ALAC: ALAC is Apple's lossless format. It compresses audio to roughly half the size of WAV with zero quality loss and plays natively in Apple Music, iTunes and on every iPhone. It is saved with the .m4a extension.
AAC: AAC is the successor to MP3 and the audio codec behind YouTube, iTunes and most streaming services. A .aac file stores the raw AAC stream without an MP4 wrapper.
