ALAC
Convert to ALAC when you need lossless music storage or delivery in an Apple-friendly format, especially for personal libraries, hi-fi playback, or archives that sync across Apple devices.
It is appropriate when quality must be preserved but uncompressed AIFF or WAV would be unnecessarily large.
For broader non-Apple-centric archival exchange, FLAC is often the more neutral choice.
