What changes when you convert AIFF to FLAC
Both formats keep the full signal, so this conversion is bit-for-bit safe. Nothing is discarded; only the container and compression scheme change. Size moves from about 21 MB per minute to roughly 6 MB per minute.
Compatibility is the main win here: FLAC plays natively on 3 more of the platforms we track than AIFF does, so the result works without asking anyone to install a player.
A 32-bit master will be reduced to 24-bit, which is the ceiling FLAC supports.
The two formats are aimed at different jobs. AIFF is typically used for studio editing, the Apple ecosystem, mastering, while FLAC is the usual pick for long-term archiving, audiophile listening, CD ripping. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: ID3 chunk (limited) in the source becomes Vorbis comments in the result. Standard fields map cleanly; niche custom tags often do not.
