Quick Verdict
Use AIFF when…
Use AIFF when working in an Apple ecosystem — Logic Pro, GarageBand, or professional Mac-based audio production. AIFF's better metadata support is an advantage for organized music libraries.
Use WAV when…
Use WAV for cross-platform professional audio — DAWs on Windows, broadcast delivery (WAV is the broadcast standard), and any context where maximum compatibility is needed.

Frequently asked questions
Is AIFF or WAV higher quality?
Neither — they're acoustically identical. Both store uncompressed PCM audio with no quality loss. Any AIFF can be converted to WAV with zero quality loss, and vice versa. Choosing between them is purely about compatibility and workflow, not audio quality.
What is BWF (Broadcast WAV Format)?
BWF is WAV with additional metadata chunks defined by the European Broadcasting Union. BWF WAV supports timecode, unique file identifiers, and originator information. Pro Tools, most broadcast recorders, and professional field recorders output BWF WAV. BWF WAV is fully backwards compatible with standard WAV.
