Quick Verdict
Use WAV when…
Use WAV as the default uncompressed audio format — it's the most universally compatible audio format across all DAWs, sample libraries, broadcast systems, and operating systems.
Use AIFF when…
Use AIFF when working primarily in Logic Pro, GarageBand, or Final Cut Pro on macOS — Apple tools have native AIFF support, and AIFF's MARK chunk preserves loop points better for sample libraries and audio loops.

Frequently asked questions
Are WAV and AIFF really the same quality?
Yes — both store raw PCM audio data with no compression or quality loss. A WAV and AIFF file created from the same source at the same sample rate and bit depth produce bit-for-bit identical audio on playback. Any audible difference between WAV and AIFF players is due to the player's DAC, not the file format.
Which should I use for music production?
Use WAV if you work cross-platform or collaborate with Windows users — WAV has fewer compatibility surprises. Use AIFF if you work exclusively in Logic Pro on macOS and need loop points for sample libraries. Both are valid production formats; the practical difference in a modern DAW workflow is negligible. Many producers use WAV as their master format and AIFF only when Logic projects demand it.
Can Logic Pro open WAV files?
Yes — Logic Pro fully supports WAV, including multi-channel WAV files. Logic's default export format is AIFF, but WAV is equally supported for import, editing, and export. In Logic: File → Project Settings → Assets to set the preferred recording format between WAV and AIFF.
