MixMasterAIAIFF to WAV Converter
AIFF and WAV are both uncompressed PCM — same audio data, different headers. AIFF is big-endian (the Apple convention from the late 80s), WAV is little-endian (the Microsoft convention). The conversion just rewrites the header and flips byte order — there's no quality change, the sample values are preserved exactly.
How it works
Drop the AIFF
.aiff or the older 3-letter .aif extension. ffmpeg handles both.

Pick bit depth (optional)
Default keeps the source bit depth. Choose 16-bit for distribution masters, 24-bit if the WAV will be processed further. Sample rate is preserved unless you override it.
Codec: pcm_s16le or pcm_s24le · standard RIFF

The WAV is bit-identical to the AIFF audio, just with a RIFF wrapper instead of an IFF wrapper.
Standard RIFF WAV, DAW-compatible
Frequently asked questions
Why is AIFF used by macOS and Logic Pro?
AIFF was the standard uncompressed audio format on the original Mac in 1988. Logic Pro inherited it. WAV came from the Windows side a few years later. Today both formats are essentially equivalent — same PCM audio, different container conventions. Logic supports WAV import natively, and any DAW imports both, so the conversion is purely about preference or sending to systems that don't read AIFF.
Will markers and metadata transfer?
Standard tags (artist, title, album) transfer through ffmpeg's metadata copy. DAW-specific markers (loop points, cue lists, region annotations) usually don't survive the conversion — those are stored in proprietary chunks each DAW reads from its own export. If you depend on markers, export from your DAW directly to WAV.
Is the conversion lossless?
Yes. Both formats store uncompressed PCM. ffmpeg copies the sample values into a new container — no resampling, no encoding, no quality change. The output WAV decodes to identical audio.
