Why convert AIFF to WAV?

AIFF and WAV are technically equivalent — both are uncompressed lossless audio formats storing raw PCM data. The practical difference is platform origin: AIFF was invented by Apple in 1988 and is natively supported on macOS and iOS. WAV was invented by Microsoft and IBM in 1991 and is the universal standard on Windows and in professional audio globally.

The conversion is necessary in cross-platform workflows. A Pro Tools session on Windows may not recognise AIFF files from a Logic Pro session on Mac without a specific codec. Broadcast facilities, podcast distribution platforms, and game engine asset pipelines often mandate WAV. Video editors (Adobe Premiere Pro on Windows, DaVinci Resolve) handle WAV more reliably than AIFF in cross-platform projects. Splice, Looperman, and sample marketplace platforms typically require WAV for sound pack submissions.

Because both AIFF and WAV store identical audio data (uncompressed PCM), converting between them is mathematically lossless — not a single sample changes. The output WAV is bit-for-bit identical to the AIFF source in terms of actual audio information. Only the file container changes.

File size is essentially unchanged — a 30 MB AIFF becomes a 30–32 MB WAV. The slight difference comes from the container metadata structure, not the audio data.

Common reasons to convert AIFF to WAV:

  • ›Submit sound files to a Windows-based production house or broadcast facility that requires WAV
  • ›Upload samples to Splice, Looperman, or other sample marketplaces that mandate WAV
  • ›Use Mac-produced audio assets in Windows-based game development projects
  • ›Ensure compatibility when collaborating on music production across Mac and Windows

Quality & file size: AIFF to WAV

Typical sizes (3-minute song): AIFF 30–50 MB → WAV 30–50 MB.

WAV output is 16-bit PCM, so a 24-bit source is reduced to 16-bit (CD quality).

Frequently asked questions

Is AIFF to WAV conversion lossless?
Yes — completely lossless. Both AIFF and WAV store uncompressed PCM audio data. Converting between them changes only the file container header, not the audio samples themselves. The resulting WAV is bit-for-bit identical in audio content to the source AIFF. No quality is lost, and no frequency content is removed.
What is the difference between AIFF and WAV?
AIFF (Apple) and WAV (Microsoft/IBM) both store raw uncompressed PCM audio — the same audio data, two different container formats. AIFF is native to macOS/iOS; WAV is native to Windows. Both are lossless. Both are large files. Both are standard in professional audio production. The choice between them is purely about platform compatibility: AIFF for Apple-centric workflows, WAV for Windows and cross-platform compatibility.
