Sample AIFF Files — Download Apple Uncompressed Test Audio
Audio Interchange File Format · .aiff, .aif · MIME type audio/aiff
Download a sample AIFF file — Apple's uncompressed PCM format, the macOS equivalent of WAV and the native export of Logic Pro, GarageBand and iTunes' 'AIFF encoder'. The audio is identical to our WAV samples; only the container and byte order (big-endian) differ, which is exactly what trips up decoders that assume little-endian PCM.
AIFF is common in music production, mastering and sound-design handoffs, and large: like WAV, it is 176.4 KB per second at CD quality.

Frequently asked questions
AIFF vs WAV — is there a quality difference?
None; both are uncompressed PCM. AIFF stores samples big-endian and supports slightly richer metadata; WAV is more widely supported on Windows and the web. Convert between them losslessly with any audio tool.
Are these AIFF files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample AIFF files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).
