# Sample AIFF audio files for testing, free, CC0 and hotlinkable 1 AIFF test file of 529.3 KB. A direct URL, the file's SHA-256 and CC0, so curl and CI can fetch it with no signup and no keys. The page: . AIFF is Apple's uncompressed audio container and the byte-order twin of WAV: the same kind of PCM samples, stored big-endian instead of little-endian. A reader that assumes little-endian samples does not crash on an AIFF file; it plays loud noise. That silent failure is what `aiff/3s.aiff` exists to catch. The file holds three seconds of a 440 Hz sine wave as 44.1 kHz, 16-bit stereo PCM. Because the signal is a pure tone, a byte-order mistake is unmistakable in a waveform view, and a correct decoder produces a clean, steady pitch. Use it to test audio libraries, format sniffers that must tell AIFF from WAV by its `FORM` header, and converters that move audio between Apple and Windows tooling. Compare it with the little-endian [WAV](https://loremfile.dev/wav) files, or with [FLAC](https://loremfile.dev/flac) for the same kind of audio compressed without loss. ## Files | Path | Size | MIME | Properties | |---|---|---|---| | [`aiff/3s.aiff`](https://loremfile.dev/aiff/3s.aiff) | 529.3 KB (529,254 bytes) | `audio/aiff` | 3 s, pcm_s16be, 44.1 kHz, 2 channels | The same list as JSON: .
