AIFF — 1 kHz Sine Tone
A pure 1 kHz sine tone stored as AIFF — Apple's big-endian 16-bit PCM container, 3 seconds, 44.1 kHz mono. A clean reference for testing AIFF decoders and WAV↔AIFF conversion.

What is a .aiff file?
AIFF (Audio Interchange File Format) is an Apple-originated container storing uncompressed big-endian linear PCM audio. It is functionally analogous to WAV but uses a different chunk layout and byte order, offering lossless high-fidelity sound. It is common in professional audio on macOS.
How to use this file
Use an example AIFF to test big-endian PCM parsing, cross-platform audio import, and converters that translate between AIFF and WAV or compressed formats.
How to use this file for testing
“AIFF — 1 kHz Sine Tone” is a deterministic Novus Examples fixture for Audio analysis, Conversion testing. Pure tones, sweeps, and noise with known frequencies and levels for testing spectrum, level, and waveform tools.
Documented properties for this file: 16-bit · 1 ch. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Media fixtures are short and synthetic by design. Prefer waveform or transcript ground truth in the same group when measuring ASR, trim, upscale, or sync tools; do not assume broadcast-quality masters.
