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.
