WAV, built to spec.

Each file is 16-bit stereo PCM audio at 44.1 kHz carrying a quiet 220.5 Hz tone. The size you ask for is reached with audio samples — the whole file is real audio data, so the result opens in media players, Audacity, ffmpeg and Python's wave module. Most people generate these for testing audio upload limits and transcoding queues.

Questions.

How small can a WAV file be?

About 45 bytes. Below that the format cannot carry its mandatory structure, let alone padding.

Will the file open normally?

Yes — it opens in media players, Audacity, ffmpeg and Python's wave module, because the padding lives in audio samples — the whole file is real audio data.

Can I ask for an unusual size?

Any byte count above the minimum works, including values like 3,145,728 or 27.5 MB. Drag the caliper or type the number.
