This is a 529 KB sample WAV file — exactly 529,380 bytes, generated by us rather than scraped, so the size is deliberate and the contents are free of anyone else's copyright. 3s • 16-bit 44.1 kHz (3 s · PCM_S16LE · 1411 kbps · 44.1 kHz · stereo). Use it to test an upload limit near 529 KB, to time a transfer, or as a fixture whose hash never changes.
Sizes here are decimal: 529 KB means 529,380 bytes, not 0.50 MiB. If your limit is expressed in binary units, check the exact byte count above before assuming this file is under it.

Frequently asked questions
How big is this WAV file exactly?
Exactly 529,380 bytes (529 KB using decimal units, where 1 MB = 1,000,000 bytes). Binary-unit tools will show a slightly different number: 0.50 MiB. The SHA-256 on this page lets you confirm you received the same file byte for byte.
What can I test with a 529 KB WAV file?
Upload size limits that sit near 529 KB, transfer timing, storage quotas, and any pipeline that behaves differently above or below a size threshold. Pick the file just under and just over your limit to find out whether the limit is inclusive.
Is this file free to use commercially?
Yes. It is generated from scratch by our own open script — no third-party copyright, no scripts or macros inside — and free for any purpose including commercial products and redistribution, with no attribution required.
