Sample WMA Files — Download Windows Media Audio Test Files
Windows Media Audio · .wma · MIME type audio/x-ms-wma
Download a sample WMA file — Windows Media Audio, the format Windows Media Player ripped CDs into for a decade and that still lives in corporate archives, dictation systems and old voicemail exports. No browser plays it, so a web product that accepts it must transcode.
The samples are WMA version 2 at 128 kbps in an ASF container, the most common real-world variant.

Frequently asked questions
How do I convert WMA to MP3?
ffmpeg -i in.wma out.mp3 does it, as do VLC and most desktop converters. WMA is lossy, so quality can only go down — convert once, from the original.
Are these WMA files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample WMA files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).
