Audio

Sample audio files in MP3, WAV, OGG, FLAC, AAC, M4A, and WMA, ranging from a few kilobytes up to about 15MB.

What these files actually are

Every file below is a real, valid audio file - generated with ffmpeg from a real sine-wave tone, encoded into the format itself - so it actually plays in an audio player, not just a size-and-extension placeholder.

Are these files safe to download?

Every sample file is generated by us — no executable code, no macros. Files are served over HTTPS from our CDN, each with a SHA-256 checksum so you can verify your download and a link to an independent VirusTotal scan report.

Common use cases

Voice-note and podcast upload testing

Check that a recording or podcast-upload feature accepts the formats you expect and handles a range of realistic file sizes.

Email attachment limit checks

Confirm your mail client or server correctly enforces its attachment size limit before or after sending.

Storage quota testing

Fill a test library or bucket with audio files of varying sizes to see how the system behaves near a quota.

Player format-rejection checks

Confirm an audio player or widget rejects an unsupported format by extension rather than failing silently mid-playback.

Frequently asked questions

Will these files actually play?
Yes. Each one is a real, valid audio file - a genuine tone, encoded for real - so it plays in any standard audio player.
What are they useful for, then?
Checking an upload size limit on a website or app, accepted audio extensions, email attachment limits, or storage and bandwidth handling.
What's a realistic size to test with?
A short voice note is usually under 1MB, while a podcast episode can run into the tens of megabytes — pick a size close to what your real users will upload.
Can I use these in an automated test suite?
Yes. Each file has a stable, direct URL, so you can fetch it in a CI pipeline instead of committing large binary fixtures to your repository.
Which formats are available?
MP3, WAV, OGG, FLAC, AAC, M4A, and WMA.
