All audio here is a short instrumental we synthesize ourselves — a pentatonic arpeggio over a soft bass — rendered at 44.1 kHz stereo and then encoded to each format at the stated bitrate. Nothing is sampled from a commercial recording, so there is no licensing question when you ship these files inside a test suite or a demo.
Pick by format, then by duration or bitrate. The metadata column shows codec, sample rate, channels and average bitrate as reported by ffprobe, so the values you see are the values a decoder will see.

Frequently asked questions
Which audio format should I use for browser playback tests?
MP3 plays everywhere. Use AAC/M4A for Apple ecosystems, Opus or OGG for WebRTC and open-source stacks, WAV when you need uncompressed PCM (waveform rendering, DSP unit tests) and FLAC when you need lossless compression. WMA and AIFF are mostly useful for testing that legacy uploads are handled gracefully.
Do the files have ID3 or other metadata tags?
Yes. Every file carries a title, artist (Pine & Birch) and comment tag written by ffmpeg, so tag readers have something to display. If you need untagged variants for edge-case testing, tell us and we will add them.
