Sample MP3 Files
MP3 is the most common lossy audio format. Samples cover constant bitrates from 32 to 320 kbps, VBR and mono, durations from a few seconds to 3 hours, sizes from 100 KB to 100 MB, a file with ID3 tags and cover art, and classic test signals: a 440 Hz tone, a 20 Hz–20 kHz sweep, a left/right channel test and silence.

FAQ
What music is in these files?
An arpeggio over a C–Am–F–G chord progression synthesized by our generator script. There is no copyrighted material.
Which file should I use to test an audio player?
Start with the 30-second 128 kbps file. Use the left/right test to check channel order, the sweep to check frequency response, and the 60-minute or 3-hour files to test seeking and long-duration playback.
Do any files have ID3 tags or album art?
Yes. The “ID3 tags and cover art” sample has ID3v2.3 title, artist, album, year, track, genre and comment frames plus an embedded 600×600 JPEG cover.
What is the difference between the CBR and VBR files?
CBR files use the same bitrate for every frame, so size is predictable. The VBR (V0) file varies the bitrate with the content, which is a good test for duration estimates and seek accuracy.
Can I load these files directly from my code?
Yes. Files are served from files.samplefiles.com with permissive CORS headers, so fetch(), <video>, <audio> and <img> can use the URLs directly.
