MPEG Audio Layer III
Free MP3 test files at different bitrates, sample rates and channel modes - original music, safe to use anywhere.
MP3 is the classic compressed audio format and still the safest choice for compatibility.
It throws away sounds people hardly hear, so a 3-minute song fits in about 3 MB at 128 kbps.
All files play the same short piece, written for this page, so you can compare quality between bitrates directly.
Trim a file with the MP3 Cutter or join several with Merge MP3.

Yes. The music was composed and generated by ConvertICO for this page. Use it for testing, demos and tutorials without attribution.
CBR keeps the same bitrate for the whole file, so size and duration are easy to calculate. VBR changes bitrate per frame for better quality per megabyte, but some old players show the wrong length.
128 kbps is the most common. 320 kbps is the highest MP3 allows, and 64 kbps mono shows how tools handle low-quality voice-style files.
Every file has a title and artist. The 192 kbps file has full ID3v2.3 tags, handy for testing tag readers and editors.
Click Try it under any file. It opens in the MP3 Cutter with the file already loaded.
