Sample MP3 File Download

MP3 (MPEG Audio Layer III) uses lossy compression to strip out frequencies the human ear barely perceives, shrinking audio files to a fraction of their uncompressed size. That tradeoff — smaller files at a small, mostly inaudible quality cost — is exactly what made it the format that took over digital music distribution in the first place.

Because the compression is lossy, quality depends heavily on bitrate: a 128kbps MP3 and a 320kbps MP3 of the same source sound noticeably different, which is worth knowing if you're testing audio processing code that needs to handle a range of encoding quality.

Download the sample below to test audio playback, metadata parsing (ID3 tags), or upload handling against a real MP3 file.
