What is a .MP3 file?
MP3 is the most common lossy audio format, compressing music to small files with near-universal device support.
- Did you know
- MP3 was finalised by Germany’s Fraunhofer Institute in 1993 and went on to ignite the digital-music revolution.
- Engineer Karlheinz Brandenburg famously tuned MP3 encoding using Suzanne Vega’s a cappella “Tom’s Diner”, earning her the nickname “the mother of the MP3”.
- MP3 is properly MPEG-1 Audio Layer III, the most advanced of the three audio layers defined in the MPEG-1 standard.
- The very first files to be distributed as MP3s appeared in July 1995, the year the “.mp3” extension was chosen.
- On the web a .MP3 file is served with the MIME type
audio/mpeg.
- What Analyser shows you
- Inspect the waveform, spectrogram, codec, bitrate, channels, and tags of MP3, WAV, FLAC, M4A, AAC, OGG, and Opus audio.
- Open a .MP3 file
- Drag a .MP3 file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
