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, and play Apple Core Audio (CAF) files such as iMessage voice messages, decoded on-device with FFmpeg where the browser cannot.
- 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.
