What is a .OPUS file?
Opus is a modern, highly efficient lossy audio codec used for streaming and voice.
- Did you know
- Opus was standardised in 2012 and now powers voice chat in Discord, WhatsApp and Zoom.
- Opus was created by merging two codecs: Skype’s speech-oriented SILK and Xiph.Org’s music-oriented CELT.
- It scales from about 6 kbit/s narrowband speech up to 510 kbit/s high-quality stereo music in a single codec.
- WebRTC made Opus a mandatory codec, which is why it became the default for voice and video calls across web browsers.
- On the web a .OPUS file is served with the MIME type
audio/opus.
- 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 .OPUS file
- Drag a .OPUS 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.
