Some of you might have met the strange file extension as ".opus" when you receive .opus files from somewhere. The .opus file is less common than other popular audio formats, such as MP3, WMA, WAV, and M4V so it is possible that your player can't play OPUS files. If you are wondering what exactly .opus file is and how to convert it to other audio formats(such as MP3) for normal playing, this guide will help you figure it out.
The Internet Engineering Task Force (IETF) creates the .opus format and Xiph. Org develops it. OPUS is a lossy audio codec format, using both SILK and CELT codecs. Technically speaking, it can support a variable bit rate from 6 kb/s to 510 kb/s.
Usually, the OPUS format is used by VoIP applications through the telephone features or voice recording functions, music streaming applications, instant messaging applications. It is simply used to code audio data into a single format. For example, when you are having an audio call or a real-time video conference through the Internet, the audio data during the process will be coded and exported as an .opus file.
Due to this feature, .opus files that you received are probably created by those applications that provide audio-related functions or audio/video streaming services, for instance, the instant messaging apps with which you can make a call.
Though the .opus file is unfamiliar to most people, certain media players can open it.
For Windows PC, you can open .opus file with players such as VideoLAN VLC media player, K-Lite Codec Pack, Zoom Player, Final Media Player.
For Mac, you can use the Mac version of VideoLAN VLC media player to open .opus file.
If you don't want to bother installing these media players on the computer, or if you want to play .opus files on the mobile phone or other devices, it is recommended to convert the .opus files to MP3 format with a .opus file converter.
