In the fast-paced world where digital communication is key, you need a completely open, royalty-free and extremely versatile audio codec with no incompatibilities and licensing issues.

A codec is necessary for sending and receiving compressed audio files through the internet. It translates audio into compressed digital bits that can be sent through the network – allowing voice and VoIP to function optimally while giving users a richer and more natural sound while using the least amount of bandwidth. Designed for interactive speech and music transmission over the internet, the Opus Codec is an open and versatile audio codec that incorporates technology from Skype’s SILK and Xiph Org’s CELT codec.

What makes Opus better than other codecs?

Unlike some other codecs, such as Speex and Vorbis, Opus is free to use and was specially designed to function efficiently by having a low delay of 5-66.5 ms and the capacity to support high audio quality. It tremendously surpasses the flexibility and voice quality of older type codecs and provides the user with the best audio experience possible. It is easy to use and is highly compatible with a variety of desktop IP phones and soft phones.

In a nutshell, Opus will deliver you from terrible audio quality and voice delays and allow you to have access to high bitrate voice, even over less-than-perfect IP networks.

In low-bandwidth environments, the Opus can accomplish way more than other codecs because of its capacity to drive real-time communications across internet connections that might not previously have supported such communications. The rich and natural translation of sound allows the user to experience the feeling of presently being in the same setting as the speaker at the end of the network. It promotes smooth collaboration for users across different corners of the world while upholding its reputation for highly adaptable, high-quality sound translation. Based on its excellent performance and features, the Opus codec can run just as well on unlicenced frequency fixed wireless broadband and LTE networks.

  • Bitrates from 6 kb/s to 510 kb/s
  • Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband)
