Opus is a totally open and royalty-free audio codec designed for versatile audio applications over the internet, including speech and music transmission.

Opus is a highly versatile audio codec suitable for a wide range of audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It's designed for interactive speech and music transmission over the Internet but also intended for storage and streaming. Opus can scale from low bitrate narrowband speech to very high quality stereo music. It supports bitrates from 6 kb/s to 510 kb/s and sampling rates from 8 kHz to 48 kHz. Frame sizes range from 2.5 ms to 60 ms, with support for both constant and variable bitrates. Opus is standardized by the IETF as RFC 6716, incorporating technology from Skype’s SILK codec and Xiph.Org’s CELT codec, offering good loss robustness and packet loss concealment.

Extends the audio bandwidth by synthesizing higher frequency components from the lower frequency content, improving audio quality without significantly increasing the bitrate. This module was introduced in Opus 1.6 and builds upon ML-based features.
Enables encoding and decoding of high-resolution audio at a 96 kHz sampling rate, capturing a wider range of frequencies for improved fidelity. Implemented with improvements in Opus 1.6
Introduces a mechanism to encode redundant information within the audio stream, allowing for better error correction and resilience to packet loss in noisy network environments. Significantly improved in Opus 1.6.
Offers the flexibility to encode audio using either a constant bitrate, ensuring a consistent data rate, or a variable bitrate, dynamically adjusting the bitrate based on audio complexity. It allows you to prioritize the needs of the transmission.
Reconstructs missing audio frames due to packet loss by predicting the content based on surrounding frames, minimizing the impact of network impairments on audio quality. It is a key feature for real-time applications.
Download the Opus source code from the downloads page.
Extract the downloaded archive (e.g., opus-1.6.1.tar.gz).
Navigate to the extracted directory in your terminal.
Configure the build environment using the `./configure` command.
Compile the Opus library using the `make` command.
Install the library using the `make install` command (requires appropriate permissions).
Link the Opus library in your project and include the necessary header files (e.g., opus.h).
