Opus is a totally open protocol and highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications.
LQ uses the Opus codec to allow high quality, low bandwidth audio connections across LAN, WAN or Public Internet connections
Opus can handle a wide range of audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It can scale from low bitrate narrowband speech to very high quality stereo music. Supported features are:
    Bitrates from 6 kb/s to 510 kb/s
    Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband)
    Frame sizes from 2.5 ms to 60 ms
    Support for both constant bitrate (CBR) and variable bitrate (VBR)
    Audio bandwidth from narrowband to fullband
    Support for speech and music
    Support for mono and stereo
    Support for up to 255 channels (multistream frames)
    Dynamically adjustable bitrate, audio bandwidth, and frame size
    Good loss robustness and packet loss concealment (PLC)
    Floating point and fixed-point implementation
