OpusConductor

OpusConductor is a wrapper around the official libopus, and makes it easy to encode and decode audio. The library is mainly suited for VoIP applications and at the moment only provides libopus binaries for Windows (compiled with the Win10 SDK).

Getting Started

Installation

Install OpusConductor via the NuGet Package Manager:

Install-Package OpusConductor

Basic Usage

A simple example of encoding and decoding audio:

using (var encoder = new OpusEncoder(OpusOptimizer.Clarity, OpusSampleRate._48k, OpusAudioChannels.Stereo)
{
    VBR = true // Variable bitrate
})
using (var decoder = new OpusDecoder(OpusSampleRate._48k, OpusAudioChannels.Stereo))
{
    // 40 ms of silence at 48 KHz (2 channels).
    byte[] inputPCMBytes = new byte[40 * 48000 / 1000 * 2 * 2];
    byte[] opusBytes = encoder.Encode(inputPCMBytes, inputPCMBytes.Length, out int encodedLength);
    byte[] outputPCMBytes = decoder.Decode(opusBytes, encodedLength, out int decodedLength);
}
