Class ConcentusEncodeFilter
A filter that encodes audio using Opus. Use this as an output filter to reduce the size of outgoing client audio

Syntax
public class ConcentusEncodeFilter : IAudioFilterConstructors
ConcentusEncodeFilter(ConcentusFrequencies, Int32, Int32, Int32, Int32)
Creates a Concentus encode filter
Declaration
public ConcentusEncodeFilter(ConcentusFrequencies encodeFrequency = ConcentusFrequencies.Frequency_16000, int resamplerQuality = 2, int encoderComplexity = 3, int encoderBitrate = 64000, int encodeBufferLength = 46080)Parameters
| Type | Name | Description |
|---|---|---|
| ConcentusFrequencies | encodeFrequency | The frequency the encoder runs at. If the input audio frequency is different from this value, it will be resampled before encode. |
| System.Int32 | resamplerQuality | Resampler quality [1, 10] |
| System.Int32 | encoderComplexity | Encoder complexity [1, 10] |
| System.Int32 | encoderBitrate | Encoder bitrate [16000, 256000]. Set to -1 to enable variable bitrate. |
| System.Int32 | encodeBufferLength | The length of the encode buffer. Default is 46080 to fit a large sample with frequency 48000, duration 120ms and 2 channels. This should be enough for almost all scenarios. Increase if you need more. |
