## Public Attributes

int | nSampleRate
| The sample rate to use. Sample rate must be 8000, 12000, 16000, 24000 or 48000 Hz.
int | nChannels
| Mono = 1 or stereo = 2.
int | nApplication
| Application of encoded audio, VoIP or music.
int | nComplexity
| Complexity of encoding (affects CPU usage). Value from 0-10.
bool | bFEC
| Forward error correction. Corrects errors if there's packetloss.
bool | bDTX
| Discontinuous transmission. Enables "null" packets during silence.
int | nBitRate
| Bitrate for encoded audio. Should be between BearWare.OpusConstants.OPUS_MIN_BITRATE and BearWare.OpusConstants.OPUS_MAX_BITRATE.
bool | bVBR
| Enable variable bitrate.
bool | bVBRConstraint
| Enable constrained VBR. `bVBR` must be enabled to enable this.
int | nTxIntervalMSec
| Duration of audio before each transmission. Minimum is 2 msec. Recommended is 40 msec. Maximum is 500 msec.
int | nFrameSizeMSec
| OPUS supports 2.5, 5, 10, 20, 40, 60, 80, 100 and 120 msec. If `nFrameSizeMSec` is 0 then `nFrameSizeMSec` will be same as `nTxIntervalMSec`.

## Member Data Documentation

Definition at line 1046 of file TeamTalk.cs.

## ◆ nChannels

## ◆ nComplexity

int BearWare.OpusCodec.nComplexity

Complexity of encoding (affects CPU usage). Value from 0-10.

Definition at line 1055 of file TeamTalk.cs.

## ◆ bFEC

bool BearWare.OpusCodec.bFEC

Forward error correction. Corrects errors if there's packetloss.

Definition at line 1058 of file TeamTalk.cs.

## ◆ bDTX

bool BearWare.OpusCodec.bDTX

Discontinuous transmission. Enables "null" packets during silence.

Definition at line 1061 of file TeamTalk.cs.

## ◆ nBitRate

int BearWare.OpusCodec.nBitRate

Bitrate for encoded audio. Should be between BearWare.OpusConstants.OPUS_MIN_BITRATE and BearWare.OpusConstants.OPUS_MAX_BITRATE.

Definition at line 1065 of file TeamTalk.cs.

## ◆ bVBR

bool BearWare.OpusCodec.bVBR

Enable variable bitrate.

Definition at line 1067 of file TeamTalk.cs.

## ◆ bVBRConstraint

bool BearWare.OpusCodec.bVBRConstraint

Enable constrained VBR. `bVBR` must be enabled to enable this.

Definition at line 1070 of file TeamTalk.cs.

## ◆ nTxIntervalMSec

int BearWare.OpusCodec.nTxIntervalMSec

Duration of audio before each transmission. Minimum is 2 msec. Recommended is 40 msec. Maximum is 500 msec.

The BearWare.SoundSystem must be able to process audio packets at this interval. In most cases this makes less than 40 msec transmission interval unfeasible.

Definition at line 1077 of file TeamTalk.cs.

## ◆ nFrameSizeMSec

int BearWare.OpusCodec.nFrameSizeMSec

OPUS supports 2.5, 5, 10, 20, 40, 60, 80, 100 and 120 msec. If `nFrameSizeMSec` is 0 then `nFrameSizeMSec` will be same as `nTxIntervalMSec`.
