Public Attributes
INT32	nSampleRate
	The sample rate to use. Sample rate must be 8000, 12000, 16000, 24000 or 48000 Hz.

INT32	nChannels
	Mono = 1 or stereo = 2.

INT32	nApplication
	Application of encoded audio, i.e. VoIP or music.

INT32	nComplexity
	Complexity of encoding (affects CPU usage). Value from 0-10.

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

TTBOOL	bDTX
	Discontinuous transmission. Enables "null" packets during silence.

INT32	nBitRate
	Bitrate for encoded audio. Should be between OPUS_MIN_BITRATE and OPUS_MAX_BITRATE.

TTBOOL	bVBR
	Enable variable bitrate.

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

INT32	nTxIntervalMSec
	Duration of audio before each transmission. Minimum is 2 msec. Recommended is 40 msec. Maximum is 500 msec.

INT32	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`.

◆ nSampleRate

INT32 OpusCodec::nSampleRate

The sample rate to use. Sample rate must be 8000, 12000, 16000, 24000 or 48000 Hz.

Definition at line 1153 of file TeamTalk.h.

◆ nChannels

INT32 OpusCodec::nChannels

Mono = 1 or stereo = 2.

Definition at line 1155 of file TeamTalk.h.

◆ nApplication

INT32 OpusCodec::nApplication

Application of encoded audio, i.e. VoIP or music.

Definition at line 1159 of file TeamTalk.h.

◆ nComplexity

INT32 OpusCodec::nComplexity

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

Definition at line 1162 of file TeamTalk.h.

◆ bFEC

TTBOOL OpusCodec::bFEC

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

Definition at line 1165 of file TeamTalk.h.

◆ bDTX

TTBOOL OpusCodec::bDTX

Discontinuous transmission. Enables "null" packets during silence.

Definition at line 1168 of file TeamTalk.h.

◆ nBitRate

INT32 OpusCodec::nBitRate

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

Definition at line 1171 of file TeamTalk.h.

◆ bVBR

TTBOOL OpusCodec::bVBR

Enable variable bitrate.

Definition at line 1173 of file TeamTalk.h.

◆ bVBRConstraint

TTBOOL OpusCodec::bVBRConstraint

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

Definition at line 1176 of file TeamTalk.h.

◆ nTxIntervalMSec

INT32 OpusCodec::nTxIntervalMSec

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

The 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 1183 of file TeamTalk.h.

◆ nFrameSizeMSec

INT32 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.
