Public Attributes | ||
struct { | ||
TTBOOL bEnable | ||
Enable pre-amplifier. Replacement for TT_SetSoundInputGainLevel() More... | ||
float fFixedGainFactor | ||
Gain factor. Default: 1. More... | ||
} | preamplifier | |
Configuration of WebRTC pre-amplifier. | ||
struct { | ||
TTBOOL bEnable | ||
Enable WebRTC echo canceller. The WebRTC echo canceller requires sound input and output devices are initialized using TT_InitSoundDuplexDevices(). This is because both input and output device must use the same sample rate. More... | ||
} | echocanceller | |
Configuration of WebRTC's echo canceller. See also TT_SetSoundDeviceEffects() | ||
struct { | ||
TTBOOL bEnable | ||
Enable WebRTC noise suppression. More... | ||
INT32 nLevel | ||
Noise suppression level. 0 = Low, 1 = Moderate, 2 = High, 3 = VeryHigh. Default: 1. More... | ||
} | noisesuppression | |
Configuration of WebRTC's noise suppression. See also SpeexDSP. | ||
struct { | ||
TTBOOL bEnable | ||
Use WebRTC's voice detection to trigger CLIENTEVENT_VOICE_ACTIVATION. More... | ||
} | voicedetection | |
Configuration of WebRTC's voice detection. | ||
struct { | ||
TTBOOL bEnable | ||
Enable WebRTC's fixed digital gain. WebRTC's automatic gain control (AGC) More... | ||
struct { | ||
float fGainDB | ||
Gain level in dB. Range: 0 <= x < 50. Default: 0. More... | ||
} fixeddigital | ||
Gain level for AGC. Only active when bEnable is true. More... | ||
struct { | ||
TTBOOL bEnable | ||
float fInitialSaturationMarginDB | ||
float fExtraSaturationMarginDB | ||
float fMaxGainChangeDBPerSecond | ||
float fMaxOutputNoiseLevelDBFS | ||
} adaptivedigital | ||
Configuration for fine tuning gain level. More... | ||
} | gaincontroller2 | |
Configuration of WebRTC's gain controller 2 for AGC. | ||
struct { | ||
TTBOOL bEnable | ||
Enable level estimater. When enabled TT_GetSoundInputLevel() will return a value based on WebRTC's level estimater. A WebRTC level estimater value of 0 will result in SOUND_VU_MAX and level estimater value of 127 will return SOUND_VU_MIN. More... | ||
} | levelestimation | |
Configuration of WebRTC's level estimater. | ||
WebRTC's audio preprocessor.
Use WebRTC's audio preprocessor, https://webrtc.org
Note that WebRTC's can only operate on 10 msec audio frame, so nTxIntervalMSec
in AudioCodec must a multiple of 10.
WebRTCAudioPreprocessor is recommended to TT_SetSoundDeviceEffects() on desktop platforms.
Activate WebRTCAudioPreprocessor by calling TT_SetSoundInputPreprocessEx().

TTBOOL WebRTCAudioPreprocessor::bEnable |
Enable pre-amplifier. Replacement for TT_SetSoundInputGainLevel()
Enable level estimater. When enabled TT_GetSoundInputLevel() will return a value based on WebRTC's level estimater. A WebRTC level estimater value of 0 will result in SOUND_VU_MAX and level estimater value of 127 will return SOUND_VU_MIN.
Enable WebRTC's fixed digital gain. WebRTC's automatic gain control (AGC)
Use WebRTC's voice detection to trigger CLIENTEVENT_VOICE_ACTIVATION.
Enable WebRTC noise suppression.
Enable WebRTC echo canceller. The WebRTC echo canceller requires sound input and output devices are initialized using TT_InitSoundDuplexDevices(). This is because both input and output device must use the same sample rate.
TT_EnableVoiceActivation() must still be called to activate voice detection event CLIENTEVENT_VOICE_ACTIVATION.
Enabling WebRTC's voice detection invalidates use of TT_SetVoiceActivationLevel()
