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()
