We are using Texas Instruments Audio Codec TLV320AIC3107.
We are using SMD Microphone in SE mode and connected to MIC3L & Speaker connected to SPOM & SPOP.
We are applying echo cancellation on audio codec side(software codec).
In this process we have selected the AEC supported by the SPEEX audio codec as the default one during the active VoIP call.
Whereas the echo suppression is supported by PJSIP.
We have also tried Half duplex communication in our system but it doesn’t show expected results.
Below are the settings we are applying to eliminate echo in our system:
#define PJMEDIA_HAS_SPEEX_AEC 1
#define PJMEDIA_ECHO_SUPPRESS_FACTOR 16 (This value is used for Half duplex communication)
#define PJMEDIA_CODEC_SPEEX_DEFAULT_QUALITY 9
Can you please suggest any changes for echo cancellation.
