Echo Canceller: Acoustic echo canceller (AEC for short) is a kind of digital audio signal processing technology. It is used in audio/video conference when conferees in local conference room are talking with one or more speakers certain distance away. AEC program increases remote speaker’s phonetic intelligibility via cancelling acoustic echo generated in local room. Echo cancellation module for remote calls can be used to carry out local amplification of remote voice signals and attenuate the interference caused by acoustic echo. Its basic operation principle is simulating echo channel, estimating possible echo generated by remote signals and then minus the estimated signal from input signal of microphones, and thus there will be no echo generated in input voice signal to achieve the goal of cancelling echo. There is only an echo cancellation module in DSP Controller. Two local input and remote output mixers are preset to realize multichannel signal participating echo cancellation as shown in the figure. A parameter can be adjusted

Noise Suppression Noise suppression module can remove non-human voice effectively. It may distinguish human voice from non-human voice and treat the latter as noise. After its processing, only human voice is theoretically left for an audio file consisting both human voice and noise
