In any hands-free communication system, where a loudspeaker and a microphone are placed in the same room, the acoustic echo is generated. At the opposite side of the communication system, a talker will hear its voice back due to the fact that the microphone is picking up its voice reproduced by the loudspeaker.
The acoustic echo is an annoying effect and can cause a communication to be impossible. To overcome this problem an acoustic echo cancellation solution is necessary: its target is to completely cancel the echo signal while, at the same time, let the desired speech signal to be transmitted.
bdSound solution for Acoustic Echo Cancellation, bdAEC, is a robust and field-proven full-duplex algorithm implementation that cancel the echo in any hands free communication. It is ready for multiple platforms and multiple operating systems, including:
Additional features on request:
