In any hands-free communication system where a loudspeaker and a microphone are placed in the same room, acoustic echo is a problem. A talker at the far end of the link will hear an echo from the microphone picking up the voice reproduced by the loudspeaker.
Acoustic echo is an annoying effect and can cause communication to be difficult or impossible. To overcome this problem, acoustic echo cancellation is necessary. The goal is to completely cancel the echo signal while at the same time letting the desired speech signal be transmitted.
The bdSound solution for Acoustic Echo Cancellation, bdAEC, is a robust and field-proven full-duplex algorithm that cancels echo in any hands-free communication. It is ready for multiple platforms and multiple operating systems, including:
