Extremely fast convergence rates of 49dB/sĮXAMPLE: BASIC CONFERENCING WITH LOCAL SOUND REINFORCEMENT.Adaptive (Speech Passing) Non-Linear Processing.It can then apply that transfer function to the received signal and correctly subtract the modified original signal.Įach Soundweb London AEC input card consists of four AEC input channels.Įach channel offers the following features: To subtract the unwanted signal correctly, the Acoustic Echo Cancellation (AEC) processor needs to simulate the dynamic room transfer function. This transfer function is also dynamic as objects in the room move or the microphone moves position. These effects are the result of the transfer function of the room. This may include differing signal paths causing reverb, frequency filtering and attenuation. The received far-side signal does not transfer directly from the speaker to the microphone, but is subject to the artifacts of the room. This transmitted signal is a delayed version of the original, which causes the echo.
