ACOUSTIC ECHO CANCELLATION

Examples of the disclosure relate to acoustic echo cancellation using adaptive filtering modules. An apparatus for acoustic echo cancellation is configured to process a first input signal using a first acoustic echo cancellation module to obtain a first prediction signal and to process a second input signal using a second acoustic echo cancellation module to obtain a second prediction signal. The first input signal is based on a loudspeaker signal and the second input signal is a delayed first input signal. The prediction signals are processed to obtain a predicted echo signal. The predicted echo signal is applied to a received microphone signal to reduce echo from loudspeaker playback in the received microphone signal. The acoustic echo cancellation modules can be adapted using an adaptive filtering module.
