Audio conferencing systems and methods with mutual adaptation control of adaptive beamforming and adaptive acoustic echo cancellation are disclosed. Mutual adaptation control may be achieved in a system including an adaptive beamforming module, an adaptive acoustic echo cancellation module, and an adaptation control module. The adaptive beamforming module has a controllable beamforming adaptivity and a beamforming adaptation state. The adaptive acoustic echo cancellation module has a controllable AEC adaptivity and an AEC adaptation state. The adaptation control module is configured and/or operates (i) to modify the beamforming adaptivity when the AEC adaptation state is unsettled (adapting to changed conditions), (ii) to modify the AEC adaptivity when the beamforming adaptation state is unsettled (adapting to changed conditions), (iii) to restore the beamforming adaptivity when the AEC adaptation state is settled, and (iv) to restore the AEC adaptivity when the beamforming adaptation state is settled.
