Abstract: A stereo audio output signal is obtained based on position information indicative of a position of a participant of a teleconference relative to a plurality of audio output devices, wherein both the participant and the plurality of audio devices are located within a teleconferencing space. Playback of the stereo audio output signal is caused at the plurality of audio output devices located within the teleconferencing space. An audio input signal captured at an audio capture device located within the teleconferencing space is received, wherein at least a portion of the audio input signal comprises audio caused by playback of the stereo audio output signal by the plurality of audio output devices. The position information is used to perform an Acoustic Echo Cancellation (AEC) process to the at least the portion of the audio input signal.
