Abstract

A system may be configured to: receive remote audio signals and corresponding spatial indicators from remote systems; generate output signals for local speakers based on the remote audio signals and the corresponding spatial indicators; supply a microphone input signal to a first echo canceller in a series of echo cancellers, where each echo canceller of the series corresponds to a position in a set of positions along a one-dimensional locus connecting the speakers; map each of the remote audio signals to a corresponding one of the positions based on the corresponding spatial indicator; for each position of the set of positions, combine any of the remote audio signals that map to that position in order to form a corresponding input signal for the corresponding echo canceller; transmit a resultant signal including at least an output of a last echo canceller of the series to the remote systems.
