Seamless Spatial Calibration of Multichannel Sound Systems

In a multichannel audio setup, spatial calibration aims at delivering an optimal sound experience at the listening position. Since the listener is not expected to stand at the focal point between the surrounding speakers, usually arbitrarily placed, it is needed to focus the sweet spot at the listening position. To do so, proper gains and delays need to be applied to each channel composing the audio setup. The work presented in this paper provides a solution to automatically estimate and apply these parameters. It is based on joint user and speaker localization in a seamless way thanks to microphones embedded in surrounding speakers. A patent is currently pending for the spatial calibration method described in this paper.
