Recently, a method for joint extraction of pitch and location information from two-channel recordings has been introduced. This framework offers a new, natural representation of all acoustic sources in the auditory scene, and has potential to be used as front-end in applications such as advanced tracking of multiple speakers in conference rooms. In this paper, we explore basic properties of this method and propose improvements in performance by using circular arrangements of multiple microphones.
