Abstract:
1. A conference device, comprising: a plurality of monaural HRTF filters each HRTF filter allocated to a different conference participant, each filter for filtering an input monaural audio signal, an output of the monaural HRTF filter comprising an output monaural audio signal, wherein each monaural HRTF filter comprises a different monaural HRTF filter coefficient set for defining filter characteristics of that filter and each filter coefficient set is configured to provide a different directional auditory impression that virtually positions each one of the allocated conference participants in a different direction relative to a median plane; and a conference mixing device coupled to the HRTF filters for mixing the output monaural audio signal of different conference participants and for transferring the mixed audio monaural signals to conference participants over a communications system such that the transferred monaural signals provide a different directional auditory impression that virtually positions each one of the allocated conference participants in a different direction relative to the median plane.
