Abstrakt

This article presents a system for estimation of the direction of multiple speakers and zooming the sound of one of them. The proposed system is combined of two levels; namely, sound source direction estimation and acoustical zooming. The sound source direction estimation uses so-called the energetic analysis method for estimation of the direction of multiple speakers, whereas the acoustical zooming is based on modifying the parameters of the directional audio coding (DirAC) in order to zoom the sound of a selected speaker among the others. Listening tests are performed in order to evaluate this system using different time-frequency transforms.

Klíčová slova

Acoustical zooming, spatial sound, vector base amplitude panning, sound source localization, energetic analysis method, directional audio coding.
