Listener-position sub-band adaptive crosstalk canceller using hrtfs interpolation for immersive audio systems

The crosstalk is an undesired phenomenon that occurs in immersive systems when the sound is reproduced over two loudspeakers. In this paper, an innovative sub-band adaptive crosstalk canceller considering the listener position is proposed. Starting from a reduced set of measured head related impulse responses (HRTFs), the proposed system is composed of three parts: A listener position tracker, an HRTFs interpolation algorithm and a sub-band adaptive crosstalk canceller. In particular, the head tracking allows to obtain the listener position and the interpolator is applied to interpolate the HRTFs related to positions different from measurement points. The effectiveness of the proposed approach has been confirmed through several real-world experimental tests.
