New Method for the Directional Representation of Musical Instruments in Auralizations

The issue of the representation of sound sources that vary their directional pattern in time in auralizations is introduced. Musical instruments are used as a reference for the discussion of the traditional representations with assumed fixed directional characteristics. A new method for the representation of the spatial sound contributions in time is proposed using multiple-channel recordings and various virtual sources in room auralizations. Possible developments of the proposed recording/reproduction method are described.
