Sound radiation simulation of musical instruments based on interpolation and filtering of multi-channel recordings

  • With the virtual environment developed here, the characteristic sound radiation patterns of musical instruments can be experienced in real-time. The user may freely move around a musical instrument, thereby receiving acoustic and visual feedback in real-time. The perception of auditory and visual effects is intensified by the combination of acoustic and visual elements, as well as the option of user interaction. The simulation of characteristic sound radiation patterns is based on interpolating the intensities of a multichannel recording and offers a near-natural mapping of the sound radiation patterns. Additionally, a simple filter has been developed, enabling the qualitative simulation of an instrument’s characteristic sound radiation patterns to be easily implemented within real-time 3D applications. Both methods of simulating sound radiation patterns have been evaluated for a saxophone with respect to their functionality and validity by means of spectral analysis and an auditoryWith the virtual environment developed here, the characteristic sound radiation patterns of musical instruments can be experienced in real-time.
