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 auditory experiment.
