Method for measuring violin sound radiation based on bowed glissandi and its application to sound synthesis130(2011); http://dx.doi.org/10.1121/1.3605291View Description Hide Description
This work presents a method for measuring and computing violin-body directional frequency responses, which are used for violinsound synthesis. The approach is based on a frame-weighted deconvolution of excitation and response signals. The excitation, consisting of bowedglissandi, is measured with piezoelectric transducers built into the bridge. Radiation responses are recorded in an anechoic chamber with multiple microphones placed at different angles around the violin. The proposed deconvolution algorithm computes impulse responses that, when convolved with any source signal (captured with the same transducer), produce a highly realistic violinsound very similar to that of a microphone recording. The use of motion sensors allows for tracking violin movements. Combining this information with the directional responses and using a dynamic convolution algorithm, helps to improve the listening experience by incorporating the violinist motion effect in stereo.
