Abstract:
Modal synthesis methods have been investigated to synthesize virtual sounds for rigid bodies. The current methods to recreate realistic audio quality of sounding materials lack the automatic determination of satisfactory material parameters. In this study, a novel approach is introduced to estimate material parameters that capture the inherent quality of sounding materials and to extract perceptually significant features from the recorded impulse responses. A parameter estimation technique based on psychoacoustic principles is developed that incorporates material features to search the material parameters for linear modal synthesis (LMS). The synthesized audio produced from LMS preserves the same perception of material as a recorded sound. A perceptual study was also conducted and it shows that the results of this approach are well comparable with real recorded sounds in terms of perception of the materials.
