Abstract
Impact sounds and vibrations are an important source of information about contact interactions in haptics, robotics, and virtual reality. However, accurate estimation of their parameters for perceptually acceptable resynthesis is difficult with traditional methods. In this paper, we describe the phase-constrained estimation algorithm for estimating modes and amplitudes from impact signals. It is based on ESPRIT and least squares estimation, and produces better resynthesis results than previously used methods
