Abstract

We demonstrate that damped sinusoidal modeling can be used to improve the modeling accuracy of current perceptual audio coders. We show that the model parameter estimation can be performed with TLS algorithms, and that a subband modeling approach results in TLS problems that are computationally much more tractable than the fullband approach. Experimental results indicate that subband TLS modeling can be effectively controlled using perceptual criteria.
