Abstract

MPEG-4 committee has adopted HILN as the Low Rate Parametric Audio Codec and has shown enormous potential for next generation wireless multimedia communications. HILN algorithm tracks all partials in parallel over time axis. In this article a novel partial tracking approach has been investigated and applied to extract partial trajectories in harmonic instruments. The algorithm instead of tracking all partials in parallel like HILN, records amplitude, phase and frequency information of a single partial over time. The evolving trajectories of the partials are estimated by a well known technique call Berg’s Algorithm. This novel approach has been tested with harmonic instruments having well defined non crossing partials. The algorithm acts as a framework which could incorporate other estimation techniques like Autocorrelation and Covariance method though it is beyond the scope of this paper. The scope of this paper is limited to the description of novel algorithm integrated with Berg’s approach as estimation technique. A detailed comparison of proposed algorithm with MPEG-4 HILN Low Rate Parametric Audio Codec will be presented in future research.
