DESCRIPTION:The problem of finding the fundamental frequency of a periodic
  waveform is important in many speech and audio processing systems with ap
 plications ranging from analysis and compression to separation and enhance
 ment. In this talk\, some new results on fundamental frequency estimation 
 will be presented. Specifically\, it will be shown how the subspace orthog
 onality property of the MUSIC algorithm can be used to estimate the fundam
 ental frequency and the number of harmonics jointly. Also\, the extension 
 of the method to multiple periodic signals will be covered and ongoing res
 earch will be discussed.
