Abstract  Abstract

An improved pitch search method and device for digitally encoding a wideband signal in particular but not exclusively a speech signal in view of transmitting or storing and synthesizing this wideband sound signal. The new method and device which achieve efficient modeling of the harmonic structure of the speech spectrum uses several forms of low pass filters applied to a pitch codevector the one yielding higher prediction gain (i.e. the lowest pitch prediction error) is selected and the associated pitch codebook parameters are forwarded.
