Abstract  Abstract

A wideband speech encoder according to one embodiment includes a filter bank having a lowband processing path and a highband processing path. The processing path has overlapping frequency response. The first encoder is configured to encode the speech signal generated by the low band processing path according to the first coding methodology. The second encoder is configured to encode the speech signal generated by the high band processing path according to a second coding methodology different from the first coding methodology.
