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 paths have overlapping frequency responses. The first encoder is configured to encode a speech signal produced by the lowband processing path according to the first coding methodology. The second encoder is configured to encode a speech signal produced by the highband processing path according to the second coding methodology different from the first coding methodology.
