Abstract  Abstract

An apparatus, comprising: a filter bank (A110), which contains A) a low band processing path configured to receive a broadband voice signal and to generate a low band voice signal as a function of one part low frequency of the broadband voice signal, and B) a high band processing path configured to receive the broadband voice signal and to generate a high band voice signal based on a high frequency part of the broadband voice signal, where a pass band of the low band processing path overlaps with a pass band of the high band processing path, where the overlap is considered as the distance of the point at the that the high band filter frequency response drops to -20 dB from the point where the low band filter frequency response drops to -20 dB; a first voice encoder (A120) configured to encode the low band voice signal into at least one encoded low band excitation signal and a plurality of low band filter parameters; and a second voice encoder (A200) configured to generate a high band excitation signal based on the encoded low band excitation signal and to encode the high band signal, according to the high band excitation signal, at less a plurality of high band filter parameters, characterized in that the pass band of the low band processing path overlaps with the pass band of the high band processing path between approximately 400 and 1000 Hz.
