Abstract (en)
[origin: WO2006096099A1] Information (km) about excitation signals of a first signal (sm(n)) encoded by CELP is used to derive a limited set (10') of candidate excitation signals for a second correlated second signal (ss(n)). Preferably, pulse locations of the excitation signals of the first encoded signal (sm(n)) are used for determining the set (10') of candidate excitation signals. More preferably, the pulse locations of the set of candidate excitation signals are positioned in the vicinity of the pulse locations of the excitation signals of the first encoded signal (sm(n)). The first and second signals (sm(n), ss(n)) may be multi-channel signals of a common speech or audio signal. However, the first and second signals (sm(n), ss(n)) may also be identical, whereby the coding of the second signal (ss(n)) can be utilized for re-encoding at a lower bit rate.
