Abstract
A solution for improving the perceived sound quality of a decoded acoustic signal is accomplished by extending the spectrum of a received narrow-band acoustic signal (a). A wide-band acoustic signal (A) is produced by extracting at least one essential attribute (z) from the narrow-band acoustic signal (a). Parameters, e.g., representing signal energies, with respect to wide-band frequency components outside the spectrum (A) of the narrow-band acoustic signal (a), are estimated based on the at least one essential attribute (z). This estimation involves allocating a parameter value to a wide-band frequency component, based on a corresponding confidence level.
