Abstract:
In accordance with an example embodiment of the present invention, disclosed is a method and an apparatus thereof for controlling a concealment method for a lost audio frame of a received audio signal. A method for a decoder of concealing a lost audio frame comprises detecting in a property of the previously received and reconstructed audio signal, or in a statistical property of observed frame losses, a condition for which the substitution of a lost frame provides relatively reduced quality. In case such a condition is detected, the concealment method is modified by selectively adjusting a phase or a spectrum magnitude of a substitution frame spectrum.

Claim (Index 25):
The apparatus according to  claim 15 , wherein:\n the at least one processor is operated to read the previously reconstructed signal frame from at least one memory, to perform the analyzing of the at least one of the previously reconstructed signal frame and the frame loss statistic to detect the at least one predetermined condition that could lead to suboptimal signal reconstruction quality if the first concealment method is applied; and the at least one processor is operated to read the prototype frame from the at least one memory, to perform the creating the substitution frame based on the frequency spectrum of the prototype frame, and to write the substitution frame to the at least one memory.
