Abstract (en)
[origin: WO2009103610A1] The inventive method provides for an encoder in a voice codec to be designed such that after a particular idle time ("Idle Period") it recalculates the averaged energy and the autocorrelation function. Administrative points in the network inform the encoder about the idle time which has been set in the transmission network.
