Abstract (en)
[origin: WO0122401A1] Transmission of audio signals, partitioned into frames, between a transmitter and a receiver may induce annoying artifacts in the signal. The invention aims at reducing these artifacts in the decoded frames by derivation of a magnitude (CAL) representative of the energy and comparison of this magnitude with a derived estimate (EST). A frame is corrected (CORR) when the magnitude exceeds in a great amount the estimate (DSP).
