Abstract
A method of audio signal processing is described. The method includes calculating a criticality measure based on information about a first frame of the audio signal. The method also includes calculating a threshold value based on information relating to a state of a transmission channel. The method further includes comparing the calculated criticality measure to the calculated threshold value. The method additionally includes deciding to transmit a redundant copy of the first frame based on a result of the comparison. The method also includes transmitting the redundant copy of the first frame with a second frame. The first frame precedes the second frame in the audio signal.
