Patent ID: 8428959

Claim:
An audio processing method, comprising: receiving sets of packets at an audio processing device via a network, each set having one or more of the packets, each packet having transform coefficients in a frequency domain for reconstructing an audio signal in a time domain that has undergone transform coding; Determining one or more missing packets in a given one of the sets received, the one or more missing packets sequenced in the given set with a given sequence; applying a first weight to first transform coefficients of one or more first packets in a first set sequenced before the given set, the one or more first packets having a first sequence in the first set corresponding to the given sequence of the one or more missing packets in the given set; applying a second weight to second transform coefficients of one or more second packets in a second set sequenced after the given set, the one or more second packets having a second sequence in the second set corresponding to the given sequence of the one or more missing packets in the given set; interpolating transform coefficients by summing the corresponding first and second weighted transform coefficients; inserting the interpolated transform coefficients into the given set in place of the one or more corresponding missing packets; and producing an output audio signal for the audio processing device by performing an inverse transform on the transform coefficients.
