Claim Text:
1. A system for concatenating a first frame of samples and a subsequent second frame of samples in a digitized audio signal in a receiver, the system comprising: one or more processor; and one or more computer-readable memories, coupled to the one or more processors, comprising instructions executable by the one or more processors to configure the system to: generate concealment samples from the subsequent second frame of samples of the digitized audio signal; place the concealment samples in the signal such that the second frame follows the concealment samples; initialize a parametric all pass filter in the receiver based on said concealment samples, thereby initializing filter coefficients of the parametric all pass filter; and concurrently apply the parametric all pass filter to at least part of samples in at least two consecutive frames, so as to minimize a discontinuity at a boundary between the first and second frames of samples.
