Abstract:
1. A method of minimizing artifacts in speech, said method comprising performing each of the following acts within a device that is configured to process audio signals: detecting that an expected frame of a signal being decoded is absent from a buffer; based on a phase of the decoded signal at the expected frame, obtaining a phase for matching; and decoding a received frame that is subsequent in the signal to the expected frame, wherein said decoding the received frame comprises one among (A) increasing the number of samples in the frame as decoded, based on the phase for matching, and (B) decreasing the number of samples in the frame as decoded, based on the phase for matching; wherein said one among increasing and decreasing the number of samples of said frame as decoded comprises decoding said frame at an offset from a beginning of said frame, such that a first sample of the decoded frame is phase-matched to the phase for matching, and wherein the phase for matching is based on a phase at the end of a decoded frame that is prior to the expected frame.
