Patent ID: 7321851

Claim:
A method for manipulating a received sound signal to produce a sound signal, wherein the received sound signal is received from a packet-switched network that loses some packets, the method comprising steps of: receiving a first received frame from the packet-switched network, wherein: the first received frame is part of the received sound signal, and the packet-switched network has packet loss; producing a first signal frame corresponding to the first received frame, wherein: the first signal frame is part of the sound signal, and a second received frame is normally produced contiguously with the first received frame; determining after beginning the first-listed producing step that the second received frame is currently unavailable for production; and producing an expanded portion after the determining step, wherein: the first signal frame and the expanded portion are contiguous parts of the sound signal, the expanded portion corresponds to a different amount of the received sound signal than either the first or second received frames, and the first signal frame and the expanded portion have different time lengths in the sound signal.
