Abstract: A method for determining an interpolation factor set by an electronic device is described. The method includes determining a value based on a current frame property and a previous frame property. The method also includes determining whether the value is outside of a range. The method further includes determining an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range. The method additionally includes synthesizing a speech signal.

Abstract: A method for mitigating potential frame instability by an electronic device is described. The method includes obtaining a frame subsequent in time to an erased frame. The method also includes determining whether the frame is potentially unstable. The method further includes applying a substitute weighting value to generate a stable frame parameter if the frame is potentially unstable.

Abstract: A device includes a receiver, a buffer, a transmitter, and an analyzer. The receiver is configured to receive a plurality of packets that corresponds to at least a subset of a sequence of packets. Error correction data of a first packet of the plurality of packets includes a partial copy of a second packet of the plurality of packets. The analyzer is configured to determine whether a particular packet of the sequence is missing from the buffer, and to determine whether a partial copy of the particular packet is stored in the buffer. The analyzer is also configured to send, via the transmitter, a retransmit message to a second device based at least in part on determining that the buffer does not store the particular packet and that the buffer does not store the partial copy of the particular packet.

Abstract: The present application relates to super wideband coding techniques to improve the quality of a synthesized high-band portion of an audio signal. This is achieved by synthesizing a high-band portion using a non-linear function selected from multiple available non-linear processing functions based on audio characteristics of a low-band portion. An adjustment parameter is also calculated based on the first extended signal, the high-band signal, or both. The selected non-linear function may improve the correlation between a high-band portion of an input signal at an encoder and the synthesized high-band portion of the output signal at the decoder in both speech and non-speech (e.g., music) situations.
