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: In a particular aspect, an apparatus includes a first network interface. The first network interface is configured to receive a packet via a packet-switched network. The packet may include a primary coding of a first audio frame and a redundant coding of a second audio frame. The apparatus further includes a processor. The processor is configured to generate a modified packet that includes one or more bits that indicate signaling information or packet decoding information. The signaling information or packet decoding information may correspond to decoding of at least one of the primary coding or the redundant coding. The apparatus further includes a second network interface configured to transmit the modified packet via a circuit-switched network.

Abstract: Un procedimiento (800) para determinar un conjunto de factores de interpolación mediante un dispositivo electrónico, comprendiendo el procedimiento: determinar, para tramas de una señal de audio, una energía de trama actual y una energía de trama anterior; determinar (806), si la relación (933) de la energía de trama actual y la energía de trama anterior está fuera de un rango, un conjunto de factores de interpolación (769, 1069, 1197a-d) basado en la relación (933) de 10 la energía de trama actual y la energía de trama anterior y un indicador de modo de predicción (1031); interpolar los vectores de frecuencia espectral de la línea de subtrama, LSF, (747) basándose en el conjunto de factores de interpolación para producir vectores LSF interpolados (751); y sintetizar (808) una señal de voz basada en los vectores LSF interpolados (751), en el que el indicador de modo de predicción es indicativo de si se utiliza una cuantificación predictiva o no predictiva para una trama.

Abstract: A method includes separating, at a device, an input audio signal into at least a low-band signal and a high-band signal. The low-band signal corresponds to a low-band frequency range and the high-band signal corresponds to a high-band frequency range. The method also includes selecting a non-linear processing function of a plurality of non-linear processing functions. The method further includes generating a first extended signal based on the low-band signal and the non-linear processing function. The method also includes generating at least one adjustment parameter based on the first extended signal, the high-band signal, or both.
