Abstract: Techniques are described for coding audio signals. For example, using a neural network, a residual signal is generated for a sample of an audio signal based on inputs to the neural network. The residual signal is configured to excite a long-term prediction filter and/or a short-term prediction filter. Using the long-term prediction filter and/or the short-term prediction filter, a sample of a reconstructed audio signal is determined. The sample of the reconstructed audio signal is determined based on the residual signal generated using the neural network for the sample of the audio signal.

Abstract: A method includes decoding a low-band portion of an encoded mid channel to generate a decoded low-band mid channel. The method also includes filtering the decoded low-band mid channel according to one or more filter coefficients to generate a low-band filtered mid channel. The method also includes generating an inter-channel predicted signal based on the low-band filtered mid channel and the inter-channel prediction gain. The method further includes generating a low-band left channel and a low-band right channel based on an up-mix factor, the decoded low-band mid channel, and the inter-channel predicted signal.

Abstract: A device includes a receiver, a memory, and a processor. The receiver is configured to receive a remote voice profile. The memory is electrically coupled to the receiver. The memory is configured to store a local voice profile associated with a person. The processor is electrically coupled to the memory and the receiver. The processor is configured to determine that the remote voice profile is associated with the person based on speech content associated with the remote voice profile or an identifier associated with the remote voice profile. The processor is also configured to select the local voice profile for profile management based on the determination.

Abstract: A device includes an encoder configured to determine, during a first period, that a first audio signal is a leading signal and that a second audio signal is a lagging signal. The encoder is also configured to generate a first frame of at least one encoded signal based on a first modified version of the second audio signal that is generated by adjusting the second audio signal based on a first mismatch value. The encoder is configured to determine, during a second period, that the first audio signal is the leading signal and that the second audio signal is the lagging signal. The encoder is configured to generate a second frame of the at least one encoded signal based on a second modified version of the second audio signal that is generated by adjusting the second audio signal based on the first mismatch value and a second mismatch value.

Abstract: A device includes a processor and a transmitter. The processor is configured to determine a first value and a second value indicative of a first amount and a second amount, respectively, of a temporal mismatch between a first audio signal and a second audio signal. The processor is also configured to determine an effective value based on the first value and the second value, to select, based on the effective value, a first coding mode and a second coding mode, and to generate at least one encoded signal having a bit allocation. The at least one encoded signal is based on a first encoded signal and a second encoded signal that are based on the first coding mode and the second coding mode, respectively. The bit allocation is at least partially based on the effective mismatch value. The transmitter is configured to transmit the at least one encoded signal.

Abstract: An apparatus includes a network interface configured to receive, via a circuit-switched network, a packet. The packet includes a primary coding of a first audio frame, redundant coding of a second audio frame, and one or more bits that indicate signaling information. The signaling information corresponds to a decode operation of at least one of the primary coding or the redundant coding. The apparatus further includes a decoder configured to decode a portion of the packet based on the signaling information.

Abstract: A device includes a memory configured to store a collection of sets of weights, each of the sets of weights representing a respective media segment. The device also includes one or more processors configured to generate data representing the detected first input speech segment and to pass the data representing the detected first input speech segment into a collection of memory units. Each memory unit of the collection of memory units includes a set of weights from the collection of sets of weights. The one or more processors are also configured to generate a first estimate of an associated media segment that represents the detected first input speech segment. The associated media segment corresponds to a first memory unit in the collection of memory units.

Abstract: A method includes receiving, at an audio encoder, multiple streams of audio data. The method includes assigning a priority to each stream of the multiple streams and determining, based on the priority of each stream of the multiple streams, a permutation sequence for encoding of the multiple streams. The method also includes encoding at least a portion of each stream of the multiple streams according to the permutation sequence.
