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: In various aspects, the disclosure provides for Enhanced Voice Services (EVS) encoding, including encoding an audio signal to obtain an encoded audio signal and a bitrate associated with the encoded audio signal; establishing a source format for the encoded audio signal based on the bitrate; reformatting the encoded audio signal with a pre-selected pattern to generate a packet, wherein a capacity of the packet is based on the source format. And, in various other aspects, the disclosure provides for EVS decoding, including obtaining a data rate associated with a packet; discarding one or more pre-selected patterns from the packet to recover an encoded audio signal based on the data rate; and decoding the encoded audio signal to generate a decoded audio signal.

Abstract: A device includes one or more processors configured to input one or more segments of an input media stream into a feature extractor. The one or more processors are further configured to pass an output of the feature extractor into an utterance classifier to produce at least one representation of at least one utterance class of a plurality of utterance classes. The one or more processors are further configured to pass the output of the feature extractor and the at least one representation into a segment matcher to produce a media output segment identifier.

Abstract: A method of capturing video includes instructing a microphone to initiate an audio scan of different areas of interest to detect audio activity. The method also includes receiving a feedback signal from the microphone in response to initiating the audio scan. The feedback signal indicates audio activity in a particular area of interest. The method further includes adjusting targeting characteristics of a device based on the feedback signal to focus the device on the particular area of interest.

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 method of controlling frame transmissions includes determining, at a first device, a frame erasure rate for a communication session between the first device and at least a second device. The method also includes comparing the frame erasure rate to an erasure threshold. The method further includes discarding an active speech frame if the frame erasure rate satisfies the erasure threshold.

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

Abstract: A device includes an encoder. The encoder is configured to receive two audio channels. The encoder is also configured to determine a mismatch value indicative of an amount of a temporal mismatch between the two audio channels. The encoder is further configured to determine, based on the mismatch value, at least one of a target channel or a reference channel. The target channel corresponds to a lagging audio channel of the two audio channels and the reference channel corresponds to a leading audio channel of the two audio channels. The encoder is also configured to generate a modified target channel by adjusting the target channel based on the offset value. The encoder is further configured to generate at least one encoded channel based on the reference channel and the modified target channel.

Abstract: A method of wireless communication includes receiving, at a first device, a reference channel and a target channel. The reference channel includes a set of reference samples, and target channel includes a set of target samples. The method also includes determining a variation between a first mismatch value and a second mismatch value. The method also includes adjusting the set of target samples based on the variation to generate an adjusted set of target samples. The method further includes generating at least one encoded channel based on the set of reference samples and the adjusted set of target samples. The method also includes transmitting the at least one encoded channel to a second device.
