Abstract: A device includes one or more processors configured to execute instructions to obtain, at a first audio output device, first spatial audio data and a first reference time associated, and to cause the first reference time and data representing at least a portion of the first spatial audio data to be transmitted from the first audio output device. The instructions further cause the one or more processors to receive, at the first audio output device from a second audio output device, second spatial audio data and a second reference time. The instructions further cause the one or more processors to, based on the first reference time and the second reference time, time-align the first spatial audio data and the second spatial audio data to generate combined audio data representing a three-dimensional (3D) sound field and to generate audio output based on the combined audio data.

Abstract: Methods, devices, non-transitory computer-readable medium, and systems are described for compressing audio data. The techniques involve obtaining a sequence of digitized samples of an audio signal, performing a transform using the sequence of digitized samples, to generate a plurality of spectral lines, obtaining a group of spectral lines from the plurality of spectral lines, and quantizing the group of spectral lines to generate a group of quantized values. Quantizing the group of spectral lines to generate the group of quantized values may comprise performing a specialized rounding operation on a spectral line selected from the group of spectral lines and using the specialized rounding operation to force a group parity value, computed for the group of quantized values, to a predetermined parity value. One or more data frames based on the group of quantized values may be outputted.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless audio system, a first wireless device may generate a first media stream associated with a first media mode and a second media stream associated with a second media mode, buffer the first media stream in accordance with a first latency time value for adjusting a first latency time of the first media stream and buffering the second audio stream, independently from the first media stream, in accordance with a second latency time value for adjusting a second latency time of the second media stream, and transmit a mixed media stream including the buffered first media stream mixed with the buffered second media stream to a second wireless device.

Abstract: Methods, systems, and devices for techniques for dynamically adjusting retransmission opportunities within a connected isochronous stream (CIS) are described. In some aspects, a first wireless device and a second wireless device may support one or more dynamic or “on-the-fly” adjustments to one or more CIS settings in accordance with a link quality between the first wireless device and the second wireless device. For example, the first wireless device and the second wireless device may tie a number of transmission opportunities that are usable for retransmissions, within a given isochronous (ISO) interval, to the link quality between the first wireless device and the second wireless device. The link quality may be tied or associated with a modulation and coding scheme (MCS) of the link. As such, the first wireless device and the second wireless device may tie a dynamic change in MCS to a dynamic change in retransmission opportunities.

Abstract: This disclosure provides methods, components, devices and systems for low-latency parameter updates. In some aspects, a wireless communication device, such as a handset or an access point (AP), may transmit, to one or more wireless audio devices, an indication of a set of updated parameters associated with an extended personal area network (XPAN) of the wireless communication device. The wireless communication device may embed the indication of the set of updated parameters via a real-time protocol (RTP) header or in a padding section of a payload data of an audio data packet. A wireless audio device may extract the set of updated parameters from the audio data packet and may transmit an acknowledgement (ACK) to the wireless communication device. As a result of receiving an ACK from the wireless audio device(s), the wireless communication device may communicate with the wireless audio device(s) in accordance with the updated parameters.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques generally provide for modifying a bit rate of a real-time stream at a station (STA). The STA may determine an average wake duration within an interval for communications with an access point (AP), and may compare the average to a target active duration for efficient power usage. In some other cases, the STA may learn a scheduling pattern of the AP, and may reduce the bitrate to eliminate the need for a portion of the wake duration having relatively lower data transmissions. Modifying the bit rate may support adjusting the active duration of the STA to be closer to the target active duration while maintaining a similar quality of the real-time stream (such as, a lossless stream).

Abstract: Examples herein include apparatus and methods for overriding a media access control module acknowledgment and non-acknowledgment scheme. In one example, a codec module determines if an error-corrected packet is acceptable in response to the detection by the media access module of an uncorrectable error in a received packet, and overrides the media access control module to prevent a non-acknowledgment response from being sent when the error-corrected packet is acceptable.

Abstract: A source device comprising a memory and a processor may be configured to perform techniques described in this disclosure. The memory may store at least a portion of the audio data. The processor may obtain, from a compressed version of the audio data, a symbol, and obtain a plurality of intervals, each having a same bit length. The processor may obtain a portion of the symbol within the bit length and an excess portion of the symbol over the bit length, and specify, in a first interval, the portion of the symbol. The processor may also specify, in a second interval, the excess portion of the symbol, and apply, to the first interval and the second interval, error resiliency. The processor may specify, in a bitstream representative of the compressed version of the audio data, the first error resilient interval and the second error resilient interval.
