Abstract: In general, techniques are described that enable a source device to perform level estimation for processing audio data. The source device may include a memory and a processor. The memory may store at least a portion of the audio data. The processor may obtain a current indication representative of a current level of a current block of the audio data, and obtain a previous indication representative of a previous level of a previous block of the audio data. The processor may perform, based on the current indication and the previous indication, level estimation to obtain a level estimate indication representative of an estimate of the level of the current block of the audio data. The processor may also perform, based on the level estimate indication, compression with respect to the current block of the audio data to obtain a bitstream.

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.

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: In general, various aspects of techniques are described to enable application directed latency control for wireless audio streaming. A source device comprising a memory and a processor may perform the techniques. The memory may store at least a portion of audio data. The processor may execute an application that outputs the audio data, and a request for a quality of service concerning audio processing applied to the audio data. The processor may determine whether the source device is currently displaying the application, and configure, responsive to the determination that the source device is currently displaying the application, a wireless audio processing path to achieve the requested quality of service. The processor may next process, by the wireless audio processing path, the audio data to obtain a bitstream representative of the audio data.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for generating, by an encoding device, one or more entropy symbols, the length of which changes responsive to errors, stacking the entropy symbols into fixed intervals, and selecting a parity bit. The encoding device may divide entropy symbols that are longer than the fixed interval duration and stack the excess portions of the long entropy symbols with shorter entropy symbols in other intervals. The encoding device may transmit the slacked data packet according to the stacking. A decoding device may receive the data packet, identify the locations of the entropy symbols and the selected parity bit, check the parity of each entropy symbol, identify error bits based on the locations of the entropy symbols within multiple fixed intervals, and may correct error bits based on the stacked intervals, the parity bit, and an error mask.
