Abstract: Encoding/decoding techniques where multiple transform parameter sets are encoded together with a rendered playback presentation of an input audio content. The multiple transform parameters are used on the decoder side to transform the playback presentation to provide a personalized binaural playback presentation optimized for an individual listener with respect to their hearing profile. This may be achieved by selection or combination of the data present in the metadata streams.

Abstract: In some implementations, a method of encoding a low-frequency effect (LFE) channel comprises: receiving a time-domain LFL channel signal; filtering, using a low-pass filter, the time-domain LFE channel signal; converting the filtered time-domain LFE channel signal into a frequency-domain representation of the LFE channel signal that includes a number of coefficients representing a frequency spectrum of the LFL channel signal; arranging coefficients into a number of subband groups corresponding to different frequency bands of the LFE channel signal; quantizing coefficients in each subband group according to a frequency response curve of the low-pass filter; encoding the quantized coefficients in each subband group using an entropy coder tuned for the subband group; and generating a bitstream including the encoded quantized coefficients; and storing the bitstream on a storage device or streaming the bitstream to a downstream device.

Abstract: Techniques described herein enable auto targeting assistance for input devices. Among a number of aspects of the present disclosure, techniques disclosed herein enable a computing device to receive a directional input signal from a wide range of input devices to select an interface element from a number of interface elements based on an arrangement of the interface elements. In some configurations, one or more angles and distances can be measured from an interface element to a vector derived from an input signal. The angles and distances can be used to select the interface element based on one or more criteria, including a weighted set of angles and distances. Auto scrolling functions can also bring a hidden interface element into a viewing area. The techniques disclosed herein can provide such functionality without requiring a UI programmer to provide complex code that associates individual interface elements for navigational purposes.

Abstract: Disclosed is a method and apparatus to help manage data communication in a manner that increases downlink capacity. As disclosed, a base station may transmit, in a downlink traffic channel of a given sub-frame, bearer data to a particular wireless communication device (WCD). After transmitting the bearer data, the base station may transmit, in the downlink control channel of another sub-frame, a signaling message that directs the particular WCD to read the previously transmitted bearer data. The signaling message may include an indication of the given sub-frame having the previously transmitted bearer data. When the WCD receives and reads the signaling message, the WCD may use the indication as a basis to read the previously transmitted bearer data in accordance with the signaling message.

A communication schedule is determined for the first access node and the second access node to communicate with the wireless device. The communication schedule can comprise a first portion and a second portion. Communication is performed between the first access node and the wireless device during the first portion, and between the second access node and the wireless device during the second portion.

Abstract: Forward and backward filters in cascade establish a specified phase shift in audio or video signals. The backward filter applies its filtering in a backward direction to impart a phase shift to its backward-filtered output that is a function of frequency. The forward filter applies its filtering in a forward direction to impart a phase shift to its forward-filtered output that has the specified phase shift relative the phase shift of the backward filter. Preferably, the two filters are recursive and are applied to signals that represent overlapping segments of the audio or video information. The overlap interval is used for filter initialization.

Abstract: This audio matrix surround decoder requires minimal digital processing, useful in portable applications, particularly in playback from a portable player using a headphone or loudspeaker virtualizer. In one embodiment it pans inputs Lt and Rt to outputs associated with front directions in response to a measure of the sum of Lt and Rt being greater than a measure of the difference between Lt and Rt, and pans Lt and Rt to outputs associated with rear directions in response to a measure of the sum of Lt and Rt being less than a measure of the difference between Lt and Rt. Lt and Rt are modified to shift the direction of reproduced signals.

Abstract: A method to process audio signals, an apparatus accepting audio signals, a carrier medium that carried instructions for a processor to implement the method to process audio signals, and a carrier medium carrying filter data to implement a filter of audio signals. The method includes filtering a pair of audio input signals by a process that produces a pair of output signals corresponding to the results of: filtering each of the input signals with a HRTF filter pair, and adding the HRTF filtered signals. The HRTF filter pair is such that a listener listening to the pair of output signals through headphones experiences sounds from a pair of desired virtual speaker locations.
