Example apparatus disclosed herein compare one or more audio latency characteristics with one or more audio latency requirements in response to detection of an audio silence event, the audio latency characteristic(s) associated with at least one of a hardware layer or a device layer of an audio stack of a compute device, the audio latency requirement(s) associated with an application. Disclosed example apparatus also control a device layer of the audio stack to enter a device layer low power mode in response to a first determination that the audio latency requirement(s) is/are met by the audio latency characteristic(s). Disclosed example apparatus further control a hardware layer of the audio stack to enter a hardware layer low power mode in response to the first determination and a second determination that an operation condition for entry into the hardware layer low power mode is met.

Audio stack power control based on latency

An apparatus includes at least one memory, instructions, and processor circuitry to execute the instructions to track movement of a head of a user wearing earphones, the earphones to move with the movement of the head of the user, the earphones to be communicatively coupled to a computing device. The processor circuitry is to obtain media content, the media content including first audio data for a first channel and second audio data for a second channel. The processor circuitry is to adjust, based on the movement of the head of the user, the first audio data for the first channel and the second audio data for the second channel. The processor circuitry is to cause the adjusted first audio data and the adjusted second audio data to be played by the earphones.

Audio spatialization

Touch control surfaces for electronic user devices are disclosed herein. An example electronic device includes a microphone array and processor circuitry to detect a first acoustic event based on signals output by the microphone array, the first acoustic event indicative of a first touch on a surface of the device at a first time; detect a second acoustic event based on the signals, the second acoustic event indicative of a second touch on the surface at a second time; determine a first location of the first touch and a second location of the second touch; identify the first time and the second time as occurring within a threshold period of time; identify a gesture based on the first location, the second location, and the occurrence of the first touch and the second touch within the threshold; and cause an output at the device in response to the gesture.

Touch control surfaces for electronic user devices and related methods

Touch control surfaces for electronic user devices are disclosed herein. An example electronic device includes a microphone array, a touch event identifier to analyze signal data generated by microphones of the microphone array to detect a first touch on a surface of the electronic device, a gesture detector to correlate the first touch with a gesture, a user input mapper to map the gesture to a user input and a processor to cause the electronic device to respond to the user input.

A camera input can be used by the computer to support audio spatialization or to improve audio spatialization of an application that already supports it. A computer system may to support audio spatialization, for example, by modifying the relative latency or relative amplitude of the rendered audio packets. If a sound is intended, for example, to be located on the left side of the user, then the audio channel that is rendered on the headset speaker located on the user's left ear may have a somewhat decreased latency and increased amplitude compared to the other audio channel.

Small-scale audio speakers of various shapes are installed in parent devices. Inner casings, and the surrounding vibration-damping zone often required between such casings and the surrounding parent-device walls, are omitted from the assembly. During integration with the parent device, each un-encased speaker and its signal lines are sealed into a single-walled enclosure that incorporates a parent-device wall as at least one side. The entire interior of the single-walled enclosure becomes a back volume for the speaker. The single-walled enclosure may incorporate seals at the speaker's audio-output aperture, at the pass-through for the signal lines, and at the interface between the parent-device wall(s) and the added side(s) constituting the single-walled enclosure. Optional adhesive-free sealing options include sliding tabs held by a snap-lock latch.

Audio speakers with integrated sealing and assembly features for 'caseless' installation

Techniques are disclosed for reliably masking speech commands directed to one or more computing devices to prevent the speech commands from being rendered. In some embodiments, each of the one or more computing devices includes components configured to generate acoustic data from ambient sound waves, process the acoustic data to identify a speech command sequence, and mask the speech command sequence from being rendered. At least some of the systems and methods disclosed herein monitor inbound audio at a fine grain level of detail. Working at this level of granularity enables the system and methods described herein to detect potential speech commands early within the user's utterance thereof and to discriminate quickly between true speech commands and other user utterances. These early detection and discrimination features, in turn, enable some embodiments to manage potential communication disruptions (e.g., jitter and/or latency) by modifying rates of audio prior to rendering.

Voice command masking systems and methods

In an example, a mobile computing device is provided with mechanical driver s for enhancing audio output, including low-frequency audio. The mechanical drivers may be provided to supplement traditional speakers. In an embodiment, mechanical drivers are boosted in effectiveness by being disposed against a sturdy surface such as a desktop. When a user holds a convertible tablet up, such enhancement may be provided by enabling mechanical drivers that are disposed against a base or other structural member of the convertible tablet.

Audio enhancement in mobile computing

Camera driven audio spatialization

Adaptive filtering is described for use with amplifiers for any wired speaker. In one example, an apparatus includes an audio cable to provide an analog audio signal to an audio transducer, such as a speaker, the audio cable also receiving a modulated noise current, an output amplifier to receive an audio input, to generate an audio output by amplifying the audio input, and to provide the audio input to the audio cable, and a feedback system to receive the audio output and to receive a reference signal and to generate a noise cancellation signal to the output amplifier, the noise cancellation signal to cancel the modulated noise current.

Adaptive filtering for wired speaker amplifiers

A method and a system are described providing multiple display systems with an enhanced acoustics experience. A source audio signal having a plurality of source audio channels is generated from an audio signal source. The system includes a plurality of speakers connected to a plurality of display systems. A speaker configuration gatherer determines the spatial configuration of the speakers. An audio signal processor is provided to generate synthesized audio signal based on the contents of the source audio signal and spatial configuration of the speakers. The synthesized audio signal is mapped and delivered to the speakers to produce an enhanced sound field.
