Dynamic audio normalization process
Methods, systems, and apparatuses are described herein for improved processing audio in a video stream. A system may split audio in a frame of video content into multiple bands based on their audio levels. The system may then dynamically compress and dynamically normalize the audio level in each band. When dynamically compressing the bands, the system may determine, based on stored information, what audio level range is acceptable for an end user and may smooth and maintain the ranges of the audio to be within the acceptable range. The system may include the dynamically normalized and dynamically compressed frames as a second audio track in the video content. A computing device receiving the video content may select the second audio track during playback. If an end user selects the second audio track, the video is delivered with the modified sound of the second audio track.
METHODS AND APPARATUS FOR VOLUME ADJUSTMENT
Apparatus, systems, articles of manufacture, and methods for volume adjustment are disclosed herein. An example method includes collecting data corresponding to a volume of an audio signal as the audio signal is output through a device, when an average volume of the audio signal does not satisfy a volume threshold for a specified timespan, determining a difference between the average volume and a desired volume, and applying a gain to the audio signal to adjust the volume of the audio signal to the desired volume, the gain determined based on the difference between the average volume and the desired volume.
CANCELLATION OF SIDELINK AUTOMATIC GAIN CONTROL SYMBOL
Aspects relate to techniques for facilitating sidelink cancellation of an automatic gain control (AGC) symbol of a sidelink transmission. A network entity, such as a base station, may transmit sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The network entity may further transmit a cancellation indication indicating an overlap between an AGC symbol of time resources allocated for the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may selectively transmit the sidelink transmission.
APPARATUS AND METHOD FOR DETECTION OF BIOPOTENTIAL SIGNALS
A method and apparatus for measuring a biopotential signal together with impedance changes uses electrodes on a subject’s skin and for compensating for such impedances to increase accuracy and usability of such devices for short-and long-term monitoring of biosignals. The apparatus can include a first terminal for connection to a first electrode, a second terminal for connection to a second electrode, a first circuitry configured for measuring the biopotential signal from the first and the second terminal, a third terminal for connection to the reference skin electrode, a first variable controlled resistance load connected to the first terminal, and a second variable controlled resistance load connected to the second terminal.
Automatic volume control for combined game and chat audio
A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive audio signals. The audio processing circuitry is operable to process the audio signals to detect strength of a chat component of the audio signals and strength of a game component of the audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.
Microphone with adjustable signal processing
A microphone may comprise a microphone element for detecting sound, and a digital signal processor configured to process a first audio signal that is based on the sound in accordance with a selected one of a plurality of digital signal processing (DSP) modes. Each of the DSP modes may be for processing the first audio signal in a different way. For example, the DSP modes may account for distance of the person speaking (e.g., near versus far) and/or desired tone (e.g., darker, neutral, or bright tone). At least some of the modes may have, for example, an automatic level control setting to provide a more consistent volume as the user changes their distance from the microphone or changes their speaking level, and that may be associated with particular default (and/or adjustable) values of the parameters attack, hold, decay, maximum gain, and/or target gain, each depending upon which DSP is being applied.
Playback device group volume control
Embodiments are provided for satellite volume control. An example method includes receiving an input at a playback device to adjust a volume for a plurality of playback devices that are grouped for synchronous playback of audio content, wherein the plurality of playback devices includes the playback device. The method also includes sending a first message over a network from the playback device to a device associated with the plurality of playback devices, the first message including information based on the input, wherein the information is used to adjust the volume of the plurality of playback devices. The method also includes receiving a second message at the playback device over the network, the second message including information for the volume of the playback device, wherein the volume is based on the adjusted volume of the plurality of playback devices.

An example method includes collecting data corresponding to a volume of an audio signal as the audio signal is output through a device, when an average volume of the audio signal does not satisfy a volume threshold for a specified timespan, determining a difference between the average volume and a desired volume, and applying a gain to the audio signal to adjust the volume of the audio signal to the desired volume, the gain determined based on the difference between the average volume and the desired volume.
DIGITAL VARIABLE GAIN ADJUSTMENT ON BASEBAND CHIP
Embodiments of apparatus and method for digital variable gain adjustment (DVGA) are disclosed. In an example, a baseband chip includes an unpacking module, a symbol recording module operatively coupled to the unpacking module, and a first variable gain adjusting (VGA) module operatively coupled to the symbol recording module. The unpacking module is configured to unpack a plurality of symbols from a first representation of pseudo floating-point numbers to a second representation of fixed-point numbers. The symbol recording module is configured to obtain a symbol parameter based on the unpacking. The first VGA module is configured to dynamically adjust gains of the plurality of symbols having the second representation based on the symbol parameter.
DELAY ADJUSTMENT CIRCUITS
Methods, systems, and devices for delay adjustment circuits are described. Amplifiers (e.g., differential amplifiers) may act like variable capacitors (e.g., due to the Miller-effect) to control delays of signals between buffer (e.g., re-driver) stages. The gains of the amplifiers may be adjusted by adjusting the currents through the amplifiers, which may change the apparent capacitances seen by the signal line (due to the Miller-effect). The capacitance of each amplifier may be the intrinsic capacitance of input transistors that make up the amplifier, or may be a discrete capacitor. In some examples, two differential stages may be inserted on a four-phase clocking system (e.g., one on 0 and 180 phases, the other on 90 and 270 phases), and may be controlled differentially to control phase-to-phase delay.
