Techniques for automatic equalization of audio
In various embodiments, the disclosed techniques automatically change the audio equalization levels of audio content. When an audio content is requested for playback, the equalization manager of an audio system extracts the frequency components of a segment of the audio content. The equalization manager analyzes the frequency components of the segment and separates the frequency components into predefined frequency bands based on the analysis. The equalization manager determines sound pressure level (SPL) metrics of each frequency component. The equalization manager generates a custom equalization setting using gains calculated for each frequency band based on the SPL metrics. The equalization manager then adjusts the audio segment by applying the custom equalization setting to generate a modified segment (e.g., applying the calculated gains to each of the frequency bands). The modified segment is then output as audio to a user. The process then repeats for additional segments of the audio.

Method for reducing errors in an ambient noise compensation system
Some noise compensation methods involve: receiving a microphone signal corresponding to ambient noise from a noise source location in or near an audio environment; determining or estimating a listener position in the audio environment; and estimating at least one critical distance, the critical distance being a distance from the noise source location at which the directly propagated sound pressure equals the diffuse-field sound pressure. Some examples involve estimating whether the listener position is within the at least one critical distance, and performing the noise compensation method for the ambient noise based at least in part on the estimation of whether the listener position is within the critical distance.

Altering audio to improve automatic speech recognition
Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.

Display device and audio control method thereof
PendingEP4539476A1Television system detailsManually-operated gain controlComputer hardwareLower limit
A display device capable of providing a first audio, which is coupled to a host device through a first interface, performs the following operations. A first output volume value of the display device is adjusted according to a first control command, and the first output volume value is compared with an upper limit value or a lower limit value to generate a first comparison result. The first audio is generated according to the first output volume value and a second output volume value of the host device. When the first control command indicates increasing or decreasing the first output volume value, and the first comparison result indicates that the first output volume value is equal to the upper limit value or the lower limit value, a second control command is sent to the host device through the first interface to adjust the second output volume value.

Processes and systems for headphone tuning
PCT designated stage expiredWO2025129204A1Headphones for stereophonic communicationSpeech analysisHeadphonesAudio frequency
The processes and systems for tuning headphones includes analyzing a baseline audio profile for a lower range reference frequency and a midrange reference frequency, and adjusting an amplitude of the lower range reference frequency to equal that of an amplitude of the midrange reference frequency. A user-interactable interface works in conjunction with the headphones to generate a tone at the adjusted amplitude of the lower range reference frequency and a tone at an initial amplitude of a midrange tuned frequency from a user sound profile so the user can hear the differences in amplitudes. Thereafter, the user modifies the initial amplitude of the midrange tuned frequency within the user sound profile by a discrepancy value based on the difference between the adjusted amplitude of the lower range reference frequency and the initial amplitude of the midrange tuned frequency so the user sound profile better corresponds to the baseline audio profile.

Sound processing apparatus and sound processing system
The present technology relates to a sound processing apparatus and a sound processing system for enabling more stable localization of a sound image.A virtual speaker is assumed to exist on the lower side among the sides of a tetragon having its corners formed with four speakers surrounding a target sound image position on a spherical plane. Three-dimensional VBAP is performed with respect to the virtual speaker and the two speakers located at the upper right and the upper left, to calculate gains of the two speakers at the upper right and the upper left and the virtual speaker, the gains being to be used for fixing a sound image at the target sound image position. Further, two-dimensional VBAP is performed with respect to the lower right and lower left speakers, to calculate gains of the lower right and lower left speakers, the gains being to be used for fixing a sound image at the position of the virtual speaker. The values obtained by multiplying these gains by the gain of the virtual speaker are set as the gains of the lower right and lower left speakers for fixing a sound image at the target sound image position. The present technology can be applied to sound processing apparatuses.

In various embodiments, a sound modification application selectively modifies one or more sounds included in one or more audio signals. In operation, the sound modification application determines classifications associated with multiple sounds included in one or more audio signals. The sound modification application selects a first frequency sub-band of a first sound included in the multiple sounds based on a first classification associated with the first sound. The sound modification application then modifies the first frequency sub-band of the first sound, without modifying at least a second frequency sub-band of the first sound, to generate a modified audio signal.
