SOUND CAPTURE FOR MOBILE DEVICES
20230055257 · 2023-02-23 ·

Audio signals from microphones of a mobile device are received. Each audio signal is generated by a respective microphone of the microphones. First microphones are selected from among the microphones to generate a front audio signal. Second microphones are selected from among the microphones to generate a back audio signal. A first audio signal portion, which is determined based at least in part on the back audio signal, is removed from the front audio signal to generate a modified front audio signal. A second audio signal portion is removed from the modified front audio signal to generate a left-front audio signal. A third audio signal portion is removed from the modified front audio signal to generate a right-front audio signal.

11508391 · 2022-11-22 ·

A voice enhancing device amplifies and clarifies the voice of a user with hypophonia or other voice issues. The device includes a collar of either rigid or a soft material that is shaped to comfortably sit on the shoulders of the user. One or more microphone arrays are adjustably mounted to the collar to capture audio of the user talking. An electronics module enhances the captured audio signal and generates an enhanced audio signal that drives at least one speaker adjustably attached to the collar. The electronic controller implements one or more of an AGC amplifier to correct amplitude variation in spoked words, adaptive filtering to actively filter out background noise, a variable attack and decay function to improve intelligibility of the spoken words, a diphthong modification function to clarify the spoken words, and an echo cancelation function to reduce echo and feedback in the enhanced audio.

AUDIO APPARATUS AND METHOD OF OPERATION THEREFOR

An audio apparatus, e.g. for rendering audio for a virtual/ augmented reality application, comprises a receiver (201) for receiving audio data for an audio scene including a first audio component representing a real-world audio source present in an audio environment of a user. A determinator (203) determines a first property of a real-world audio component from the real-world audio source and a target processor (205) determines a target property for a combined audio component being a combination of the real-world audio component received by the user and rendered audio of the first audio component received by the user. An adjuster (207) determines a render property by modifying a property of the first audio component indicated by the audio data for the first audio component in response to the target property and the first property. A renderer (209) renders the first audio component in response to the render property.

The present invention contributes to reducing the burden on a user while preventing speeches translated into a plurality of languages from interfering with each other. A translation system comprises a camera that obtains surroundings information; a directional speaker that is movable so as to output sound toward a specified position; a directional microphone that is movable so as to receive sound from a specified position; and a translation apparatus that determines a location of a user from the surroundings information obtained by the camera, moves the directional speaker and the directional microphone toward the location of the user, identifies the language of a speech received by the directional microphone, translates the language into another language to output the translated language from another directional speaker, and retranslates the translation in the another language into the language to output the retranslated language from the directional speaker.

Audio device for a vehicle and method for operating an audio device for a vehicle

An audio device for a vehicle includes a loudspeaker system having a plurality of loudspeakers, which are arranged spatially such that they enable a three-dimensional listening experience in a vehicle interior. The audio device also includes a control unit which is coupled to the loudspeaker system and which is configured to control at least one loudspeaker of the loudspeaker system in order to reproduce a position-specific warning signal which is linked to a specific position. For reproducing the position-specific warning signal, the control unit controls only the loudspeaker or those loudspeakers of the loudspeaker system which is/are closest to the specific position.

A method of presenting audio comprises: identifying a first ear listener position and a second ear listener position in a mixed reality environment; identifying a first virtual sound source in the mixed reality environment; identifying a first object in the mixed reality environment; determining a first audio signal in the mixed reality environment, wherein the first audio signal originates at the first virtual sound source and intersects the first ear listener position; determining a second audio signal in the mixed reality environment, wherein the second audio signal originates at the first virtual sound source, intersects the first object, and intersects the second ear listener position; determining a third audio signal based on the second audio signal and the first object; presenting, to a first ear of a user, the first audio signal; and presenting, to a second ear of the user, the third audio signal.

METHOD OF USING STEREO RECORDING TO CONTROL THE FLASHING OF CENTRAL LAMPS
20220369443 · 2022-11-17 ·

A method of using stereo recording to control the flashing of central lamps includes the steps of: providing left and right channel microphones in a stereo sound source venue or electronic device, and recording the plural sound sources generated by the left area, central area and right area of the stereo sound source, then storing the recorded analog signal in an audio signal sampling unit of a signal processing device, and then converting the sound signal into a light flashing formula to obtain a light flashing parameter value. According to the light flashing parameter value of the operation control unit, the left side lamps, the central lamps and the right side lamps respectively form staggered flashing, so that the flashing light set produces light changes corresponding to the music rhythm and vocals.

Autonomous gating selection to reduce noise in direct time-of-flight depth sensing

A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.
