SOUND SYSTEM FOR VEHICLE
20180332388 · 2018-11-15 ·

A sound system for a vehicle including an engine and an audio device for an internal space of a cabin as sound sources disposed at given positions of the vehicle is provided which includes an engine sound localizer configured to localize a first sound generated by the engine to cause a vehicle driver inside the cabin to hear the first sound from a first position, and change the first position, and a traveling state detector configured to detect a traveling state of the vehicle. The engine sound localizer normally sets the first position at a default position and, when a given traveling state is detected by the traveling state detector, changes the first position to a specific position at which the vehicle driver is able to recognize the engine sound more clearly than at the default position.

Dynamic audio optimization
10111002 · 2018-10-23 · ·

An environment detection node supports dynamic audio optimization by receiving data from sensors and analyzing the received data to detect objects such as furniture and/or humans within an environment. Based on locations within the environment of the detected objects, the environment detection node determines an optimized target location and adjusts audio output to be optimized when heard at the target location.

Methods for Determining Relative Locations of Wireless Loudspeakers

Methods, systems, and apparatuses are described for determining relative locations of wireless loudspeakers and performing channel mapping thereof. An audio processing component utilizes sounds produced by wireless loudspeakers during setup/installation procedures, which are received by a microphone at locations in an acoustic space, to determine an amount of time between when the audio signal is initially transmitted and when the microphone signal is received. The audio processing component also utilizes wireless timing signals provided by a wireless transceiver, at locations in the acoustic space, to wireless loudspeakers and then back to the wireless transceiver to determine an amount of time between transmission and reception by the wireless transceiver. The timing delays are used to determine the locations of the wireless loudspeakers in the acoustic space. Based on the determined locations, the audio processing component generates indications of correct or incorrect wireless loudspeaker placements, and performs audio channel mapping.

Optimizing the performance of an audio playback system with a linked audio/video feed

An audio system is provided that efficiently detects speaker arrays and configures the speaker arrays to output sound. In this system, a computing device may record the addresses and/or types of speaker arrays on a shared network while a camera captures video of a listening area, including the speaker arrays. The captured video may be analyzed to determine the location of the speaker arrays, one or more users, and/or the audio source in the listening area. While capturing the video, the speaker arrays may be driven to sequentially emit a series of test sounds into the listening area and a user may be prompted to select which speaker arrays in the captured video emitted each of the test sounds. Based on these inputs from the user, the computing device may determine an association between the speaker arrays on the shared network and the speaker arrays in the captured video.

Method for using a mobile device equipped with at least two microphones for determining the direction of loudspeakers in a setup of a surround sound system

A smartphone having two microphones is used for determining the direction of a loudspeaker in a surround system setup. This is performed using smartphone rotation in azimuth and polar angle direction while capturing in its microphones a test signal from a current one of the loudspeakers. From the microphone signals a corresponding TDOA value is calculated, and the smartphone is rotated until that TDOA value is nearly zero, resulting in a loudspeaker direction information.
