In at least one embodiment, an apparatus for generating virtual venues in a listening room in a vehicle is provided. The apparatus includes a vehicle audio controller configured to receive an incoming audio signal including entertainment data from an audio source for playback and to receive at least one captured audio signal from at least one microphone positioned in the listening room of the vehicle. The vehicle audio controller is further configured to receive a control signal indicative of a desired venue to playback the entertainment data and to adjust reverberation of at least one of the incoming audio signal and the at least one captured audio signal to playback the entertainment data in the desired venue.

An image of at least a portion of a head of a user is received. A geometry is generated of the head wearing an eyewear device based in part on the received image of the head and a geometry of the eyewear device. The geometry of the eyewear device includes a microphone array composed of a plurality of acoustic sensors that are configured to detect sounds within a local area surrounding the microphone array. A simulation is performed of sound propagation between an audio source and the plurality of acoustic sensors based on the generated geometry. An acoustic transfer function (ATF) is determined associated with the microphone array based on the simulation. The determined ATF is customized to the user, and is provided to the eyewear device of the user.

Disclosed is a method and system for diffraction-aware non-line of sight (NLOS) sound source localization (SSL) that may reconstruct an indoor space, may generate acoustic rays into the indoor space based on an audio signal collected from the indoor space, and may estimate a position of an NLOS sound source based on a point at which one of the acoustic rays is diffracted.

A device having an input that is configured to receive a sound signal captured from an acoustic environment where the device is located, is provided. The device also includes a signal processor that is configured to obtain a reverberation signature from the sound signal and classify the acoustic environment as being of a particular type in dependence on that reverberation signature. It also includes a controller configured to control an operation of the device in dependence on the classification of the acoustic environment. By using the reverberation signature to classify the environment, the device it is not dependent on a particular type of signal having to be present in the environment at the time when the sound signal is captured. The reverberation properties of the environment will be embodied by any sound signal captured from that environment.
