A first device includes a memory configured to store instructions and one or more processors configured to receive audio signals from multiple microphones. The one or more processors are configured to process the audio signals to generate direction-of-arrival information corresponding to one or more sources of sound represented in one or more of the audio signals. The one or more processors are also configured to and send, to a second device, data based on the direction-of-arrival information and a class or embedding associated with the direction-of-arrival information.

A sound signal processing method includes: receiving a line-inputted sound signal; controlling a volume of the line-inputted sound signal; and generating an early reflected sound control signal using the line-inputted sound signal having the controlled volume.

An illustrative collaboration space provider system provides a virtual collaboration session that allows for audio communication between a user and one or more other users virtually located within a virtual collaboration space. The user is represented by an avatar located at an avatar location within the virtual collaboration space. The collaboration space provider system receives user input from the user, the user input representative of a voice origination location that is within the virtual collaboration space and is distinct from the avatar location. During the virtual collaboration session, the collaboration space provider system simulates propagation within the virtual collaboration space of a voice communication spoken by the user. The propagation of the voice communication is simulated to originate from the voice origination location and not from the avatar location. Corresponding methods and systems are also disclosed.

A speaker system includes a first speaker and a second speaker. The first speaker includes a first sound signal input interface configured to acquire a first sound signal, and a first sound emitter configured to output a first sound based on the first sound signal in a state in which a position of a host device is fixed. The second speaker includes a second sound signal input interface configured to acquire a second sound signal, a moving body that includes a position information acquisition interface configured to acquire information relating to position and that is configured to move based on the information relating to position, and a second sound emitter configured to output a second sound based on the second sound signal.

Techniques described herein include generating first audio signals representative of sounds emanating from an environment and captured with an array of microphones disposed within an ear-mountable listing device. A rotational position of the array of microphones is determined. A rotational correction is applied to the first audio signals to generate a second audio signal. The rotational correction is based at least in part upon the determined rotational position. A speaker of the ear-mountable listening device is driven with the second audio signal to output audio into an ear.

In at least one embodiment, a loudspeaker arrangement for a vehicle is provided. The loudspeaker arrangement includes a surround sound loudspeaker arrangement and at least one proximity woofer. The surround sound loudspeaker arrangement includes a plurality of surround woofers being positioned in a listening environment in the vehicle that defines a plurality of sounds zones to provide a first low frequency audio output having a first sound pressure level within the vehicle. The at least one proximity woofer is positioned about a first seat in a first sound zone of the vehicle, the at least one proximity woofer being configured to provide a second low frequency audio output in the first sound zone of the vehicle. The second low frequency audio output as provided by the at least one proximity woofer modifies the first sound pressure level to provide a target sound pressure level.

A plurality of control points (10) are defined which each have a known spatial relationship relative to an array of transducers. An amplitude is assigned to each control point (12). A matrix (16) is produced containing elements which represent, for each of the control points, the effect that producing a modeled acoustic field having the assigned amplitude with a particular phase at the control point has on the consequential amplitude and phase of the modeled acoustic field at the other control points (14). Eigenvectors of the matrix (18) are determined, each eigenvector representing a set of phases and relative amplitudes of the modeled acoustic field at the control points. One of the sets (20) is selected and the transducer array is operated to cause one or more of the transducers to output an acoustic wave each having an initial amplitude and phase such that the phases and amplitudes of the resultant acoustic field at the control points correspond to the phases and relative amplitudes of the selected set (22, 24).

Disclosed is a device for processing an audio signal, which renders an audio signal. The device for processing an audio signal includes a processor. The processor receives metadata including an audio signal and first element reference distance information and renders a first element signal on the basis of the first element reference distance information, wherein the first element reference distance information indicates the reference distance of an element signal. The audio signal is capable of including a second element signal which may be simultaneously rendered with the first element signal, and the metadata is capable of including second element distance information indicating the distance of the second element signal. The number of bits required for representing the first element reference distance information is smaller than the number of bits required for representing the second element distance information.

A method (900) for representing a cluster of audio objects (202). The method includes obtaining (s902) reference position information identifying a reference position within the cluster of audio objects; and using the obtained reference position information, transforming (s904) the cluster of audio objects into a composite spatial audio object. The transforming of the cluster of audio objects into the composite spatial audio object is performed independently of any listening position of any user.

Systems and methods for generating sound elements in a vehicle are present. In one example, a method comprises selecting a sound element, the sound element corresponding to a natural environment; and broadcasting the sound element via one or more speakers of a vehicle. In this way, a sound environment may be provided to a vehicle user based on the at least one vehicle state.
