US 2015/0189455 A1 · TRANSFORMATION OF MULTIPLE SOUND FIELDS TO GENERATE A TRANSFORMED REPRODUCED SOUND FIELD INCLUDING MODIFIED REPRODUCTIONS OF THE MULTIPLE SOUND FIELDS

Abstract

Embodiments relate generally to electronic hardware, computer software, wired and wireless network communications, and media devices or wearable/mobile computing devices configured to facilitate production and/or reproduction of spatial audio and/or sound fields with one or more audio spaces. More specifically, disclosed are systems, devices and methods to transform multiple sound fields that include audio to form a transformed reproduced sound field, for example, for a recipient of audio in a region. In one embodiment, a method includes receiving audio streams originating from audio sources positioned in sound fields relative to corresponding reference points. Further, the method includes transforming a spatial dimension of the sound fields to form a transformed reproduced sound field. In some examples, the method also includes causing transducers to project sound beams at a point in a region at which spatial audio is produced to present the transformed reproduce sound field to an audio space.

Dependent claims

A method comprising:

receiving a first audio stream including data representing audio originating from a first subset of one or more audio sources at positions in a first sound field relative to a first reference point;
receiving a second audio stream including data representing audio originating from a second subset of one or more audio sources in a second sound field at positions relative to a second reference point;
transforming at a processor a first subset of one or more spatial dimensions of the first sound field to form a first transformed sound field;
transforming at the processor a second subset of one or more spatial dimensions of the second sound field to form a second transformed sound field;
forming a transformed reproduced sound field in which the first transformed sound field is disposed in a first portion of the transformed reproduced sound field, and the second transformed sound field is disposed in a second portion of the transformed reproduced sound field;
and
causing transducers to project sound beams at a point in a region at which spatial audio is produced to present the transformed reproduce sound field to an audio space.

A system comprising:

a media device comprising:
a housing;
a transceiver disposed in the housing and configured to communicate multiple radio frequency (“RF”) communication signals with multiple devices, the multiple RF communication signals including packets;
a plurality of transducers disposed in the housing and configured to emit acoustic signal into a region external to the housing;
a memory including executable instructions;
and
a processor configured to:
execute a first portion of the executable instructions to receive audio streams;
execute a second portion of the executable instructions to transform one or more spatial dimensions to form transformed sound fields;
execute a third portion of the executable instructions to selecting a subset of one or more parameters;
execute a fourth portion of the executable instructions to form a transformed reproduced sound field in which the transformed sound fields are disposed in portions of the transformed reproduced sound field based on the subset of the one or more parameters;
and
execute a fifth portion of the executable instructions to cause transducers to project sound beams at a point in a region to form an audio space at which spatial audio is produced to include the transformed reproduce sound fields.
