Abstract
A device includes a memory and one or more processors. The memory is configured to store instructions. The one or more processors are configured to execute the instructions to obtain electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head. The one or more processors are also configured to execute the instructions to render, based on the electrical activity data, audio data to adjust a location of a sound source in a sound field during playback of the audio data.
Claims30
A device comprising:
- one or more processors configured to:
- obtain electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head during a first playback operation of audio data;
- determine, based on the electrical activity data, a user preferred location of a sound source in a sound field;
- and
- render, based on the user preferred location of the sound source, audio data to adjust a location of the sound source in the sound field during a second playback operation of the audio data.
A method comprising:
- obtaining, at a device, electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head;
- processing the electrical activity data using a machine learning model to determine a user gaze estimate;
- updating, based on the user gaze estimate, an estimated location of the user relative to a reference;
- and
- rendering, based at least in part on the estimated location of the user relative to the reference, audio data to adjust a location of a sound source in a sound field during playback of the audio data.
A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
- obtain electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head;
- process the electrical activity data using a machine learning model to determine a user preferred location of a sound source in a sound field;
- and
- render, based at least in part on the user preferred location, audio data to adjust a location of the sound source in the sound field during playback of the audio data.
An apparatus comprising:
- means for rendering audio data to include a first location of a speech source and a second location of a non-speech source in a sound field during a first playback operation of the audio data;
- means for obtaining electrical activity data corresponding to electrical signals from one or more electrical sources within a user's head during the first playback operation;
- means for determining, based on the electrical activity data, a user preferred location of a sound source in the sound field;
- and
- means for rendering, based at least in part on the user preferred location, the audio data to adjust a location of the sound source in the sound field during a second playback operation of the audio data.
