Abstract
An apparatus comprising means configured to: obtain at least one audio signal; determine at least one direction parameter of at least one propagating sound associated with the at least one audio signal; determine at least one direction of at least one sound source associated with the at least one audio signal; modify the at least one direction parameter in accordance with the determined at least one direction; and output the modified at least one direction parameter.
Claims20
An apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- obtain at least two audio signals captured by one or more microphones of a device;
- determine at least one direction of arrival parameter associated with at least one sound source of a sound field based on the at least two audio signals, wherein the at least one direction of arrival parameter at least in part represents a spatial impression of the at least one sound source within the sound field;
- receive information provided by a sensor of the device;
- determine at least one direction of the at least one sound source of the sound field based on the information provided by the sensor;
- modify the at least one direction of arrival parameter in accordance with the determined at least one direction;
- and
- output the modified at least one direction of arrival parameter.
A method comprising:
- obtain at least two audio signals captured by one or more microphones of a device;
- determining at least one direction of arrival parameter associated with at least one sound source of a sound field based on the at least two audio signals, wherein the at least one direction of arrival parameter at least in part represents a spatial impression of the at least one sound source within the sound field;
- receiving information provided by a sensor of the device;
- determining at least one direction of the at least one sound source of the sound field based on the information provided by the sensor;
- modifying the at least one direction of arrival parameter in accordance with the determined at least one direction;
- and
- outputting the modified at least one direction of arrival parameter.
