Method and system for estimating parameters

An electronic device, comprising:

• at least one processor;
• and
• memory having instructions stored therein which when executed by the at least one processor causes the electronic device to:
• receive audio content,
• for a plurality of points associated with a three-dimensional (3D) sound field of the audio content, estimating a plurality of spatial parameters associated with the audio content;
• determining a region of the 3D sound field based on a comparison between the plurality of spatial parameters;
• iteratively, reducing the region of the 3D sound field and estimating new spatial parameters associated with the audio content for one or more new points in the reduced region, until one or more new spatial parameters meet or exceed a threshold, wherein each region comprises a density of new points that is higher than a density of the plurality of points of the 3D sound field;
• and
• store the one or more new spatial parameters in the memory.

A non-transitory machine-readable medium having instructions which when executed by at least one processor of an electronic device causes the electronic device to:

• for a first plurality of points associated with a three-dimensional (3D) sound field of audio content, estimate a first plurality of spatial parameters associated with the audio content;
• generate a second plurality of points in a region of the 3D sound field of the audio content based on a comparison of the first plurality of spatial parameters of the audio content, wherein the first plurality of points comprises less points than the second plurality of points;
• for the second plurality of points, estimate a second plurality of spatial parameters associated with the audio content;
• select at least one of the second plurality of spatial parameters that is greater than a remainder of the second plurality of spatial parameters or a threshold value;
• and
• store at least one of the second plurality of spatial parameters associated with the audio content.
