Abstract
An apparatus for processing soundfield data is provided. The soundfield data defines a soundfield within a spatial reproduction region comprising at least one bright zone and at least one quiet zone. The apparatus comprises an applicator configured to apply a spatially continuously varying weighting function to the soundfield data in order to obtain weighted soundfield data defining a weighted soundfield, wherein the spatially continuously varying weighting function is configured to enhance the soundfield in at least one of the bright zone and the quiet zone.
Claims20
An apparatus for processing soundfield data, the soundfield data defining a soundfield within a spatial reproduction region comprising an at least one bright zone and an at least one quiet zone, the apparatus comprising:
- an applicator that applies a spatially continuously varying weighting function to the soundfield data to obtain a weighted soundfield data defining a weighted soundfield, wherein the spatially continuously varying weighting function enhances the soundfield in at least one of the group consisting of:
- the at least one bright zone and the at least one quiet zone;
- and
- a compressor that compresses the soundfield data based on a performance measure associated with the weighted soundfield.
A method for processing a soundfield data, the soundfield data defining a soundfield within a spatial reproduction region comprising an at least one bright zone and an at least one quiet zone, the method comprising:
- applying a spatially continuously varying weighting function to the soundfield data to obtain a weighted soundfield data defining a weighted soundfield, wherein the spatially continuously varying weighting function enhances the soundfield in the at least one of the group consisting of:
- the at least one bright zone and the at least one quiet zone;
- and
- compressing the soundfield data based on a performance measure associated with the weighted soundfield.
A non-transitory computer readable storage medium having a computer-executable instructions that, when executed by a processor, facilitate carrying out a method for processing a soundfield data, the soundfield data defining a soundfield within a spatial reproduction region comprising an at least one bright zone and an at least one quiet zone, the method comprising:
- applying a spatially continuously varying weighting function to the soundfield data to obtain a weighted soundfield data defining a weighted soundfield, wherein the spatially continuously varying weighting function enhances the soundfield in the at least one of the group consisting of:
- the at least one bright zone and the at least one quiet zone;
- and
- compressing the soundfield data based on a performance measure associated with the weighted soundfield.
