The concept of using multi-level descriptions to generate modified or modified gamut descriptions

摘要

a. A device for improving the sound field description includes: a sound field generator (100) to generate at least two sound field layer descriptions and display the sound field of at least one reference position; In addition, a metadata generator (110) is also set up to generate metadata related to the spatial information of the register, in which the register description and metadata are the enhanced description of the register. Metadata can be geometric information for each layer, such as a representative distance from a reference location.
