Encoding And Decoding Of Acoustic Environment

Abstract: There are disclosed apparatus and methods for encoding and decoding of acoustic environment. In accordance to an example, there is provided an apparatus for decoding an acoustic environment, the acoustic environment including at least one audio source and at least one audio object, the at least one audio object being represented by a structural-acoustic data which links positional data of polygons with acoustic properties of acoustic materials, wherein the positional data includes, for each polygon, the position of the vertexes, the apparatus comprising: a bitstream reader for reading, from the bitstream, an encoded version of structural-acoustic data and at least one audio stream to be rendered as generated by the at least one audio source in the acoustic environment; an audio source decoding block to decode the at least one an audio stream representing the at least one audio source; a structural-acoustic data decoding block to decode the structural-acoustic data.
