Abstract
There is inter alia disclosed an apparatus for spatial audio encoding comprising: means for determining a first spatial audio parameter of a frequency sub band of one or more audio signals and a second spatial audio parameter of the frequency sub band of the one or more audio signals; and means for combining the first spatial audio parameter and the second spatial audio parameter to provide a combined spatial audio parameter for the frequency sub band.
Claims20
An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
- determine a first spatial audio parameter of a frequency sub band of one or more audio signals and a second spatial audio parameter of the frequency sub band of the one or more audio signals;
- and
- combine the first spatial audio parameter and the second spatial audio parameter to provide a combined spatial audio parameter for the frequency sub band.
The apparatus as claimed in claim 34, wherein the apparatus is further caused to determine an ambient energy value for the frequency sub band by subtracting a first direct to total energy ratio calculated for the frequency sub band and a second direct to total energy calculated for the frequency sub band from one.
A method for comprising:
- determining a first spatial audio parameter of a frequency sub band of one or more audio signals and a second spatial audio parameter of the frequency sub band of the one or more audio signals;
- and
- combining the first spatial audio parameter and the second spatial audio parameter to provide a combined spatial audio parameter for the frequency sub band.
