Generally the invention description used for identify codebook and in compression space component and sound site when using the technology. One of including one or more of the processor device may manage configuration for carrying out the technique. One or more of the processor can configure and manage the space based on component of the whole multi-space component relative at the rest two of the multi-space component and the step of identify Huffman code book and wherein said space component to carry out compression when using said space component is through in relative multi-spherical harmonic factor of execution based on the vector then generating compound.

In general techniques are described for identifying a codebook to be used when compressing spatial components of a sound field. A device comprising one or more processors may be configured to perform the techniques. The one or more processors may be configured to identify a Huffman codebook to use when compressing a spatial component of a plurality of spatial components based on an order of the spatial component relative to remaining ones of the plurality of spatial components the spatial component generated by performing a vector based synthesis with respect to a plurality of spherical harmonic coefficients.
