Generally the invention claims a technology for compressing sound site and by decomposing expression. One of including one or more of processor of the device may manage configuration for carrying out the technique. One or more of the processor can manage configuration for obtaining space component comprises the sound site and is through relative execution based on synthesis of vector generation for more then one spherical harmonic coefficient by bit stream is compression versions the space component.

In general techniques are described for compressing decomposed representations 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 obtain a bitstream comprising a compressed version of a spatial component of a sound field the spatial component generated by performing a vector based synthesis with respect to a plurality of spherical harmonic coefficients.
