Generally the invention describe the technique used for determining long space component used for the sound site and compression of quantization steps. One of including one or more of a processor device may manage the configuration for carrying out the technique. Words said one or more processor may by a configuration for determining quantization to be in space component and compressing sound site when using the long step wherein said space component is through relative in a multi-spherical harmonic coefficient based on carrying out the vector then generating compound.

In general techniques are described for determining quantization step sizes for compression of spatial components of a sound field. A device comprising one or more processors may be configured to perform the techniques. In other words the one or more processors may be configured to determine a quantization step size to be used when compressing a spatial component of a sound field where the spatial component generated by performing a vector based synthesis with respect to a plurality of spherical harmonic coefficients.
