Equipment and methods for space audio encoding

Abstract

The invention relates to a device and method for spatial audio encoding. This spatial audio encoder is configured to convert two or more energy ratios associated with the frequency-time slices of one or more audio signals against another energy ratio parameter associated with two or more energy ratios; the magnetization of the other energy ratio parameter uses the first magnetization; Determine the distribution coefficient of the energy ratios depending on the ratio of the first of two or more energy ratios to the sum of two or more energy ratios; select a different quantizer from several other quantizers using a different quantized energy ratio parameter; and quantize the distribution coefficient of the energy ratios using the selected different quantizer.
