Abstract
It is disclosed inter alia a method comprising: determining a first sub vector comprising a first plurality of audio parameter coefficients of an audio parameter vector, quantise the first sub vector with a first quantizer to; determining a residual vector, determine a second sub vector comprising a second plurality of coefficients of the residual vector, quantising the second sub vector with a second quantizer to give a quantised second sub vector; combining the quantised second sub vector and the quantised first sub vector to give a quantized audio parameter sub vector comprising a second plurality of quantised audio parameter coefficients; and predict at least one audio parameter coefficient for a quantized audio parameter vector using the second plurality of quantised audio parameter coefficients, wherein the at least one audio parameter coefficient is a higher order audio parameter coefficient than an order of the second plurality of quantised audio parameter coefficients.
