Integral Band Wise Parametric Audio Coding

Abstract: Encoder for encoding a spectral representation of audio signal (XMR) divided into a plurality of sub-bands, wherein the spectral representation (XMR) consists of frequency bins or of frequency coefficients and wherein at least one sub-band contains more than one frequency bin, the encoder comprising: a quantizer configured to generate a quantized representation (XQ) of the spectral representation of audio signal (XMR) divided into the plurality sub-bands; a band-wise parametric coder configured to provide a coded parametric representation (zfl) of the spectral representation (XMR) depending on the quantized representation (XQ)wherein the coded parametric representation (zfl) consists of parameters describing the spectral representation (XMR) in the sub-bands or coded versions of the parameters; wherein there are at least two sub-bands being different and parameters describing the spectral representation (XMR) in the at least two sub- bands being different.
