Claim 17:
18. The decoder of claim 16, further comprising:
transforming the values of the first spectral shape and the first frame energy into the first representation of a first FFT based spectral analysis and transforming the values of the second spectral shape and the second frame energy into a second representation of a second FFT spectral analysis in accordance with

Eoold(k)=μ·shapeoold(k)·E_woold, 0≤k<Ngrp 

and

Eold(k)=μ·shapeold(k)·Ewold, 0≤k<Ngrp, where Eoold(k) is the first representation, μ is the conversion factor, shapeoold(k) is a spectral shape of a sub-band (k) of the first spectral shape, E_woold is the first frame energy, Eold(k) is the second representation, shapeold(k) is a spectral shape of a sub-band (k) f the second spectral shape, E_wold is the second frame energy, and Ngrp is the number of sub-bands.
