Coding an audio signals with receiving the input audio signal, splitting the input audio signal into at least two sub-bands, scaling the at least two sub-bands with a scaling factor, quantizing the scaled sub-bands using a conditional split lattice quantizer, wherein the output of the conditional split lattice quantizer is a lattice codevector for each sub-band, and encoding at least the information relating to the scaling factor and the information relating to the number of bits on which the lattice codevectors are represented.
