1. A method for encoding of an audio signal, the method comprising:
obtaining an input vector of coefficients originating from the audio signal;
segmenting, in a non-recursive manner, the input vector into an integer number of input vector segments;
determining, in a recursive manner, a representation of a respective relative energy difference between parts of the input vector on each side of each boundary between the input vector segments;
allocating bits for encoding each of the input vector segments and for encoding the representations of the relative energy differences between the input vector segments; and
providing the input vector segments and the representations of the relative energy differences for individual encoding.
