Split gain shape vector coding

A media encoder configured to:

• determine an initial number (Np_init) of segments for a target vector x;
• determine energy of each Np_init target vector segment;
• determine an average number of bits per segment (BAVG) based on a vector bit budget and Np_init;
• determine a final number of segments by increasing the initial number Np_init of segments if a relation between the energies of the Np_init segments and the difference between a maximum number of bits for a vector segment (BMAX) and BAVG meets a determined condition;
• and
• indicate the increase of the number of segments to a media decoder.

A media decoder configured to:

• determine an initial number of segments, Np_init, for a vector xq to be reconstructed;
• receive an indication of whether an increased number of segments is applied for the vector xq, or not, and
• determine a final number of segments, Np, for the decoding of the vector xq based on the received indication, wherein
• the media decoder is configured to determine whether the received indication indicates that an increased number of segments is applied for the vector xq, and
• the media decoder is configured such that, as a result of determining that received indication indicates that an increased number of segments is applied for the vector xq, the media decoder determines the final number of segments, Np, to be equal to (Np_init+X), wherein X is greater than or equal to one.
