1. A method of encoding a gain parameter in a generalized linear predictive analysis-by-synthesis coder, comprising:

  • determining a quantized frame gain parameter for each of a plurality of successive subframes of a frame of an encoded audio signal; and

    determining a quantized frame gain parameter for each frame of the encoded audio signal using a delayed decision quantizer operating on the subframe gain parameters.
