  • Methods for selecting an initial quantization step size in audio encoders and systems using the same
    Patent number: 7668715
    Abstract: A method of performing quantization in an audio encoder includes determining a number of bits available in a frame of encoded audio data. Determinations are also made for the maximum transform coefficient value and a distribution of transform coefficient values across the transform coefficient spectrum being encoded. A an estimate for an initial quantization step value is determined from the number of available bits in the frame, the maximum transform coefficient value, and the distribution of coefficient values across the coefficient spectrum.
