1. A method for decompressing a bit stream including signal vector quantization indices and residue vector quantization indices, including: decoding an output bit stream into vector quantization indices and residue vector quantization indices; applying an inverse vector quantization algorithm to the vector quantization indices to generate signal coefficients; applying an inverse transform to the signal coefficients to generate a time-domain reconstructed signal waveform; applying a stochastic noise synthesis algorithm to the residue vector quantization indices to generate a time-domain reconstructed residue waveform; combining the reconstructed signal waveform and the reconstructed residue waveform as a reconstructed input signal waveform block; and applying a boundary synthesis algorithm to the reconstructed input signal waveform block to generate an output signal having substantially reduced boundary discontinuities.
