Abstract :
Adaptive shaping of the quantizing noise spectrum is essential for optimal subjective performance of speech coders. In this paper, we discuss detailed procedures for minimizing the subjective loudness or audibility of quantizing noise in linear predictive coders. The procedure takes account of the frequency analysis by the human ear and its auditory masking properties.
