Abstract
Experiments are described in coding broadband audio using multipulse linear predictive coding (LPC). It is possible to obtain stable LPC filters that model sinusoids closely and to include perceptual masking in these coders. The quantization of both the LPC and multipulse parameters is also examined, and it is found that multipulse can compensate for quantization error in LPC filters. With appropriate perceptual masking, these coders can provide high quality and audio output. At 128 kb/s, the coders achieved typical SNR values of 35-40 dB in simulations.Keywords
