Subband coding with modified multipulse LPC for high quality audio

A modified multipulse excitation linear predictive coding (MMPLPC) structure combined with a subband (SB) technique is proposed to encode audio signals of 15-kHz bandwidth. The bit allocation is dynamically adapted according to both the signal power in different subbands and a perceptual hearing model. Informal listening tests showed that high fidelity audio coding can be achieved at bit rates of less than 86 kbit/s by SB-MMPLPC.<<ETX>>
