Can anyone tell me whatz the use of "PERCEPTUAL WEIGHTING FILTER" ?
why its so necessary in speech coding?
thanx in advance.

The Harmonic noise shaping filter and the formant perceptual weighting
filter are both based on the same principle - they try to minimise the noise

Hi Kevin Jiang,
Post filtering is done to improve the perceptual quality of speech. Most of the
algorithms focus on emphasising the formants and pitch harmonics whi...
