[hts-users:02622] Why is there no LSP postfilter in HTS demo?

[那兴宇 <nxy-yzqs@xxxxxxx>]

Hi,

I found that their is a postfilter of MGC in both HTS demo and HTS_engine.
But why the LSP postfilter not applied to do some formant enhancement work? Like the one in ITU-T G.723.1.
It involes a FIR filter, a IIR filter and a pre-emphasis filter, seems realizable using SPTK.
