formant frequency bandwidth of LPC root
For formant estimation from LP polynomial roots, more roots amplitude shows that poles is near to unit circle in Z-domain but
Can anyone explain why the bandwidth of the formats must be small ?
I have ...

Format location from LPC magnitude
I am confusing when I find the lpc roots magnitude, f1=0.9313, f2=0.9308, f3=0.91 and f4=0.95 but when I look at LPC envelope the f1 is higher than f4 in term of magnitude in dB.
Could anybody explain ...

Matching an LPC Magnitude Spectrum to FFT Magnitude Spectrum
I'm trying to get an LPC magnitude spectrum to match to an FFT magnitude spectrum. Basically I want the peak height in the LPC Spectrum to match the peak height in the FFT Spectrum.
Thanks to ...
