/* Constructor
Input arguments:
t_nLPC: LPC order
t_sr: sampling rate of the input signal (Hz)
t_bufferSize: input buffer size (# of samples)
t_nFFT: FFT length (must be power of 2)
t_cepsWinWidth: cepstral liftering window width (dimensionless)
t_nTracks: Number of formants to be tracked
t_aFact: alpha parameter in the DP formant tracking algorithm (Xia and Espy-Wilson, 2000)
t_bFact: beta
t_gFact: gamma
t_fn1: prior value of F1 (Hz)
t_fn2: prior value of F2 (Hz)
If cepsWinWidth is <= 0, cepstral liftering will be disabled.
