Description:
Builds a spectral envelope from a list of formants.
The spectral envelope is returned as a BPF object.
Formant values must be formatted as '((frequency1 amplitude1 bandwidth1) (frequency2 amplitude2 bandwidth2) ...)
Amplitudes are expected in dB.
<res> is the number of points in the envelope.
<maxf> is the value in Hz of the maximum frequency in the envelope.
If <db> is selected (T) amplitudes are returned in dB, else they are returned as linear values.
This function is inspired from initial works by Ph. Depalle and X. Rodet.
