#60 -o option in mgc2sp

[Keiichi Tokuda]

-o option is inconsistent between mgc2sp and mcep, mgcep, etc.

mgc2sp - transform mel-generalized cepstrum to spectrum

usage:
mgc2sp [ options ] [ infile ] > stdout
options:
-a a : alpha [0]
-g g : gamma [0]
-c c : gamma = -1 / (int) c
-m m : order of mel-generalized cepstrum [25]
-n : regard input as normalized cepstrum [FALSE]
-u : regard input as multiplied by gamma [FALSE]
-l l : FFT length [256]
-p : output phase [FALSE]
-o o : output format [0]
0 (20*log|H(z)|)
1 (ln|H(z)|)
2 (|H(z)|)
3 (|H(z)|^2)
-p option is specified
0 (arg|H(z)|/pi [pi rad])
1 (arg|H(z)| [rad])
2 (arg|H(z)|*180/pi [deg])
-h : print this message
infile:
mel-generalized cepstrum (float) [stdin]
stdout:
spectrum (float)
notice:
value of c must be c>=1
