Program for Calculating Statistics of F0
* FOR LITTLE ENDIAN

usage: f0stats [options...] [inputfile] [outputfile]
options:
        -log                            : statistics of log F0
        -all                            : using all values
        -nmsg                           : no message
        -help                           : display this message

The input file is an F0 text file where each F0 is represented by
Hz. The output file is an statistics text file describing mean and
standard deviation. If -log is used, the statistics of log-scaled F0
are calculated.

The statistics are calculated without unvoiced frames represented by
0.0 in the F0 text file. If -all is used, not only voiced but also
unvoiced frames are used for calculating the statistics.

Some messages are printed while executing this program. If you
don't need those messages, use -nmsg.


<EXAMPLE>
% f0map \
	-log \
	-nmsg \
	input.f0 \
	output.f0stat
