In the make_pm_wave script, the default parameters for male and female voices are set like this:

# default male settings 50-180Hz
DEFAULT_PM_ARGS_MALE=’-min 0.0055 -max 0.02 -def 0.01 -wave_end -lx_lf 200 -lx_lo 111 -lx_hf 30 -lx_ho 51 -med_o 0′

# default female settings 100-250Hz
DEFAULT_PM_ARGS_FEMALE=’-min 0.004 -max 0.01 -def 0.01 -wave_end -lx_lf 300 -lx_lo 111 -lx_hf 140 -lx_ho 51 -med_o 0′

I don’t understand why the lx_hf parameter is set to 140Hz for female voices when we are looking to identify a F0 value between 100 and 250Hz. If we apply this 140-300Hz filter, how can we find F0 values between 100 and 140Hz? This confuses me more since the lx_hf parameter for males is set to 30Hz, i.e. 20Hz below the threshold of 50Hz.
