What is happening for modify_duration? #3
Description
I was trying to modify duration for a sub-duration of a signal, but realized that the synthesizer doesn't generate good quality output. I then noticed this line in the example:
https://github.com/tuanad121/Python-WORLD/blob/master/example/prosody.py#L44
and the modify_duration function, which seems to be exactly what I wanted:
https://github.com/tuanad121/Python-WORLD/blob/master/world/main.py#L177
Seems like the current code fails on this operation? Is there any understand why this is happening?
