##Pitch corrector Voice Effect

This pitch corrector algorithm is organised in three python files:

• main.py : the main file that implement the pipelining of the different methods
• methods.py : contains the methods that are called from main.py
• settings.py : the settings that you can play with to adjust the voice effect

##Use

To launch the program, simply use the following command:

python main.py

Advice for the settings:

If using mic as input_type, put headphones, there is no larsen protection The parameters to change for FFT_size is the power of 2. Change the value x in "FFT_SIZE = 2**x * window_size"

Precisions in the comments of settings.py
