Voice Frequency Extraction Signal Processing (numpy)

### this script is provided with my paper of research and an audio file for example purposes only.

This script is reading an audio file and extract frequency of the voice detected in the audio file using numpy library and Discrete Fourier Transform algorithm (FFT).

Note: the script is developed in exception handling that might occur when the audio file is corrupted or did not detect a valid voice to apply the FFT algorithm on it (in case you tried another audio file and did not work out try to make one more or change your input audio device).

This script is a follow of the previous script of (audio splitter that can extract voice frequency from several files at once).
