Python and MatLab code for Fourier transform book at https://jim-stone.staff.shef.ac.uk/Fourier

PYTHON
fourierdemo.py
Simple Fourier transform of two signals: synthetic and voice.
The voice signal is read in from the file: sebinpubaudiIMG_1563.wav.
Instructions.

  1. Download file fourierdemo.py.
  2. Downlod file sebinpubaudiIMG_1563.wav.
  3. Set variable called testing to 1, and run code.

MATLAB
fourierdemo.m
