Fourier transformation with audio input in python
https://stackoverflow.com/questions/52293537/fourier-transformation-with-audio-input-in-python
So I found the Fourier transformation and now I'm trying to transform my audio file with Fourier and plot it. My questions are: How can I plot a Fourier transformation with audio input in python? And if that is working, how can I input the Fourier transformation in the neural network (I thought perhaps give every neuron a y value with the ...

https://realpython.com/python-scipy-fft/
The Fourier transform is a powerful tool for analyzing signals and is used in everything from audio processing to image compression. SciPy provides a mature implementation in its scipy.fft module, and in this tutorial, you’ll learn how to use it.. The scipy.fft module may look intimidating at first since there are many functions, often with similar names, and the documentation uses a …

Short Time Fourier Transform using Python and Numpy. The Short Time Fourier Transform (STFT) is a special flavor of a Fourier transform where you can see how your frequencies in your signal change through time. It works by slicing up your signal into many small segments and taking the fourier transform of each of these.
Fast Fourier Transform (FFT) — Python Numerical Methods
https://pythonnumericalmethods.berkeley.edu/notebooks/chapter24.03-Fast-Fourier-Transform.html
Fast Fourier Transform (FFT) The Fast Fourier Transform (FFT) is an efficient algorithm to calculate the DFT of a sequence. It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished work in 1805. It is a divide and conquer algorithm that recursively breaks the DFT into ...
