Spectrum Representations. ¶. The plots show different spectrum representations of a sine signal with additive noise. A (frequency) spectrum of a discrete-time signal is calculated by utilizing the fast Fourier transform (FFT). import matplotlib.pyplot as plt import numpy as np np.random.seed(0) dt = 0.01 # sampling interval Fs = 1 / dt ...

The FFT is such a powerful tool because it allows the user to take an unknown signal a domain and analyze it in the frequency domain to gain information about the system. In the next entry of the Audio Processing in Python series, I will discuss analysis of audio data using the Python FFT function.
