How to convert a .wav file to a spectrogram in Python3?
Witryna12 maj 2024 · Spectrogram. The frequency spectrum, as the name implies, is the representation method of the “time domain” signal in the “frequency domain”, which is usually converted by the “Fourier transform”. Usually the amplitude is the y-axis and the frequency is the x-axis.
