How To Plot An Audio Signal In Python Using Matplotlib | Tutorial For Beginners

Plot any audio signal using Python!

Code snippet to plot an audio signal in Python

Explanation:

1. Function plot_signal() plots the given signal using the passed-in time base (if given).
2. Function plot_signal_and_save() calls plot_signal() and then saves the figure to the disk while making sure that the output_path exists. You can show the figure with plt.show() but when you use it, you won’t be able to save the figure as a file.
3. The main() function generates an example waveform (with time), plots it and saves to the disk using plot_signal_and_save().
