This Python video tutorial show how to read and visualize Audio files (in this example - wav format files) by Python. For this reason librosa module is using.
In addition to that matplotlib library is a perfect tool to visualize amplitudes of audio files. Glob module is used for reading audio files from working directory.
Matplotlib - matplotlib.org/
Glob module - docs.python.or...
More reading about librosa in official documentation: pypi.org/proje...
In simple words - LibROSA is a python package for music and audio analysis. It provides the building blocks necessary to create music information retrieval systems.
Dataset source: www.kaggle.com...
I will try to develop this topic (audio files analysis) in the context of Machine Learning. For example classification task to identify the male or female voice is on the audio.
Best regards.
Vytautas.

I have created another one video demonstrating simple use of glob module: just how to read external files (2 simple methods) some time ago: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1nc5Sju8FVU.html
