Python Audio processing Guide

Introduction

This guide is intended to provide a comprehensive overview of audio processing in Python. It will cover the basics of audio processing, including reading and writing audio files, audio manipulation, and audio analysis.

Reading and Writing Audio Files

I recommend using either pydub AudioSegment or librosa to read and write audio files in Python. Pydub is a simple and easy-to-use library for audio manipulation in Python, while librosa is a more advanced library that provides additional functionality for audio analysis.

from pydub import AudioSegment

Oh my zsh.

Install ZSH.

sudo apt install zsh-autosuggestions zsh-syntax-highlighting zsh

Install Oh my ZSH.
