pydub is a Python library for audio processing that enables editing, converting, and manipulating audio files through integration with ffmpeg, supporting formats like MP3 and WAV.
This guide explains how to split a PDF into separate files using PyPDF2 and provides two Python approaches for converting MP3 audio to text—one leveraging Google Speech‑Recognition for higher accuracy and another using PocketSphinx for complete transcription—complete with ready‑to‑run code examples.
This tutorial introduces Python's pydub library for audio manipulation, covering installation, AudioSegment basics, slicing, merging, fading, speed adjustment, playback, gain control, cross‑fade, multichannel creation, and exporting, with a practical example for short‑video post‑production.
