PodcastGen is a Python-based command-line application that automates the entire podcast production workflow. Users supply Markdown or plain text scripts, and PodcastGen parses headings into chapters, generates AI-narrated audio with customizable voices and pace, mixes in background music tracks, and even outputs an RSS feed for immediate distribution. Its modular design allows advanced configuration of TTS engines, music libraries, and output formats, enabling creators to produce high-quality podcasts in minutes rather than hours.
