Show HN: Operation Voidstar, AI-Generated Conspiracy Comedy

This is an AI side project I've been having a lot of fun with. I start with an absurd premise, then generate "source documents" with ChatGPT. Then I feed those into NotebookLM and generate a podcast. The theme is from Suno. I use ffmpeg and sox to composite and edit audio. I'm actively looking for alternatives to NotebookLM for the audio synthesis, if anyone knows any.
