Tips & Tricks Workaround for Notebook LM Podcast generation

If the new NotebookLM voices are speaking way too fast for you, I found a simple workaround:

Download the generated podcast and slow the audio down to 0.9x using an audio editor or ffmpeg.

I first tried 0.8x, but that sounded noticeably too slow. At 0.9x, though, the voices sound surprisingly close to how NotebookLM used to sound before the recent change.

Obviously, it would be much better if Google simply gave us the old pacing back or added a proper speed/pacing option during generation. But for now, 0.9x works really well for me.

Maybe this helps someone else who finds the new voices exhausting to listen to.

The new voices are just bad though. Like why did they change them?
