Do not forget to change PiAPI node to your way to upload to your bucket, otherwise will not work. Require also FFMPEG NCA Toolkit or other FFMPEG online services to tranform the audio.

Final text extracted: "It's not perfect yet. I'm still refining the Task Manager, but it already gives you a solid springboard to level up your automations. Thanks for watching. I hope this Task Manager setup helps you build more advanced, robust automations in N8n. Good luck, and happy automating."
