And another one, hahaha!
And to have asked that: This only works with existing Video Files, doesn't it? You can't take a Link to a YouTube Video and it will grab it and transform; is that correct? Isn't a Critique, only for Clarification.

I have tested it now and it worked fine. No Errors or Audio Issues so far. But I would mention 2 Things:
- Maybe You could add the Functionality to Your Dual-Panel Extension.
- The File now lands automatically in the Folder where the Video File is. Maybe You could add the File Save Window where You can choose where the File will be saved.
New version of Dual Panel and Video to Audio
- I found a trick to watch if the extension is charged when you launch Dual Panel and add a right click to launch it. It was more easy than I thought and nautilus doesn't push the CPU

- the easiest and it's done
You can download the 2 new extensions

I downloaded both and they work fine for me. Audio Extraction in Dual Panel and the File Saving Function worked well without an Issue or Error.
