Embedding voice recording in videos

Hi
thank you for creating such an amazing tool. Its great for teaching purposes and the option to copy and paste from the screen is mind-blowing.
I was wondering if there are any plans on adding a voice recording option. in that case it would be a complete tool for teaching anything using the terminal and also step by step note-taking.

It would be nice, yes

Hmmm, this is a cool idea, but it would seem to be tricky to implement.

I was trying some ideas to do this. I want to record an audio from my live coding session with Tidalcycles.
I tried to launch jack_capture and asciinema rec at the same time with some kind of script, but not success yet. I think there is a way to do it. Then you can play both files at the same time with asciinema player and media player on html.
When I have something working, I will share the script here.
