Hello @aizquier ,

This is a bit of an unrelated question but I was wondering if you had any idea on how one could encode (digitally) their own personal images into audio with the same specifications as the images you decoded from the Voyager audios?

I really appreciate the aesthetic look of the decoded images and would like to see if I could have the same effect with my own personal photos. Would greatly appreciate your perspective.

Thank you!
