What happens if I open an audio file MP4 in a text (word processing) app?

Imagine you have a book that’s written in Korean. If you gave it to me and asked me to read it out loud, I wouldn’t be able to make sense out of it. If you gave it to a Korean person, however, they could read it perfectly fine.

The book itself hasn’t changed — just the person reading the book. And that person has a different set of skills (or instructions, if you will).
