Why is there no app for internal sound recording?

[AC Question]

I've done some research and realized that there is no app that can record just the system sound!

Why is that? Why has nobody made such an app so far? Is it possible to make that app?

Welcome to the forums. I'm afraid you lost me at internal sound recording. Can you elaborate, please?

Because there's no API you can call to get the internal sound. Android just isn't written to allow that. (Which is why most phones can't record both sides of a phone conversation either.)
