Screen capture app with audio Does the Android OS allow for screen recording with audio? Is there an app that can do this?

I have been using android debug bridge to capture video of the screen, but that comes without audio.

I have tried a couple apps , but have not found any that do audio. I found one that uses the mic to record the speaker, which is obviously pretty crappy.
To create promo videos of my apps, I use ScreenRecorder. It allows you to record with audio and maintains screen orientation of the app being recorded. I don't think your device has to be rooted. It has a high rating and over 10 million downloads.
