Many people are asking for this, no one seems to have an answer so I do neither.
How is it possible that some apps serve the function to record the audio output of the android system? Everything I am finding is the very same tutorial on 1432 different sites where you can record MIC input. I don't care about mic input, I want the audio output and just can't imagine how to access it.
If everyone can get me on the right way, I would be so happy.
Seems to be currently there is no way to achieve this.
