Ear speaker and loud speaker at the same time
I'm making a karaoke app but I have a problem, the the volume of the backtrack that is playing by the loud speaker while I'm singing is too loud and is recorded by the microphone.
With that, when I listen the final result, the sound of the backtrack doesn't sound good...
So the idea is to play the backtrack on the ear speaker AND the loud speaker, like that, I'll can turn down the sound of the loud speaker while maintaining a good general volume with the help of the ear speaker.
In addition, I will play the original backtrack file during the final result to have the cleanest sound possible.
So I'd like to know if it is possible to play a sound by the ear speaker and the loud speaker simultaneously, and if so, how can I do it.
