Let's say I'm listening to text to speech audio from an Android app. I want to have some low volume instrumental music playing at the same time in another app. (Both apps allow simultaneous playback.)
The problem is that the music is too loud, and makes it difficult to hear what is being spoken by the text to speech. If I try to turn the volume of my current music player down, the whole Android system audio will be turned down, including the text to speech. Obviously, this defeats the purpose.
Therefore, I'm looking for a music player for Android which has its own volume control, one which will not affect the main Android volume.
