Detecting when two different audio sources are emitting sound in Unity

Dear all,

Dealing with multiple audio sources has not been quite as straightforward as I would've hoped in Unity. While I have been able to play multiple audio sources with no problem at all, I want to gather better information on the audio sources.

I.e: say I have two audio sources, both 10 second clips. Audio source A makes sound from second 1 to 5 and Audio source B makes sound from 3 to 10. I would like to know the percentage amount of time both sources emitted sound and during what times where Audio source A and B overlapping each other.

I have tried utilizing an Audio Visualizer, but I haven't even been able to visualize two different sources without the visualizer's affecting each other.

Any help would be greatly appreciated.
