I found out how to create a regular stereo mixer to combine multiple inputs to one output.
I like this but want to go one step further.
I wish to only have two inputs. One input is always live, while the second one is open.
When the second input starts to output a signal, the first input opens allowing the second one to close.
I first thought, hey a relay would work great. But then realized that audio is an AC current, and not DC, nor is it high enough to trip any relays I have found. What I next thought was to use a power source and capacitor to charge up the relay to a certain voltage, then when the audio line because active, it would put it over the necessary value. However, that would be very hard to regulate.
I then thought of transistors, but I'm not to familiar with them in being used as a switch, and from what I read, it probably won't work.
I would really love to get this working in a simple plug and play method. I don't have time to write some code and create an piece of hardware paired with software to monitor the second input's voltage.
Simply put, if the second input's voltage goes higher then 0, then open the first input and close the second one until the second one's voltage goes <= 0 and then close input one and stay like that until the condition is met again.
Thanks all!
