Microphone

I think this app is doing what it claims, and it seems to be well-made, and I'm thankful for the lack of ads, but I must reduce my rating due to lack of documentation. I have tried every combination of inputs and outputs, gain, volume, equalizers, etc., and I still cannot figure out what the In and Out settings do. No matter how I change them, they don't seem to control which input the sound comes from or which output it goes to. Also, there is no documentation telling whether the settings you're changing affect the microphone functionality after you exit the app. I learned the hard way that my microphone was still listening and outputting to my BT audio stream after backing out of the app. By messing with all these settings, am I screwing up my microphone for other apps like the Phone permanently?

Maybe this is good.... I guess I'll give one extra star because yes it does exactly what it says it does. But for me, it's not what I'm looking for. Speakers can act as a mic. Physically. So I need an app that will allow me to adjust audio routes. I want to use an external mic for things. And control the levels of that mic. Then also control the audio output routes.

Since I don't know much about audio, maybe a tutorial would be appreciated? After I did eventually find out how everything worked, it works perfectly for helping me record my podcast. There's not too much to fumble with, and it's as simple as turning it on, using it for the app of choice, then turning it off. Satisfyingly simple UI. Much appreciated.
