I can't believe this app doesn't already exist. What I need is an app that will allow me to control the output volume of the phone's built in mic and the earbud mic. Sounds pretty simple doesn't it? Guess what? IT DOESN'T EXIST!!! I'm very much into audio and video production, being an ex radio guy. So I know my way around pro gear like compressors, limiters, noise gates, etc, etc. Having used my voice in a professional capacity for so long (even now when I do voice overs from my home studio), I don't want to have to raise my ALL the time..."Ca n you hear me now?!?!". You get the idea. I tend to be quite soft spoken on the phone, kinda laid back. Can someone PLEASE come up with a simple mic output volume control?
