In this new normal, most people shift to online content like seminars, meetings and specially churches.
Here is my current project designed to give you better audio for online streaming. It is basically a link to your analog mixer to your computer. It is also known as USB audio interface. What made it different to other products in the market is the integration of sliding fader for better volume control. For church online streaming, you have big volume difference between the band performing and the pastor preaching, the sliding fader makes it easy for such volume adjustments.
