I have a circuit in which a simple microphone is used. The circuit is connected to PC with the USB interface as an input audio device (microphone).
Now instead of using a real microphone in this circuit, I need to replace the microphone with a simple circuit to simulate a fixed signal. In fact I want to see a fixed signal level in my software in the computer without any other change to my circuit. I only want to replace the microphone with an equivalent circuit that generates a fixed signal.
Please suggest me some as simple as possible circuits to replace with microphone.
