Remote control to start recording audio in computer

[J_Nichols]

I'm building a circuit where one person speaks and the computer records the voice.
I've the wireless microphone and a receiver. The idea is to record audio while the user is pressing a button. When the button is released, the recording stops.
I want to add the functionality to the microphone.
What kind of circuit can you suggest to perform that task?

Rather than adding complexity to an existing device, have you considered using recording software which is triggered by the audio signal which it is to record?

I can suggest VoxRecorder https://antoninoporcino.xoom.it/VoxRecorder/

also Scanner recorder https://www.softpedia.com/get/Multimedia/Audio/Other-AUDIO-Tools/Scanner-Recorder-Scanrec.shtml

When I did some playing with these a few months ago, I preferred VoxRecorder. Your mileage may vary.

So you mean to activate the recording only when a specific signal is present. That is the way I thought also. But the question is how to trigger that signal in the program. The computer is hearing to the remote mic, but the device has to produce a tone/signal to trigger the recording event. Some modifications need to be done to the audio transmitter, to send that signal.
If not, correct me.

Or maybe introducing to the circuit some modification to produce a specific tone when a button is pressed? I mean to add an extra audio signal (the tone) to the microphone.
