I'm working on a soundboard software (using VB-Audio Virtual Cable)

I need to pipe the input coming from a specific audio input device (not default) to a specific output device with CMD or PowerShell (so it can be done programmatically)

I've tried using ffmpeg and ffplay, but I couldn't get them working

Edit

I've managed to achieve the desired behavior just from Windows setting

enter image description here

Now I just want a way to do it programmatically (automatically)

  • Post an FFmpeg command that records your "microphone" device into an audio file. Post FFplay command that plays an audio file to your audio output device. Configuring a pipe may be simple.

  • I figured the ffmpeg part, but I couldn't find how to select the output device with ffplay

  • I also couldn't find it. I think we can't select the output device with FFplay.

  • @Rotern, have you managed to do it with some other tool?

  • No, but the following post shows how to change the default audio device using command line.
