How to capture audio from the output device (speakers) in Video Capture SDK .Net?
Sample code
1. Set audio capture source to “VisioForge What You Hear Source” to use audio loopback and capture sound from speakers.
VideoCapture1.Audio_CaptureDevice = "VisioForge What You Hear Source";
VideoCapture1.Audio_CaptureDevice_Format_UseBest = true;
2. Set audio capture mode
VideoCapture1.Audio_RecordAudio = true;
VideoCapture1.Audio_PlayAudio = true;
VideoCapture1.Mode = VFVideoCaptureMode.AudioCapture;
3. Set audio output to MP3 (with default parameters)
VideoCapture1.Output_Format = new VFMP3Output();
VideoCapture1.Output_Filename = "output.mp3";
4. Start capture (sync or async)
await VideoCapture1.StartAsync();
