Audio sources

Products: Video Capture SDK .Net

You can get audio from the following sources:

  • Audio capture devices
  • Audio from speakers
  • IP cameras source
  • NDI source
  • RTSP source

Audio capture devices​

Enumerate audio capture devices.

foreach (var device in VideoCapture1.Audio_CaptureDevices())
{
    // add to some combobox
    cbAudioInputDevice.Items.Add(device.Name);
}

Enumerate audio formats.

// find the device by name
var deviceItem = VideoCapture1.Audio_CaptureDevices().FirstOrDefault(device => device.Name == "Some device name");

// enumerate formats
foreach (var format in deviceItem.Formats)
{
    cbAudioInputFormat.Items.Add(format);
}

Set audio capture device as a source.

// find the device by name
var deviceItem = VideoCapture1.Audio_CaptureDevices().FirstOrDefault(device => device.Name == "Some device name");
VideoCapture1.Audio_CaptureDevice = new AudioCaptureSource(deviceItem.Name);
VideoCapture1.Audio_CaptureDevice.Format = deviceItem.Formats[0].ToString();

Audio from speakers​

Set the audio capture source to VisioForge What You Hear Source to use audio loopback and capture sound from speakers.

VideoCapture1.Audio_CaptureDevice = new AudioCaptureSource("VisioForge What You Hear Source");
VideoCapture1.Audio_CaptureDevice.Format_UseBest = true;

IP camera source​

Use the AudioCapture property of IPCameraSourceSettings to enable audio capture.
