Example

This VB example initializes a combo box with the descriptions of available audio recording devices and uses it to select a specific device:

AudioLst = ActiveGige1.GetAudioList

For i = 0 To UBound(AudioLst)

Combo1.AddItem (AudioLst(i))

Next

Combo1.ListIndex = 0

ActiveGige1.SetAudioSource 0

Private Sub Combo1_Click()

ActiveGige1.SetAudioSource Combo1.ListIndex

End Sub

Private Sub Capture_Click

ActiveGige1.StartCapture "c:\\capture_with_sound.avi"

End Sub

Remarks

This method allows you to add the audio track to your AVI file and select a specific audio recording device. If only one recording device (such as a microphone) is present in the system, use 0 as the value of Index. To disable the audio recording, call SetAudioSource with the value of Index -1. Note that by default the audio recording is disabled in ActiveGige.

To initiate the AVI recording, use StartCapture.
