Example
C#
using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void CaptureAudioExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   // output file for capture 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "CaptureCtrl_CaptureAudioExample.mp3"); 
 
   try 
   { 
      // select a audio capture device 
      if (capturectrl.AudioDevices["USB"] == null) 
         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true; 
 
      // set the audio compressor 
      capturectrl.AudioCompressors.AC3.Selected = true; 
 
      // set the target output file and format 
      capturectrl.TargetFile = outFile; 
      capturectrl.TargetFormat = TargetFormatType.MP3; 
 
      // unmute the audio, balanced and full volume 
      capturectrl.Mute = false; 
      capturectrl.Balance = 0; 
      capturectrl.Volume = 0; 
 
      // check whether we can capture audio 
      if (capturectrl.IsModeAvailable(CaptureMode.Audio)) 
      { 
         capturectrl.TimeLimit = 5;      // just 5 seconds of capture time 
         capturectrl.UseTimeLimit = true; 
 
         // start the capture process 
         capturectrl.StartCapture(CaptureMode.Audio); 
 
         // we'll loop on the state and pump messages for this example. 
         // but you should not need to if running from a Windows Forms application. 
         while (capturectrl.State == CaptureState.Running) 
            Application.DoEvents(); 
 
         // set the result 
         _result = File.Exists(outFile); 
      } 
   } 
   catch (Exception) 
   { 
      _result = false;
