If you mean you want to create a .NET C# application to process Audio steams (audio signals), you can try using LEADTOOLS DirectShow Audio Processing filters, such as Detection, Chorus, VU Meter, etc. You can find more details here: https://www.leadtools.com/help/leadtools/v19/multimedia/filters/filterscodecsandinterfaces-audiofilters--rollup.html Note that you can use these filter in conjunction with LEAD player, convert or capture controls. For example, the following code shows how you can use the LEAD Audio Volume Transform filter with the Player control: ////////////////////////////////// public PlayCtrl _playctrl = null ; public void GetSubObjectExample() { // input and output file names string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_Source.avi" ); try { // reference the convert control _playctrl = _form.PlayCtrl; // get index of LEAD MF Volume Transform int nIndex = _playctrl.AudioProcessors.IndexOf( "{E2B7DC41-38C5-11D5-91F6-00104BDB8FF9}" ); // add the LEAD MF Volume Transform to the selected audio processors _playctrl.SelectedAudioProcessors.Add(_playctrl.AudioProcessors[nIndex]); // //LMFAVolume lmfVolumePro = _playctrl.GetSubObject(PlayObject.SelAudioProcessor) as LMFAVolume; //if (lmfVolumePro != null) //{ // change some settings // lmfVolumePro.Mute = true; // Marshal.ReleaseComObject(lmfVolumePro); // } --> // set the source file _playctrl.SourceFile = inFile; } catch (Exception) { _result = false ; } // 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 (_playctrl.State == PlayState.Running) Application.DoEvents(); _result = true ; } //////////////////////////////////
