Hi experts, tt seem that here i can get your help.

I have:
Real audio playback device (RPD) . Real audio recording device
(RARD) and a Virtual audio device (VAD).

To test how to record sound on playback device , i try to do as follow :
1. Open GraphEdit (directX 2003).
2. Insert RAPD , VAD and RARD and make a connect between these filter .
3. Play an audio file in windows media player 9.

So, Sound will be followed same as below:

Sound is playing ---> RAPD ---> VAD ---> RARD ---> record sound is
playing by "SoundRecorder" tool.

I wonder these steps right? If i open Sound Recorder tool on windows and
press on Record button , can i capture sound is playing?
If not, can you show me how to connect (what filters to insert and order of
inserting) between these
filters so that i can record sound are playing on RAPD .

This is important to me, so thank so much for any your help.

Virtual Audio Device is an audio source, correct?

Then you can only create the graphs like VAD -> (compressor?) -> file,
VAD -> (compressor?) -> RARD and nothing else.

Hi Maxim S. Shatskih, thank for your answer.

The VAD is available after i build MSVAD and i get this from
...\WINDDK\3790.1830\src\wdm\audio\msvad\multstr . It is said that this will
"Implements multiple playback streams" in readme.htm file.

I will try to do as your suggestion but i wonder this vad can be used for
recording sound ? If not , can show me what type of vad can be used ?

Many thank to you.

If i get multstr (available in MSVAS after building) as VAD then this can be
"an audio source" ?
