Audio buffers

[MHD A. Ayyash]

How can I write directly to audio device output buffer, or the speaker of it, and how can read the microphone input directly from it's buffer, is there any API function to do that?

To read from a microphone, you could use the mciSendString API.

Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As Any, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As Long
                                       
Private Sub cmdRecord_Click()
 
    'Open a WaveAudio called Record
    mciSendString "open new type waveaudio Alias record", 0&, 0, 0
    'Start Recording
    mciSendString "record record", 0&, 0, 0
    
End Sub
 
Private Sub cmdSave_Click()
 
    'Stops recording
    mciSendString "stop record", 0&, 0, 0
    'Saves the sound
    mciSendString "save record C:\Windows\Desktop\MyWav.wav", 0&, 0, 0
    'Close "Record"
    mciSendString "close record", 0&, 0, 0
                                       
End Sub
