I'm working on a sound recorder in Visual Studio 2008, and I currently have it up to the point where I can record from the Media Control Interface using the mcisendstring command. Very similar to a program seen here:
Public Class Form1
Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Button1.Enabled = False
Button2.Enabled = True
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
Label1.Text = "Recording..."
Label1.Visible = True
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Button1.Enabled = True
Button2.Enabled = False
Button3.Enabled = True
mciSendString("save recsound c:\recsound.wav", "", 0, 0)
mciSendString("close recsound", "", 0, 0)
MsgBox("File Created: C:\recsound.wav")
Label1.Text = "Stopped..."
Label1.Visible = False
My.Computer.Audio.Stop()
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Label1.Text = "Playing..."
Label1.Visible = True
My.Computer.Audio.Play("c:\recsound.wav", AudioPlayMode.Background)
End Sub
End Class
This method records using the current input of the Windows MCI; however, what I'm trying to accomplish next is the ability to record multiple channels simultaneously using many different inputs. Does anybody know if this is possible using mciSendString, or should I go a different route? (Or even with a different programming language entirely?) I'm open to any ideas; I know very little about audio, but I know plenty about programming. Thank you for your help.
