I am developing a web application in that I need to record audio, for that I am importing "winmm.dll" and
using mciExecute function.(the following code is vb.net). If I have posted in irrelavent forum please let me
know where should I post questions related to audio and video (for web development).
-
Imports System.Runtime.InteropServices
-
Imports Microsoft.VisualBasic
-
Imports Microsoft.VisualBasic.Devices
-
-
Partial Class audioRec
-
Inherits System.Web.UI.Page
-
<DllImport("winmm.dll", EntryPoint:="mciExecute", CharSet:=CharSet.Ansi, SetLastError:=True,

-
ExactSpelling:=True)> Private Shared Function mciExecute(ByVal lpstrCommand As String) As Boolean
-
End Function
-
-
Protected Sub BtnStart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnStart.Click

mciExecute("open new Type waveaudio Alias recsound1")

mciExecute("set recsound1 time format ms bitspersample 16 channels 1 samplespersec 11025")

mciExecute("record recsound1")

End Sub
