Voice recording on ASP.NET RRS feed

  • Question

  • I am using winmm.dll to record audio from user and save it in to directory. Every thing was work fine but after publishing using URL it says, the audio file was not found. Path is correct but the audio is not saving.

    [DllImport("winmm.dll", EntryPoint = "mciSendStringA", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
            private static extern int record(string lpstrCommand, string lpstrReturnString, int uReturnLength, int hwndCallback);

    protected void btnStopRecording_Click(object sender, EventArgs e)
            {
                try
                {
                    lblRecording.Visible = false;
                    string userId = Request.QueryString["id"];
                    timer.Enabled = false;
                    string path = Server.MapPath(@"~/Recordings/'" + userId + "'(1).wav");
                    path = path.First().ToString().ToLower() + path.Substring(1);
                    record("save recsound " + path, "", 0, 0); 
                    record("close recsound", "", 0, 0);
                    btnStartRec.Enabled = false;
                    btnStopRecording.Enabled = false;
                    btnSave.Enabled = true;
                }
                catch (Exception)
                {

                    throw;
                }
            }

     Can anyone help me with the issue.

  • Since the recoding is done on ASP server, but the form is displayed in browser on different computers, it is not clear how it will record the sounds.
