Downloading an audio file from a streaming server

Question

Hi I am unable to download an audio file from a streaming server. The audio is downloading but only 388 bytes is showing.Can you help to resolve the problem. Thanks in advance.

My code is as follows:

    string strExt, audiofile, mpg;
    strExt = rdoformats.SelectedValue.ToString();
    audiofile = Session["audio_name"].ToString();

    int j = audiofile.LastIndexOf(".");
    mpg = audiofile.Remove(j);
    mpg = mpg + strExt;
    string url = string.Empty;
    if (url == null || url.Length == 0)
    {            
        url = "http://path/oflaDemo/";
    }

    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
    int bufferSize = 1;

    Response.Clear();
    Response.AppendHeader("Content-Disposition:", "attachment; filename=" + mpg);
    Response.AppendHeader("Content-Length", resp.ContentLength.ToString());
    Response.ContentType = "application/download";

    byte[] ByteBuffer = new byte[bufferSize + 1];
    MemoryStream ms = new MemoryStream(ByteBuffer, true);
   // Stream rs = req.GetResponse().GetResponseStream();
    Stream rs = resp.GetResponseStream();
    byte[] bytes = new byte[bufferSize + 1];
    while (rs.Read(ByteBuffer, 0, ByteBuffer.Length) > 0)
    {
        Response.BinaryWrite(ms.ToArray());
        Response.Flush();
    }
        Response.End();
        ms.Close();
        ms.Dispose();
        rs.Dispose();
        ByteBuffer = null;
