New Post: AudioFileReader copyto progress

How would I be able to update a progress bar if I am copying a wav file to a mp3 file

I use the following code to copy the file and it works perfectly I just want to be able to show the progress of the copy to the enduser

        using (reader = new AudioFileReader(FilenameTextBox.Text))
        {
            reader.Volume = VolumeTrackBar.Value * 0.5f;
            using (LameMP3FileWriter writer = new LameMP3FileWriter(string.Format(@"{0}\{1}.mp3", DestDirTextBox.Text, SermonTextBox.Text), reader.WaveFormat, 128))
            {
                reader.CopyTo(writer);
            }
        }
