For the first exercise of this media 3 class, I was helping my self with zoom H4 to finish the task. the exercise was about an object that I attached to, which was actually my laptop and I replace it with Zoom H4 recorder. besides of using zoom H4 recorder as a replacement device for my laptop, I also use it to record the voice over and the soundtrack for the video. I have used this device in my previous classes, so I already know how to use it.
