please help. I need a flashing background with sound

[beibitoi]

Hi please help me make a very simple page that only have a blinking background like this:

http://www.bluestwave.com/tools/dreammachine.html

however, I also need that blinking light to sync with a sound like this.



i.e., for every flash of light, there should also be a single pulse of a sine-wave tone.

That's all I need. I'm trying to make an audio-visual stimulator. to give you an idea, it looks like this

Amazon.com: PSIO 1.1 Audio and Visual Mind Stimulator: Health & Personal Care

I figured out I can use my laptop monitor as my goggles.

If I can just get that light to come up with a sine wave tone, I wouldn't need to spend hundreds of dollars to get what I need. I'll just simply bring my laptop monitor closer to my eyes and wear my headphones. I have here on my laptop the files for the sine-wave tone which I made with audacity.

I'm thinking of getting the source code from the flashing light site and maybe do a little tweaking for the sound, and then saving it as html.

I don't know if I have stated clearly what I intend to make but I can provide more information if needed.

Thanks in advance for the help. I'm too desperate to have an audio-visual stimulator but I don't have enough funds to acquire one. Again, thank you!
