LEDs flashing to the sound of music

Hi guys.

Let me start off by saying what I would like to do.

My goal is to get LED strips and put them around the perimeter of my dorm room (its probably around 12x14 feet or somewhere around there), and have these lights flash to the music coming from my computer.

I have been doing my research and looking for some type of module or piece of hardware that I could plug into the wall, plug the lights into, and run a cord from my computer to this device so that it knows when to pulse the lights with the bass of the music.

Unfortunately, I have no experience with any of this yet and would really like some help. I have seen people on the internet with LED organs.... is that the way to go? Or is there a simpler device that would do what I am looking for. I am assuming it will be costly seeing as there will be allooooot of lights going up.

Links to products/ and or explanations as if i was in elementary school would be much appreciated!!! THANKS

 

thanks man!

couple quick questions though.

I didn't see a price on the assembled one.. do you know about how much those run?

also, I am very inexperienced with all of this. how does one change the value of C5 exactly?

and lastly, would you be able to tell me which led strips would be best to line the perimeter of my room with... I figure i need probably somewhere around 50 feet. I don't want to buy crappy cheap lights but I don't to spend an arm and a leg either.

Any good recommendations on which lights would suit my cause the best? (I am assuming, and i might be wrong, but I am assuming the RGB lights are more expensive. If there are just blue led's, that would be more than fine for me, especially if it is cheaper)

THANKS SO MUCH!
