    The same friend I'm building a computer for had this idea that you could configure a bunch of LED lights to blink to the beat of his music. I told him it's very unlikely you'll find any software for this and neither of us would have any chance at screwing around with a bunch of LED's and getting to to work like that but it's his computer. So do any of you know of any way to do this? Hardware or software methods of course. Thanks.

    can you not programme a PIC chip to do it?? We scraped the surface of PIC chips in electronics and we had LEDs that went on and off in time with the song.

    You could get a cold cathode tube (which is basically just a big LED). They make some which are sound responsive, and you can change the sensitivity with a built-in potentiometer.

    Wow sounds pretty sweet. Build in potentiometer? Is that included with the light you say? Do you know where I could get any?
    Sorry Nic what are PIC chips?
    Thank you both though, I never thought it would be that easy:)

    Winamp has a beat thing when you play music. The PIC will only work with digital signals, not analog frequencies.

    Okay, so get Winamp and some sound sensitive cathode tubes, cool. Thanks.

    I always recommend Newegg for such things, but I digress. :)

    I myself have a Sunbeam 12" blue cathode and can only recommend it!
    It's a fantastic tube and is highly responsive, lights up the whole room!

    i've got some cold cathode tubes on order with my PSU and AeroCool GateWatch LCD fan thingy....i dont think they're sound response though, oh well i'll try and find a kit that is (and has 2 cathode tubes) so i can have 4 cathode tubes!

    you could connect some 5v christmas lights to your usb, add a transistor on the green (data) wire and write a program to make them blink to pulses :)

    Thanks guys, wow I just assumed Newegg didn't carry sound responsive cold cathodes but guess I was wrong. So you think voice activated once would keep up with the beat? Good idea ninja, that's what I had in mind first except I wouldn't know where to start with the program:(

    Most of them keep up pretty well!
    Sunbeam and Flexiglow are the only id recommend!

    Yes, they 'keep up' very well, assuming you have the sensitivity level set properly for the sound amplitude. It's a nice affect, but the novelty quickly wears off. Good thing the good ones come with an on/off switch! BTW, Vantec and Thermaltake are both good choices.
