Whats it called? I'm having a block

So I've seen this before but i can't remember what it is called right now.
I want to play music and then have some LEDS make those cool bar visualization things but i'm having trouble remembering what components i'll need to make that happen.
Anybody wanna help out?

You mean Spectrum Analizer, VU meter sometimes called a Graphic equalizer (although not the best term)??

look at the LM3914 datasheet

A graphic equaliser is a set of pots, not a set of lights.

Yes I know, but for but do a google image search and you will see! I think its a hang over from Hi-Fi advertising garbage

You should check out the MSGEQ7 chip too. Sparkfun sell it and it basically does all the hard work.

One of those, seven LM3914s and a bunch of LEDs and you'll be on your way.
