Those TAOS sensors look promising, I checked mouser and there are a lot to choose from and they are cheaper than I thought they would be.

I was hoping to leave a computer out of the equation so hopefully I can get something working with just the arduino.

If anyone has suggestions on some multi color led lights to use that would be helpful too.  I was hoping to buy some of the GE g-35 christmas lights but can't find them anymore, the only other serial communication ready lights I found were $5 a piece.

I want to use something to sense what the majority of the color on at tv screen is and have ambient lighting throughout the room reproduce that color.  I'm new to arduino but it doesn't seem like video processing is an option.  What kind of sensor that arduino could support would work best?

do you know if i could do the same thing --> control led lights using a playlist of say 3 songs in max/msp and then sending it to arduino to change the led colors?
I'm not familiar with max/msp, I just got Arduino 2 weeks ago.  Any analog signal will work with this program regardless of the source.  To get bass isolated you would still need to create a filter before the signal is put into the Arduino since the code only performs actions based on amplitude and doesn't do any filtering.  I looked up max/msp and plan to mess with it in the near future so if you still have trouble I may be of more assistance later.

Unfortunately not actually beat detection, I was kinda hoping for some true 'beat detection' code which is extremely difficult.
Yes, but I couldn't think of any good reason to actually detect the beat pattern of music, if you want to play different songs or very dynamic music a program that detected beats would not be very useful.  This program allows for rapid change in music intensity and rhythm and will still perform actions based on the bass hits as long as you have a halfway decent filter. 

I can add a few lines of code to estimate BPM if you were looking for something like that.  If you have an awesome project idea that requires being able to estimate the upcoming beats in music before they are played then you can let me know and maybe it will inspire me to take up the coding challenge, for the projects I have in mind though this is all I need.

Hey Alcafuz,

I just finished writing code for using an electret with an Arduino.  I posted my code in the topic about music detection.  I use a 386 to amplify the signal first and it is just enough, more amplification would be better but would also be more expensive, so I made the code do the work.  Let me know if you have any questions about it.  Also when I was looking up specs on electret microphones most suggested low voltages around 2V so I used the 3.3V power with a resistor to power it, I don't know what my specific model mine is, it just came with a box of random electronics, but it seems to work well.

I plan to make a product using this code soon and decided to take it down, sorry.  I hope everyone who got a chance to try out the code enjoyed it.
