Also, anyone thinking of audio VU meters, check out the MSGEQ7 chip if you have not already, i have a dozen or so from this seller : http://www.ebay.co.uk/itm/270847592314 (not related) and used some in a work project (audio -> DMX) and they worked wonders, nice stable DC level out for reading by a micro ADC. There is another (harder to find) MSI chip that has all 7 channels broken out so in theory a 7 channel VU without a micro would be easy, that chip and some op-amp / high voltage transistor glue. A micro + DAC's would allow some nice winamp swooshey effects in between songs though as well :-)
