A while ago, another member and I were talking about VU meter and spectrum type effects for displays.
We looked at some chips that took live audio in and gave out a set of voltages. That could be manipulated (via a DC or pixel controller) into bars of light to resemble a spectrum display.
Then I thought why not take a step back and have this board output DMX, so you could feed whatever controller hardware (DC, pixel, etc) you wanted with it. Seconds after that thought entered my mind, I thought why not change this to a software solution.
So, the idea is to run some software on the same PC as your sequence is running and it will listen to the audio being played. It will then split it up into frequency bands and output that as DMX or E1.31 data that you can feed to your controllers.
It might be customisable for the number of bands and if the bands are output as sets of channels (steps of a bar graph) or just one per band (variable intensity).
