I have changed a few more things in my audio responsive particles again.
One of these changes is the way that the colours are generated. Now there is much more colour variation and a lot more of the smaller particles are coloured as well instead of just being grey. For the best colour variation, music with a large audio spectrum is much more rewarding than music with a small spectrum.
I have also changed the math for the size controls for the particles. The changes allow them to be bigger than they could be previously. The audio volume is multiplied by 2 and then divided by 4. Previously it was divided by 8.
This time around I have also named most of the patches so that they are more easily recognised as well as grouping the related patches and encompassing them with a note about what the group does, so as to make it easier to figure out what relates to what.
It requires input via the built in mic in Macbook’s or iMac’s. It can of course be changed to accept audio input from the microphone-in, or line-in on Mac Pro’s or Mac Mini’s. With the right plug-in, it can also accept input from iTunes.
The most ideal is via line-in or microphone in as this gives the most control over what exactly the graphics are being synchronised with. However, using the built-in microphone means that no extra accessories are required.
Note that this was done using Quartz Composer in Leopard.
