Dancing Balls

Friday, June 6th, 2008

Just playing with Quartz Composer. Four dancing balls that bounce horizontally and vertically.

The file, dancing_balls.qtz is online here.

Audio Responsive Lines 2

Thursday, June 5th, 2008

There were a few problems with the first responsive lines that I did. Mainly related to visibility. For the lines I decided to make their visibility based on the audio spectrum as well as the volume, so sometimes they vanish altogether when they shouldn’t.

I have mostly fixed this now, it does still occasionally happen but not too often and in general it responds to all audio better than it did before. It is more sensitive overall.

There are some changes to the rotations as well so now there is more variation in how the lines appear, including the illusion of a horizon, so there is a lot more randomness to it.

I have also gone through and added in notes to make it easier to figure out what does what later on, also so anyone looking at it can figure it out relatively easily.

The Quartz Composer file, responsive_lines_2.qtz is available here.

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.

Audio Responsive Lines

Thursday, June 5th, 2008

I decided to experiment a bit more with the patches I had been using for my responsive particles to try making some audio responsive lines.

The lines turned out to be a bit harder to work with than the particles since there are quite a few more things to control, but they did produce an interesting result.

The Quartz Composer file, responsive_lines.qtz is available online here.

Note that this one involves a lot more flashing than the other’s, so if you are epileptic or just don’t handle rapid flashing colours very well, you are looking at it at your own risk.

Audio Responsive Particles 3

Wednesday, June 4th, 2008

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.

The responsive_particles_3.qtz file is available here.

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.
