iTunes VisualizerLion, QC 4.5 & iTunes Visualizers & Music Visualizer Protocol I was just wondering if anyone else had experienced the underwhelming lack of Template effectiveness regarding amending a non Template derived composition to being a Music Visualizer composition. I find that although one can start from a Template and build within that composition, going the route of build from a plain blank comp and then protocols from the Editor Menu fails to put the protocol port splitters into place. It's not as though the visualizer support has actually gone from iTunes, far from it, see attached example working in Lion and should be backwards compatible too :-)
iTunes VisualizerMy .qtz file works fine. So I bought QuartzBuilder 2.0 and exported the project ok. But when I try to launch the compiled .app i get the following error: "An unexpected error occurred (error code -10810)" and my app won't start, grrrrrrrrrrr I cannot find an explanation of 10810. Any ideas...?
Turbulent Gradients (Composition by cybero)
This is another porting of OpenCL kernels derived from the seminal noise_kernel.cl file provided by Apple as one of its Developer examples. Instead of nesting these kernels together, as can be done in the same OpenCL kernel patch, they have been deliberately separated . Each gradient kernel provides a very responsive, configurable graphical animation well suited to reacting to audio input. In this current setup, the four kernels are rendered in turn via a demultiplexer. This post is a companion to the "closed loop" version that is not set as an iTunes visualizer, but is intended to be an audio reactive loop, the inputs of which kernel can be further altered 'live'. There are a lot of possibilities with this type of gradient & I'm looking forward to creating some different texture / image creation & filtering kernels in the future. For now, do enjoy & employ this as you see fit. I'll be interested to see how they get used. Neon Audio Processor - OpenCL iTunes visualizerA screen grab of some work in progress, an OpenCL graphics kernel based iTunes visualizer. The construct is essentially one whereby the audio spectrum and peak data are separated into peak,low, mid and high , these values then being the initial values for the computation of the resulting audio reactive graphic. The bands are high, middle and low from top to bottom. Looking at setting up some presets, as the slightest change in certain of the input variables results in drastic changes to the graphic rendered.
Particle Tools - Quartz Crystal Failed Render SyndromeI've just stumbled upon a couple of possibly related Audio Tools problems. One - probably known about, but only apprehended by me since re-introducing myself to Particle Tools, as follows :- Starting & stopping an Audio Tools offline render construct, see example attached, that feeds into a Particle Scene, will result in the audio failing on the second and subsequent triggering of the audio. Two - although this construct - see posted to Repository, Particle Dance, works fine as an iTunes visualizer, it won't actually render as such in Quartz Crystal, repeatedly resulting in a Failed Render message.
