Creative Computing – Week 11 - Processing – Spatialisation

Creative Computing – Week 11 - Processing – Spatialisation:

With the onset of a brutal spring cold threatening to bring me down, I have kept things simple this week. Rather than opting for the convoluted quad channel patch examples from which to draw a template, I selected an auto panning idea that keeps things in the traditional stereo domain.

While this little effect box may appear small, its potential project inclusion is leaning toward using multiples of the unit for auto panning specific frequency ranges in the context of an FFT process. It sounds ambitious, and will probably burn a few Macs in the process, but I think it’s an interesting idea and worth pursuing.

I have included possibly my least sophisticated example track yet, but it gives a straightforward idea of how the effect works. It is basically a wave-cycle controlled left-to-right-to-left panning process, which is being manipulated by changing the frequency of a simple sine wave in this case. The tremolo effect that can be achieved in simple setups like this example is worth a listen. Future experimentation will involve feeding more complex audio signals into the pan control input.
