experiment based on good ole noise and feedback- many different looks can come from slight changes to the many published parameters plus further dynamic changes and processing in VDMX , Resolume, Magic Music Visuals, etc. Tested with VDMX June 2021 version.
Note: adjusting FBxySlide. Parameter the comp can be made to continually slide vertically (like an escalator),horizontally or staying in the same position.
This is a typical stereoscope. The basic maths behind it is VERY simple. However I added a bunch of frills that may make it more useful for video artists. Remember that to use a stereoscope you need to have a stereo audio signal (too obvious?). So if your input is the laptop mic for example, it won't work. You'll have to have audio coming from a stereo line input (if you have one), or routed internally using something like soundflower.
Here's another spectrum plug I made using a different approach. Unfortunately this is even less accurate, but it looks fun and is useful as a visualizer. Here I have the "Calculate Amplitude for Frequencies" set to "quadratic", which arranges the bin values decently enough that they can be processed in an even row (In the previous composition I spaced the bins exponentially). With the bins spaced linearly they can then be processed as scalable rectangle layers. If anyone knows a good way of taking the bins and then reprocessing them into more accurate data then please let me know.
