ColorChord Cmake Edition #Clion

Building with Clion in Linux and Windows

Load the colorchord project. After clion finished loading the cmakelists, configure the working direktory in the build configurations that it points at the colorchord2 folder. Otherwise colorchord wont find the configs.

That's it! Hopefully : )

What is ColorChord?

Chromatic Sound to Light Conversion System. It's really that simple. Unlike so many of the sound responsive systems out there, ColorChord looks at the chromatic properties of the sound. It looks for notes, not ranges. If it hears an "E" it doesn't care what octave it's in, it's an E. This provides a good deal more interesting patterns between instruments and music than would be available otherwise.

Background

Developed over many years, ColorChord 2 is now at the alpha stages. ColorChord 2 uses the same principles as ColorChord 1. A brief writeup on that can be seen here: http://cnlohr.blogspot.com/2010/11/colorchord-sound-lighting.html

The major differences in ColorChord 2 is the major rewrite to move everything back to the CPU and a multitude of algorithmic optimizations to make it possible to run on something other than the brand newest of systems.

Current State of Affairs

Currently, ColorChord 2 is designed to run on Linux or Windows. It's not particularly tied to an architecture, but does pretty much need a dedicated FPU to achieve any decent performance. Right now there aren't very many output options available for it. The most interesting one used for debugging is a voronoi-diagram-like thing called "DisplayShapeDriver."

ColorChord: Embedded

There is work on an embedded version of ColorChord, which avoids floating point operations anywhere in the output pipeline. Though I have made efforts to port it to AVRs, it doesn't seem feasable to operate on AVRs without some shifty tricks which I'd like to avoid, so I have retargeted my efforts to 32-bit systems, such as the STM32F303, STM32F407, and (somehow) the ESP8266. ColorChord Embedded uses a different codebase, located in the embeddedcommon and distributed among the various embedded* folders.

Using

To run colorchord, use the following syntax:

./colorchord [config file, by default 'default.conf'] [any additional parameters]

If you edit default.conf while the program is running and resave it, it will use the settings in the newly saved file.
