	Generates three clusters of lights, one in the middle, and two symmetric ones that travel out from the center and return.

	Creates two light clusters that move according to sine wave motion, but their speed is affected by the volume. One pulls its color from fHue, and the other pulls its color from the formant values. Talk configuration combines glitch with talking_moving(). Sections configuration creates 4 seperate sine wave clusters.
void	bands (Strip_Buffer *buf, int len, Pattern_Data *params)
	Basic band config : Uses the band_split_bounce() function to generate a five band split, and maps that split to the light strip. The strip is broken into five chunks of different colors, where the volume of each band determines how much of each section of the LED strip is lit. Advanced bands config : he strip is broken into five chunks of different colors, where the volume of each band determines how much of each section is lit, and that portion will diminish over time if a certain volume threshold is not met Fomant bands config: emonstrates the formant feature of the audio analysis code. Each of the three formant values correspond to a third of the entire LED strip, where the individual formant values determine the hue of each third.

Function Documentation

bands()

void bands	(	Strip_Buffer *	buf,
		int	len,
		Pattern_Data *	params )

Basic band config : Uses the band_split_bounce() function to generate a five band split, and maps that split to the light strip. The strip is broken into five chunks of different colors, where the volume of each band determines how much of each section of the LED strip is lit. Advanced bands config : he strip is broken into five chunks of different colors, where the volume of each band determines how much of each section is lit, and that portion will diminish over time if a certain volume threshold is not met Fomant bands config: emonstrates the formant feature of the audio analysis code. Each of the three formant values correspond to a third of the entire LED strip, where the individual formant values determine the hue of each third.
