Sound Reactive Animations
Note 1: Effects beginning with ♪ (* in list below) are volume only.
Note 2: Effects beginning with ♫ (** in list below) use FFT (Fast Fourier Transforms) for frequency detection.
Note 3: We have also not added 2D animations to the ESP8266 platform. ESP8266 is depricated in SR WLED, so we recommend that you use ESP32.
Note 4: The 2D routines require a minimum of 4 pixels in both directions. If you see blinking red, your 2D settings don't match the requirements. (not required in latest dev)
Note 5: As we continue to develop SR WLED, some animations may appear or disappear. It's still a work very much in progress. Some may only appear in the dev branch for now.
Note 6: In dev branch, sliders have been renamed from FFT Low to Custom 1, FFT High to Custom 2 and FFT Custom to Custom 3.

Slider Usage
Please see the brief slider descripion for each effect in the rightmost column above.
Speed/Intensity
These typically reflect the value of their namesake. Intensity would typically be number of LED's lit, or brightness of the LED's
FFT Sliders
These may get renamed in the future and could be used for FFT routines OR for additional effect adjustments.
Peak Detection
This is NOT beat detection, but rather samples that are louder than a the current average plus a slider adjustable value.
Automatic Gain Control
We are just beginning to add Automatic Gain Control to the routines, starting with 2D Swirl. This setting is only available on the LED Preferences page on the ESP32.
FFT Routines
Additional effect notes
Freqmatrix
The temporal tail for this animation starts at the beginning of the Segment rather than in the center of the segment.
Sliders used:
Slider usage is described in the rightmost column for each effect. In general, the sliders are configured for:
- Speed: This determines the time delay before each pixel is moved down the line.
- Intensity: This determines how MUCH the sound input affects the selected effect.
- FFT Low: Can be an additional adjustment. Can also select low end of frequency bins if used by that effect.
- FFT High: Can be an additional adjustment. Can also select high end of frequency bins if used by that effect.
- FFT Custom: Can be an addiitional adjustment.
Freqwave
This effect maps the major frequencies from the incoming signal to colors in the HSV color space. From the low notes being mapped to red (0) to the high notes being mapped to blue (255) and everything in between. The band you are looking at can be restricted by the FFT Low and FFT High sliders. We are digitizing at 10240Hz, meaning the highest frequency bin that you can find is 5120Hz, which for most music is just fine.
Sliders used:
- Speed: This determines the time delay before each pixel is moved down the line.
- Intensity: This determines how MUCH the sound input affects the selected effect.
- FFT Low: The low cut off for the FFT bins. Values range from 0-100. Good values are from 0 to 10
- FFT High: High cut off for the FFT bins. Values range from 0-100. This is important because every type of music is different and what is considered a high note in one type of music is not the case in others.
- FFT Custom: This slider works similarly to a "pre-amp" for the input signal. The possible values for this slider are 1-10. A good starting point for this is around 2-3.
