Friends | |
| class | AudioFFTBase |
LEDOutput using the FastLED library. You write the data to the FFT Stream. This displays the result of the FFT to a LED matrix.
|
inline |
Default Constructor.
| fft |
|
inline |
Provides access to the actual config object. E.g. to change the update logic
|
inlinevirtual |
Returns the magnitude for the indicated led x position. We might need to combine values from the magnitudes array if this is much bigger.
