Classes
class	fl::audio::fft::Impl

Namespaces
namespace	fl
	Base definition for an LED controller.
namespace	fl::audio

Functions
bool	fl::audio::fft::detail::coverageFloorApplies (u32 fftMag, u32 cqMag, u32 localCqMax) FL_NO_EXCEPT
	CQ_OCTAVE coverage supplement decision (FastLED#4301/#4540), integer form used in FIXED16: the full-rate FFT floor (fftMag / 50) replaces a CQ band's magnitude cqMag only when no CQ band within one FFT main lobe detected energy (localCqMax < 20) and the floor is strictly larger.
