Classes
class	FFTEffect
	Abstract base class for effects that operate on audio in the frequency domain: incoming samples are transformed with a forward FFT, the resulting bins are modified by the effect() method that a subclass implements, and the modified spectrum is transformed back with an inverse FFT (overlap-add) and streamed to the output. More...
struct	FFTEffectConfig
	Common configuration for FFT effects. More...
class	FFTEqualizer
	Graphic Equalizer implemented as an FFT effect: boosts or cuts logarithmically spaced frequency bands (20Hz .. Nyquist) by scaling the magnitude of the bins that fall into each band while leaving their phase untouched. Since this operates directly on the frequency-domain bins rather than an FIR/IIR approximation, band edges are exact and there is no filter ripple. More...
struct	FFTEqualizerConfig
	Equalizer FFT Effect Configuration. More...
class	FFTNop
	Apply FFT and IFFT w/o any changes to the frequency domain. More...
class	FFTPitchShift
	Apply Pitch Shift FFT Effect on frequency domain data: we just move the bins up or down. More...
struct	FFTPitchShiftConfig
	Pitch Shift FFT Effect Configuration. More...
class	FFTRobotize
	Apply Robotize FFT Effect on frequency domain data. See https://learn.bela.io/tutorials/c-plus-plus-for-real-time-audio-programming/phase-vocoder-part-3/. More...
class	FFTWhisper
	Apply Whisper FFT Effect on frequency domain data: keep the magnitude of each bin but randomize its phase. See https://learn.bela.io/tutorials/c-plus-plus-for-real-time-audio-programming/phase-vocoder-part-3/. More...
