Modules
	CMSIS
	FFT using CMSIS.
	FFT-Window
	FFT Window Functions.
	FixedFFT
	FFT using fixedpoint-fft (https://github.com/pschatzmann/fixedpoint-fft)
	KISS
	FFT using KISS.
	Real
	FFT using Real FFT.
	esp32-dsp
	FFT using esp32 esp-dsp library.
	esp32-fft

Classes
class	AudioFFTBase
	Executes FFT using audio data privded by write() and/or an inverse FFT where the samples are made available via readBytes(). The Driver which is passed in the constructor selects a specifc FFT implementation. More...
struct	AudioFFTConfig
	Configuration for AudioFFT. If there are more then 1 channel the channel_used is defining which channel is used to perform the fft on. More...
struct	AudioFFTResult
	Result of the FFT. More...
class	FFTDriver
	Abstract Class which defines the basic FFT functionality. More...
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.
