- convertFFTBinToFrequency
`float`convertFFTBinToFrequency`(float fftBin, int fftSize, float samplingRate)` Converts a FFT bin to a frequency.

- convertFFTBinToFrequencyInv
`float`convertFFTBinToFrequencyInv`(float fftBin, float invFFTSize, float samplingRate)` Converts a FFT bin to a frequency.

- convertFFTBinToNormalizedFrequency
`float`convertFFTBinToNormalizedFrequency`(float fftBin, int fftSize)` Converts a FFT bin to a normalized frequency.

- convertFFTBinToNormalizedFrequencyInv
`float`convertFFTBinToNormalizedFrequencyInv`(float fftBin, float invFFTSize)` Converts a FFT bin to a normalized frequency.

- convertFrequencyToFFTBin
`float`convertFrequencyToFFTBin`(float frequencyHz, float samplingRate, int fftSize)` Converts a frequency to a FFT bin.

- convertFrequencyToFFTBinInv
`float`convertFrequencyToFFTBinInv`(float frequencyHz, float invSamplingRate, int fftSize)` Converts a frequency to a FFT bin.

- convertNormalizedFrequencyToFFTBin
`float`convertNormalizedFrequencyToFFTBin`(float normalizedFrequency, int fftSize)` Converts a normalized frequency to a FFT bin.

- forwardFFT
`void`forwardFFT`(BuiltinComplex!T[] buffer)` Perform in-place FFT. Equivalent to

`std.numeric.fft`, but this one is nothrow @nogc.- inverseFFT
`void`inverseFFT`(BuiltinComplex!T[] buffer)` Perform in-place inverse FFT. Equivalent to

`std.numeric.inverseFft`, but this one is nothrow @nogc.

- FFTAnalyzerstruct FFTAnalyzer(T)
From a signal, output short term FFT data. Variable overlap. Introduces approximately windowSize/2 samples delay. Uses a real FFT to gain some speed.

- RFFTstruct RFFT(T)
Perform a FFT from a real signal, saves up CPU.

- Segmenterstruct Segmenter(T)
From a signal, output chunks of determined size, with optional overlap. Introduces approximately windowSize/2 samples delay.

- ShortTermReconstructionstruct ShortTermReconstruction
From short term windowed data, output the summed signal. Segments can be irregular and have different size.

High-level interfaces for providing FFT analysis, real FFT, and resynthesis from grains.
