Discrete Fourier transform (DFT) with the Goertzel algorithm.

Functions

Function Description
goertzel Computes the DFT of an array of real numbers and returns the complex result.
goertzelSingle Computes the DFT on an array of real numbers for a single frequency.
goertzelSpectrum Computes the complex spectrum of an array of real numbers. The result is the normalized lower half of the DFT.
