Calculates the inverse fast Fourier transform of an array of numbers or complex numbers. The input length must be a power of two.
The array
const spectrum = Chalkboard.calc.fft([1, 0, -1, 0]);const signal = Chalkboard.calc.ifft(spectrum); // Reconstructs the original signal Copy
const spectrum = Chalkboard.calc.fft([1, 0, -1, 0]);const signal = Chalkboard.calc.ifft(spectrum); // Reconstructs the original signal
