WebThe FFT is an implementation of the Discrete Fourier Transform (DFT) that makes use of symmetries in the FFT definition to reduce the mathematical intensity required from O( \(N^2\)) to O( \( N \log N\)) when the sequence length, N, is the product of small prime factors. Currently, there is no standard API for FFT routines. WebI'm guessing this part does the smoothing and scaling I'm after in the Web Audio API: // Normalize so than an input sine wave at 0dBfs registers as 0dBfs (undo FFT scaling factor). const double magnitudeScale = 1.0 / DefaultFFTSize; // A value of 0 does no averaging with the previous result.
