asm.js FFT module

---

Usage

Creating FftModule

var fftasm = new FftModule(num fftsize, boolean enable-asm);

• Codes are compiled in this phase.

Execute FFT

fftasm.fft(Array real, Array imag, boolean normalize);

• here the real/imag are input data (Array or TypedArray)
• real/imag array size should be matched to [fftsize].
• real/imag will be overwritten with the results.

Execute FFT & get magnitude

fftasm.fftmag(Array real, Array imag);

• here the real/imag are input data (Array or TypedArray)
• the result will be placed to [real] array.
