Uncaught UnboundTypeError

[frantic0]

Hi @chriskiefer

I'm trying to refactor the FFT example (20-analysis-FFT.html) in the SPN version of Maximilian (asm.js).

I'm getting an exception on the maxiFFT.process call. Do you think you could have a look to see if I'm missing something?

Here's the stack trace.

I think I found the problem.

"UnboundTypeError: Cannot call maxiFFT.process due to unbound types: N7maxiFFT8fftModesE

If you look at the error above, it say that maxiFFT.process requires an c++ enum 'fftModes' as parameter which is unbound (no embinding).

check maxiFFT.h, line 47 enum fftModes {NO_POLAR_CONVERSION = 0, WITH_POLAR_CONVERSION = 1}

I'm trying to find a solution and defining the enum as embindings but that doesn't seem to be working... need to dig a bit deeper.

Hey @chriskiefer

here's my solution. I implemented it by bounding the maxiFFT enum and creating an overload to prevent dependent code from breaking.

It's set across all layers, please check. I also found some inconsistency between methods (getMagnitudes vs getMagnitude, where is the latter?)

After all this I found what is apparently a memory leak on fft... I think we need to look at this more carefully and perform some housekeeping.

}

    let myOsc2 = new m.maxiOsc();

    let fft = new m.maxiFFT();

    fft.setup(fftSize, 512, 256);

    maxiAudio.play = function () {
