fft core library module

@Christoph-Hart Could you elaborate on "high-level usage of FFT tasks"?

Mainly will we be able to analyze a signal and detect gains of specific frequencies?

I have the most ridiculously sweaty idea for introducing RR functionality in a static sample using modal resynthesis and residue, both of which necessitate being able to identify the loudest frequency(s).

[Christoph Hart]

With high-level usage I mean that you don't know how the FFT works, you just use it. Something like this:

block b;
SnexFFT fftObject;

void prepare(PrepareSpecs ps)
{
    fftObject.setImplementation(FFT::IPP);
    fftObject.setMaxFFTSize(ps.blockSize);
    fftObject.setScaleToNormalise(true);
    fftObject.setOutputFormat(FFT::Amplitude);
}

void process(ProcessData<2>& d)
{
    // Transforms the first channel of the signal to the fftBuffer
    fftObject.forward(d[0], fftBuffer);

    int maxIndex = 0;
    int counter;
    float maxValue = 0.0f;

    for(auto& s: fftBuffer)
    {
        if(s > maxValue)
        {
            maxValue = s;
            maxIndex = counter;
        }

        ++counter;
    }

    double freq = (double)maxIndex / (double)fftBuffer.size() * nyquist;
}

All these methods are purely theoretical at the moment, but it will look something like this (so basically just a wrapper around the C++ FFT classes that HISE is already using).

Sweeeet officially bought a ticket on the hype train

[Christoph Hart]

The hype train just got a new logo:

Not using the circles as cable end points is such a missed opportunity that I don't know how I could have missed that in the past...

[ustk]

@Christoph-Hart Is the C a modulator or is it the P ???

[Christoph Hart]

It could also be a send connection:

Or a xfader connection:

Cables!

@Christoph-Hart Can’t wait for a t-shirt

[Christoph Hart]

Good idea. The t-shirt will either have this logo or "Crashy, the scriptnode robot":

@Christoph-Hart (scriptnode logo) love it!!!!!!!!! Really pro. Just try zooming out to see if small sizes are ok. Otherwise you can make a simpler version with just one wire..... Sorry.... Can't help. Worked in advertising for 20 years

@Christoph-Hart Looks (and I am sure it also sounds) Amazing! I really like it, congratulations, as always..

NOOOOO! Now I can't unsee it.

count me +1 for a t-shirt -

You always had this as a plan right? - make a truck of money from t-shirt sales and nearly nothing form the software?

@Lindon I thought the strategy was to become a guru and teach how to make money with software sales

thats all part of the grand lie that is HISE!! HA hA ! I a=have you now!! uncovered for the scoundrels you all are with your free fully functional software that I can use to make a living - all the while trying to get me to buy your lousy t-shirt!!

lousy t-shirt

The T-shirt is just the beginning. My actual goal is a clothing line that takes over the entire fashion industry and I heard that creating a nerdy open source framework is a shortcut to get there faster.

Now that's just the behaviour of a megalomaniac - and I should know...

@d-healey underrated movie tbh
