Spectral Gating

[mmprod]

What is the best way to implement a spectral gating effect in HISE?

@mmprod Honestly you will probably have to roll your own C++ node for this kind of thing. @griffinboy posted an example on how to perform FFT processing a while back.

Custom c++ node.

You can get by quite easily by using the built in Juce fft:

	// FFT object
	static constexpr int fftSize = 128;
	static constexpr int hopSize = 16;
	juce::dsp::FFT fft { (int)std::log2(fftSize) };

That would create the required object. Then you'd need to write a loop process in order to call something like:

fft.performRealOnlyForwardTransform(fftBuffer.get());

I just wrote a node recently to process an audio buffer with FFT's. It works really well.
