How to create audio visualizer in HISE

[ustk]

@d-healey But in this case, you only have the amplitude content, no frequency information...

@ustk I'm thinking... the audio analyzer has frequency and gain info. We might be able to connect that data to a visualizer.

@dustbro yeah it makes use of the FFT. I tried to use FFT from the core library with no success, apparently, it's full of bugs. I don't know where the FFT of the analyzer is taken from though, probably directly from the JUCE library...

I knew I asked Christoph not long ago:

@dustbro said in How to create audio visualizer in HISE:

so the audio analyzer already IS a visualizer.....

@Tania-Ghosh Try FFT experiment with the source code. Here I have created sln file.
SFML

FFT with SFML.zip

You will also get an exe file(compiled) ... set Audio name and buffer size to up and run it.
