@Tania-Ghosh My pleasure.. have a happy HISE.

@Tania-Ghosh You need to do one little thing. The latest version (as far I know) you have to locate the proper directory structure of IPP. What @Christoph-Hart described at the Projucer field is bit out dated (perfect for old IPP).But if you use the latest v 2020 or 2021 Intel Performance Primitive.
Update this location

``/opt/intel/ipp/lib/libippi.a  /opt/intel/ipp/lib/libipps.a /opt/intel/ipp/lib/libippvm.a /opt/intel/ipp/lib/libippcore.a

And update the Debug and Release configurations (Actual directory structure where IPP has been installed) Header Search Paths and Extra Library Search Paths.

Otherwise Xcode will not find IPP and will throw error.

@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.

Hahaha.... exactly.... ... Unfortunately, right now there is no option (such Visualizer) in HISE. Till then it's like "getting a sugar candy for a crying girl"..

@Tania-Ghosh Till then use image Sequences (Stitched) as Audio Visualizer.

ZGameEditor

Which is pretty good for such things(used by ImageLine as ZGameEditor Visualizer). But it needs Embarcadero Delphi or Free Pascal.
May be in Future you will get such integration to create your own visualizer in HISE.

@alepan Nice.. Good work
