        @Tania-Ghosh you need FFT and strong paint routine skills, BUT, the paint routine is not optimized enough for such object size, hence you'll end up with a huge cpu and lags… although this might be unlocked by the upcoming SNEX integration but I am not sure of that at all... Another solution would be a RAW interface (C++), you can find info on this in the doc and a project example, but to achieve such a visualizer you'll need a strong level that I'm not even aware of πŸ™‚

        I can't help pressing F5 in the forum...

          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.

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

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

                      I believe the translation was trying to say "it's only a temporary solution". Hopefully @Rudra-Ghosh wasn't calling you a Crying Girl πŸ€–

                          @Rudra-Ghosh @Tania-Ghosh I don't think there will ever be such a thing in Hise since this is not what it is meant to do, or there will be a never-ending list of things to add, this is why I said you can make your own, Hise is open to C++ development in many different ways.

                          There's only one Hise developer, and a very very busy one, who tries to make the audio engine always better, not to say correcting flaws here and there πŸ˜‰
                          So I imagine we won't see an Audio Visualizer soon unless a charitable soul shares one πŸ™‚

                            @ustk Couldn't you make a crude audio visualiser by linking the output of a gain meter to a paint routine?

                              @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...

                                        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.
