How to create audio visualizer in HISE

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.

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

@Rudra-Ghosh Wow !!.. Nice. Thank you :)

But this is not an audio visualizer

[A Former User]

Hahaha.... exactly.... (y) ... 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]

@Rudra-Ghosh Who is Crying? I am asking HISE developers to make such Audio Visualizer.

[Dan Korneff]

@Tania-Ghosh said in How to create audio visualizer in HISE:

Who is Crying?

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

[Tania Ghosh]

@dustbro Oh.. :)

[ustk]

@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 ;)
So I imagine we won't see an Audio Visualizer soon unless a charitable soul shares one :)

[d.healey]

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

[ustk]

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

[Dan Korneff]

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

[ustk]

@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...

[ustk]

I knew I asked Christoph not long ago:

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.

[Tania Ghosh]

@Rudra-Ghosh Thanks :)
