FilterDeMystifier (no mysteries, just math) is a filter plug-in for educational use. It will show you how a few poles and zeros define the sound of equalisers or vocal filters.
Everything is visualised and you can see the transfer function and the resulting magnitude z-plane in a rotatable 3D plot.
Check out the presets to see what can be realised with this straight-forward GUI.
Please be aware that this plug-in can generate very unpleasant sound, if the security measures are switched off.
Have fun and read the manual, if you are interested in digital signal processing.
The source-code is available at: https://github.com/ArnoSchiller/FilterDeMystifier
It started as a course work for the final exam in DAFX (Digital Audio Effects) at our University (Jade Hochschule).

Thank you for this brillant tool! I'll be using it in my lectures from now on - of course providing your name as a source.

as quite a newb dev I'm excited about this plugin release because it might help me learn about IIR filters in a more practical way. All this dsp literature is just... nope. I mean it's important. But there really should be more of a bridge between the literature and the practical sense in a way and I think this plugin might be a good step towards a future where learning filter design is more accessible to a generic audio developer who is not super specialized in math (yet).

Nice idea! Finally a plugin which shows, what an EQ really does to your signal. I especially like the phase plot.
Read ReviewDear Simon C, .
could you please use discussion and not review for this kind of response (and perhaps delete your one star review, which has nothing to do with the plugin but with installation issues.), since I cannot answer to reviews.
I just tried AU Lab from Apple and everything worked fine (Could you check that, AU lab is freely available from Apple). Since I have no access to Logic I cannot test the plugin against it. If AU Lab fails, we have to look for other reasons.
Best Joerg.
Hi Joerg.
Sorry about my previous 'review', they've deleted it now. I haven't got AU Lab but I'll give it a go. Would be interested to see if anyone got it working in Logic.
Thanks anyway, it looks very interesting.
