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.Read Review
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).Read Review
