EngineersFilter - high order IIRs - sneak preview

[Music Engineer]

some time ago, i implemented some high order IIR filters that are commonly used in dsp engineering tasks. such filters are actually not commonly used in musical applications all by themselves as standalone filters. they are more likely to occur 'under the hood' inside some dsp algorithms, for example, as anti-aliasing filters. however, for proof of concept, playing around and testing, i implemented them as plugin:

i'm not quite sure what i will do with it (release as freebie or commercially or not at all), but i thought i might post a sneak preview here to collect some comments. so let me know what you think - is it useful ...or not that much?

warning: when tweaking the parameters while auditioning / running some signal through the filter, loud pop- and crackle noises occur. this is not meant to be used as a time-varying filter.

ahh, and currently it supports only mono.

I like it a lot. Good title for it. I think it's good as it is now.

I used the high pass on a synth on a track, no crappy filtery remains, it just fit in well.

It was free, it would be my favorite, if it was cheap, I would probably buy it. If it wasn't cheap, I would make do with lesser plugins.

grabbed....

i'm honestly BEGGING you to make some synthedit modules....
they are a great way to implement dsp theory and test a bit of code in a flash....

once i have all the in/out set and i compile it once, load it in synthedit, i can switch on "reload synthedit sdk modules" and reload my module every time i recompile it, so i can keep tweaking the code and testing in realtime....
pretty slick,......

I found the highpass can get high on cpu, especially when the order is high.

When playing, it was at 0.2% cpu, stopped playing, and it went up to 15%.

smells like a denormal issue. i will look into it. thanks for the notification - and also for your former general comments.

well, to be honest, i actually don't really want to see my dsp algorithms show up in every other freebie. i would be shooting myself in the foot. ..i would love to live in a world where i can have a decent living while giving away everything for free. but unfortunately, this materialist world forces me to think in commercial terms - at least to some extent. it really sucks, but i have to pay my bills.

thanks Robin

ill give it a shot

Another interesting plugin from you. Pretty cool. When I was doing my studies I remember thinking some of those super high order filters we used for non-audio tasks might be fun to play with on audio. Now I know.
