[sdiy] Filters

[Dave Krooshof]

About 12 dB vs 24 dB/oktave filters:

I used to think I liked the 24 dB better as they are more resonant.
But while making filters, I found out that I like the 6dB even more.
My feeling is LPFs are not used to reduce overtones, but rather
add a certain range of meaningfull overtones.*
So I found myself pre distorting, then filtering.
I found I liked a resonant filter, yet I do want the freqs above the
filter to be present for brilliance. 24dB is just too "sinusidal" for me.

Then again, it's the world of sinusses that is so apart from the
phisical world that it sounds alien to us.
24dB might be the fascination of the other.


How do you guys think about filtering? what is it, what does it do for you?

*I would like to see a brain scan of someone listening to a filtered synth.
Would it show that the speech centre is lit up, as happens when listening
to song?
