Dear csounders,

I am curious about the fofilter opcode. I am wondering a bit about different ways to use it. Is there a (simple) way to figure out how to create different vowel sounds for instance? Does anybody have examples, other than the one in the manual?

Anders

Hi Anders,

there is a chart of formant frequency and bandwidth values in Csound manual.

http://www.csounds.com/manual/html/MiscFormants.html

That way you can type in the numbers in the chart to create different vowels. 

Best,

Marvin

Thank you, Marvin!

I have seen those tables but as I understand it, they are for the fof/fof2 opcodes but not for the fofilter opcode.

No, they are just formants, you can use it in any setting

It’s a band pass filter. You set the frequencies, then the rise and decay times

for the impulse response. The rise time

is just like kris in FOF and the decay time

is inversely proportional to the bandwidth.

Ah, yes, they are general formants defined by their frequencies and bandwidths, but how do I relate that to settings for fofilter? Or what’s is fofilter supposed to do really?
