Resonant filter
Hi just started using max msp and I want to make a resonant filter.
I made a patch with bad results...
Can you help me?
Thanks
try reson~
opeh help file and play with it.
you can delete that line freq sweeper,
and input float frequency.
max has no proper limit on GUI objects in help files,
so either set them yourself or try not to go over limits.
I used reson~ but It didn't work as expected.
Even with high "q" factors the filter through lot's of information (audio)
then what you ask for is not reson,
but very steep and narrow bandpass filter.
look into biquad~, filtergraph~ etc
help files
most simple is sfv~
Thanks guys. svf~ right?
I tested svf~ but I, even with 1 value as resonance, I can hear the components of the dry signal...
I'm in band-pass mode.
In this way I can hear the result I'm looking for but I need multiple objects and space on the screen
you can make gui smaller,
or if you use fixed settings fot freq, gain, q,
simply loadbang blue message to biquad~
and remove the rest
Thanks. Can I send the fixed settings without using the filtergraph~ object?
you can use filtercoeff~, filterdesign~, or put filtergraph~ into a subpatch.
you can even program your own control signals using msp or max objects for such a filter... if you can.
or you can program your own control signals, for example also in another program such as matlab, and load the control signals into a buffer and read them from there at not much CPU.
however, graphical feedback is very useful while programming - so that you see what you do or why it does not work.
and that not only for beginners but also when programming your own coefficients. (filtergraph~ can also be used to only display data for exactly that reason.)
Thanks a lot for your suggestions guys : )
