[svf~] frequency range

November 24, 2008 | 11:55 am

good morning,

i am working on a filter feedback patch using [svf~], turning the filter resonance all the way up.

just listening to the results i found, that about the highest feedback frequency i could produce was around 8 or 9 KHz, now i am reading, that svf~ is capable of covering a max. frequency rate of 1/4 of the sample rate. my audio interface cannot work with more than 48 KHz, which would give me a max of 12KHz audible filter range.

Is there a way to internally "up-sample" the sample rate at the beginning of a signal chain to extend the frequency range of svf~? (i know, how to down-sample…)

thank you very much in advance.

a poly~ object can do upsampling. look into the "up" message to a poly~ object.

THANX A BUNCH!
