Isolating Frequency Ranges

January 21, 2011 | 10:55 pm

Hello Friends,

I’m trying to create a patch that will allow me to separate frequency ranges from an .aiff file so that I could route the signal of a specific range (like bass) to another object. I’m a little lost with this one so any ideas or suggestions would be appreciated.

This might be a start, though the filters will probably sound louder combined around center freq:

put simply, use a passfilter (higpass or lowpass), and then substract the result
from the input signal in order to get the other half of the input.

Roam, that’s a nice and simple idea. Should be easily feasible to modify my example patch above into working without overemphasizing the center frequency.
Thanx for reminding me of phase reverse benefits.

Try [cross~].

This is what a crossover is for.
