Been checking the archives and would like to confirm the info I found.
I need a solution for a patch I'm writing.
The goal is -- Split a full-spectrum signal into 4 separate hi/low frequency
Basically, I need 4 bandpass filters where I can control the bandwidth or I
need 4 pairs of crossovers.
Whatever solution I go with, I'm looking for a "brick wall" slope or as
close as I can get.
By searching the archives, it seems the solution involves cascading biquad~
or something similar. Found an example (message #16840).
Other solutions discuss using Lossius' tl.butter* externals.
1. These posts are old. Has a more literal external been developed, like a
signal version of [split]?
2. Using either the tl externals or biquad~, am I missing how to create a
bandpass filter that has a bandwith control? i.e., a "flat-top" of defined
width? Is it possible? Or is the solution a high-pass and low-pass in
I saw posts talking about using a series of bandpasses on different
frequencies to approximate this. Is it the only way?
3. Out of curiousity, what's the standard Q/slope of an analog crossover,
like one used to split a signal between a subwoofer and regular speakers.
Is it a brick wall or close? Does it have a longer slope?
