Compare Multiple Inputs?

Is there some easy way to compare the values of a large number of inputs, to determine which among them is highest (or lowest)?

I haven't dipped into Core yet -- can you do actual C-like functions like "max()" and "min()"?

 

it's certainly possible...

this checks 2 values and outputs the highest. if you string a bunch of them together it could check a "large number." however, if it's at audio rate it's probably preferable to use core instead.

 

Yeah but I meant without a cascading bank of 400 Compare modules :|

How would this be done in Core?

 

it depends on exactly what you're trying to do - at event or audio rate, whether or not all the values are arriving simultaneously, etc. i've used an array to store 1024 values (the output of an FFT module, which gives both dB level and bin index) and then sort thru it at audio rate (you have to overclock the core cell using an iterate module) but it won't work if everything's arriving at once. if all the signals are simultaneous, i'm not sure you can escape the cascading compare modules.

 

Finding the loudest EzFFT Analyzer band is exactly what I'm trying to do. Sorting at the audio rate (or at least something faster than the control rate) would probably be a good idea -- the sort operation needs to complete within a few milliseconds.

 

the macro called "freak detector" in the ensemble i posted to the other thread *should* work with ezFFT but i haven't tried. the whole array gets sorted at audio rate, built for 44.1 Khz but could be anything really.

 

Thank you -- just got Reaktor 5.5 installed to check it out...
