hello everyone

I am making histogram analysis of brightness and loudness values using analyzer~.. the curves contain some noise.. which might derive from the noise parameter itself of the spectral data information.. so I need to subtract the noise of the analyzer~ output to brightness and loudness.. and then cooking an ad-hoc algorithm to determine, within variable ranges, whenever I have an ascending/descending curve.. I need this to make analaysis of attacks of extremely complex sounds in a spectral domain, like a violin or viola.. which contain very complex and rich spectral information and usually very linear amplitude curves, mainly if you are talking about detache or legato bowed articulatons.. so If I can do this.. probably my problem will be solved.. if you can help me with this.. I would thank you a lot, guys if you can help me.. I already implemented a dynamic treshold.. coming from some math operations on top of amplitude measuring, but still not as accurate as I need..

the patch I've done until right now follows bellow

and the histogram tool that I am using follows bellow

thanks in advance tiago morgado
