Procedural Audio: Rain System
Hi Guys,
As part of my final masters project I am trying to build a procedural audio weather/storm patch based on the work of Andy Farnell. I have created the first part of the system in the patch below with my own alterations from Andy's work. I'm wondering if any of you have any advice how I might smooth out the sound as it's quite harsh and is actually more like a crackle rather than rain. but I'm still new to max and I'm not sure how to go about it.
I also need to create short blasts of white noise that can randomly retrigger. I'm not 100% about how to get short (m/s long) blasts of sound from noise~, is there a function to switch it on and off periodically in order to achieve this?
you dont even understand what you want to copy?
I'm not attempting to directly copy their work but I have to use academic research as basis for development. The only thing I want to take from Verron is generating individual droplets in 3 categories. All I need to know is the start of the process really which is how I can get a chirped noise impact. I tried using adsr on a noise~ to create blasts of sound a few milliseconds long but it didn't work very well and just wondered if anyone was able to help. Sorry if I didn't word that brilliantly in the beginning. I really am completely new to Max so I'm just a little lost on where to start but have a pretty good idea where to go once I have a sound to work with
hm, I must admit I thought something similar as roman. The procedural modeling thing is a huge and sometimes hard topic, and not knowing how to amplitude modulate a signal seems to imply that you don't know what you're doing ;) Anyway, I don't mean to insult you.
You could take a noise~ and multiply it by some signal. An adsr for example, or a filtered impulse(see click~) if it has to be really short. slide~ might be your friend when you create an impulse that has some length and you want to control its attack and release times.
You could also build something in gen~. Or you could use click~, +=~ and delay~ to build a custom small pulse generator with adjustible hold time in the signal domain.
