Hi everyone! I would like to ask for help with this noise detector plugin made by Sazanami. I tried to read the instructions but didn't quite understand how it works. My apologies of having not experience with JavaScript at all!

Basically, say, if I want to detect a level 5 sound (80db, as the plugin says) and it activate a certain switch (this part can be configurated in the plugin parameter and I understand). How could the detection be done with plugin command?

Also, if I understand correctly, this plugin will only turn on/off one variable - is this correct? Is it possible to make it work with multiple variables according to different sound levels? (say, level 4 - variable 1, level 5, variable 2... etc)

Thank you very much for your help in advance!

Here is the plugin:

It is a pretty old post and I thought it might be better to start a new thread here? If this is not correct, please let me know!
