This is a little tricky to explain but...
I have been trying for a while to create something which measures the amount of change in a signal, regardless of if it is positive or negative.
e.g. if a signal went from 0 to 1 then to -1 the signal would have 'travelled' 3. But I am not simply after a static number, I want something that is operating in real time.
This is where (for me at least) it get complicated, as it will need to act like a compressor having an attack, and decay, but no threshold. The measurement of the amount of change will be a number.
My difficulty is trying to imagine how the latter part of this would work. I can make the change of the signal a continuously ascending number, but I can get much further beyond this.
I know this is kind of vague, but I'm still struggling at the conceptual stage and would appreciate the input of more experienced people than myself.
Thanks for any help and apologise if the quantity of the word change in the above made you have flashbacks to America's previous election.
