hey pd,
i'm trying to do feed forward in pd. i think i'm tired and not thinking this through...
so, i have a [blackbox~] that does stuff to the audio. it uses feedback internally and is currently a bit unstable. can i make it more stable by going like this:
[...] [r~ fb]
| |
| [*~ -0.1]
| ______/
|/
[blackbox~]
|______
|
| [s~ fb]
|
[...]
is there some funky combination of delays i can achieve this? i get the feeling this only works in analog electronics because you can say that on some level everything happens at exactly the same time - the delays inherent in digital systems mean that this doesn't work...
what alternative DSP techniques are there for damping unstable feedback loops?
thanks d
