curves. Another prerequisite is that the filter is able to recognise parameter jumps that exceed a certain threshold and doesn't interpolate these jumps. I realise that this is probably impossible to accomplish.
certainly not impossible, dynamics compressors/expanders operate on this concept, only mangling the signal when (or when there isnt) an abrupt change. most of them use a small blocksize-or-two lookahead to get better results.. maybe you want to involve a gate of some sort, and flip on and off the lowpass/interpolation/compression depending on some threshold of recent change..
a simple non-linear (IIR) low-pass filter is x[n]=a*x[n-1]+(1-a)*y[n] (with 0<=a<=1)
So this would basically be lop~ , but not in the frequency domain? I'm a bit confused about the y[n], shouldn't that be x[n] as well? Sorry, I'm totally new to this ...
thank you, thoralf (quite confused).
