Can cross filtering be considered to be the same as convolution, similar to, or different from?

To my ear the results are in the 'simlar to' area but with more options. Can you shed a litlle light on the other differences if any

I think the short can be considered to be the same while the long can be considered to be similar to. Not sure though :)
iam curious about this as well, sean. maybe on of the synthesis experts can shed some light on this.
btw. is there a difference between a convolution reverb like altiverb and pete´s crossfilter algo?
would it change your way of using the crossfilter if you would know how it works in detail? ^^
Possibly, yes. Perhaps with more detailed understanding of what's happening you could make more informed decisions/approaches.

The abilty to update the impulse in real time is unique to Kyma AFAIK but I havent seen many sounds that explore that aspect.
The whole subject of what an impulse (or response) can be is fascinating
sean, you probably know this articles (about convolution-more in general):

and this:

the second article for example elaborates how the length of the ir effects the input.  

definetelly worth a read…
These are good reads :) I'm familiar with the tweaky article and that does give a great definition of convolution and it also says that CrossFiltering is not actually convolution though.

I think the answer is 'simillar to' and uniquely Kyma
