For multisub systems, that is.
I read this interesting piece from Dr. Geddes in another forum:
"To ellaborate. WHen I had the idea that what was needed for LFs in small rooms was an increas in modal density, not a decrese, I looked into what electronic processing to do this would look like. I started by considering that in a dense modal region there is a randomness to the sound field caused by the fact that we have a plolethera of modes all interacting with different phases etc.. What would the impulse response of this situation look like and what would a filter look like. Turns out that the impulse response is nothing but a dcaying random one, i.e. virtually identical to reverberation. Then I discovered that this type of filter has a very precise deffinition and usage - it is called a decorrelation filter. In other words this filter decorrelates the output from the input through a reverberation type of process. It isn't a large leap to realize that what we want to do at LFs is to decorrelate the sound field since the modes cause it to be highly correlated. The reverberation signal is one way to do that, but another is the use of other sources of sound, ideally uncorrelated with each other, but if they are distributed and randomly placed then they will tend towards being uncorrelated. This could be further enhanced by using a reverb unit on all but one of the subs to uncorrelate them, but I have never tried that."
Would that be possible on the miniDSP platform to have some reverb feature (and still maintain level, delay, and some PEQ functionality)? Seems like it would be fun to play with.
Oops, sorry for the delay in getting back to you.. we missed your post!
An interesting idea indeed...Unfortunately the reverb is not available on this DSP and therefore not possible.
