Equalization & processing questions


    Jan 17 2006 | 4:20 am
    I'm looking for suggestions on a couple of EQ considerations...
    I have a Max-MSP project that will be performed as an installation.
    Once it leaves the "womb" of my studio I expect to have to do some
    EQ-ing once it's in the space and the room's natural acoustics take
    effect.
    The first question is whether it's advisable to stick with Max-based
    EQ options or use outboard gear. I've never done any sort of EQ-type
    processing in Max and don't know how intensive it can be.
    This piece uses 4 poly~ objects. If I do proceed with EQ inside Max is
    there a way to create a master EQ that will effect the entire mix?
    Right now, each poly has four outputs (for a quad speaker set-up) and
    is routed to four inputs in the dac~ object. I don't want to have to
    use four separate EQs here--how can that be avoided?
    The third part of the question is about the EQ patch itself. Can
    someone please recommend a stable, good-sounding EQ that is available
    either as freeware or shareware for Max.
    I would also consider using one of my VST EQ plug-ins if these kinds
    of things will run reliably.
    Thanks to all in advance!

      honestly, i would suggest to keep your project
      untouched and your cpu not to full blast, i don't know
      about the complexity of the processes that you're
      getting performed by your machine , but i think that
      can't hurt to consider that. basicaaly i would eq the
      analog output tahat feeds the pa with a graphic analog
      eq (a 31 band i.e.), just to keep it simple. let me
      know what you'll end up doing. ciao, R.

      You could have a look at peqbank~ here:
      Put it anywhere in the signal chain you like. Seems like you want it immediately before the dac~.

      Can be straight forward with a combination of Filtergraph~ and biquad~
      or cascade~, Max or outboard i always a matter of taste and/or budget.

      You can' avoid that, but you could control all four with the same
      Filtergraph~.

      That should be no problem either
