multichannel sound enhancements: compression, limiter


    Jan 24 2009 | 11:19 pm
    Hello list,
    Currently I am working with multichannel live input. Is there a semi-simple method/patch/object/vst that does compression, limiting, expansion or other similar processing for multichannel input?
    to my knowledge and experience most compressors and limiters do not take more than two inputs at the same time. This is because all the channels have to be considered and modified simultaneously so that the overall image/balance of the input doesn't change.
    Any help/advice wold be appreciated.

      for more clarity. here's a hardware equivalent of what I am looking for to use within max patches: http://www.kellyindustries.com/signalprocessors/presonus_acp88.html
      "It's also capable of linking any number of channels via the power summing bus. Power Summing Buss Linking is great for dynamically processing stereo and other multi-channel sources where each channel processes using the same settings. It's enabled by pressing the LINK button which will link together this channel to one on its immediate left. "

      Look at komp-multichannel.maxpat in the examples folder. This shows an easy way to sum multiple signal inputs and route them to multiple compressors which all share the same settings. The komp abstraction could be replaced by your favorite vst. You might also try different flavors of averaging the input signals rather than summing them.

      thanks for the pointer, komp-multichannel patch didn't exist under max 4.6 examples.
      I also found an object called "tt.limiter~" that takes an argument for the number of channels to process.

      I would recommend checking out Tap.tools 3:
      The tt externals used in Jamoma is just a small subset of Tap.tools.

      I have it
      tt.limiter~ = tap.limi~
      best, -Nav
