Simple arithmetic operations in AUv3 workflow ?

Hello,

I am wondering how I could conduct basic arithmetic operations on a stereo signal in an AUv3 workflow (to process « live »).
For example, let’s say I have an incoming stereo signal L/R.
Then I want to insert it in a AUv3 FX such that the output will be :

L’ = -20%R
R’ = -80%L

So basically the possible operations boil down to :

  • channel swapping
  • negative gain

Do you have ideas of a plugging doing this in an easy way ? Or maybe it is feasible « natively » in hosts like AUM or ApeMatrix ?

Thanks a lot !

  • AUM has some of this capability via built-in operators.

  • The splitter module in NuRack has a L+R split option, so combine that with a mixer module and use the pan and gain controls to get your desired output.

  • Thanks all for your feedbacks !
    AUM seems to be the simplest solution. Just missing the mono to stereo conversion.
    Nurack - though nice - seems a bit overkill for these basic operations 😅
    Haha Drambo… 😆 Ok, I think I will have to buy this one soon anyway (just for the pleasure to reply « Drambo » to any future question).
    Cheers !
