cpu friendly peak limiter ?

July 25, 2012 | 10:00 am

hi,

I’m looking for a peak limiter, for protecting 14 output channels from clipping.
I’ve tried the komp-multichannel patch from the examples – but couldn’t get it to work as a brickwall limiter.
omx.peaklim~ is too cpu-expensive, because I would need 8 instances…

It doesn’t need to sound very good and using the sum of all channels as a sidechain input (like komp-multichannel) would be ok.
It’s just for safety…

Any ideas ?

cheers,
jan.

have you tried limiting your signals using lookup tables?

@sanifok

like putting linear growth of db values as a condition to check — for substracting db level after that positive condition occurs ?

Provided your signal levels are already ‘in the ballpark’, you might even consider overdrive~. Should be pretty easy on the CPU at least…

Edit: just realized the OP is now pretty old…
