denorm :: [Arate] -> SignalOut

• opcode : denorm
• syntax :

   denorm a1[, a2[, a3[,... ]]]

• description :

Mixes low level (~1e-20 for floats, and ~1e-56 for doubles) noise to a list of a-rate signals. Can be used before IIR filters and reverbs to avoid denormalized numbers which may otherwise result in significantly increased CPU usage.
