Doesn't hurt here*. I guess we're getting into a subjective realm-- but if
someone adjusts their master volume for [osc~ 5555]---[dac~] to be as loud as
possible without being uncomfortable, I have a hard time believing that they
would be comfortable with [noise~]---[*~ 999999]--[clip~ -1 1]--[dac~] at that
same master level.

* I adjusted my master volume so that the clipped noise was at a tolerable
volume, then checked [osc~ 5555]--[dac~] at that same level.
