1e-20 ( ~= signal at -400db ) should be inaudible enough.
Denormals start < 1e-31 (~ -620db).
I think it's almost always a better idea to add an inaudible DC offset
or a square wave at the block interval or at Nyquist
How small is inaudible? Or better yet, how small is way beyond inaudible,
but enough to eliminate any denormals? The other problem is locating exactly where the
problem exists: I'm using
Faust <http://faust.grame.fr/> to generate the reverb DSP code, so
injecting DC offset would involve me tinkering with the reverb algorithm.
I'd prefer leave it alone, but the outputs of the reverb can be DC-offseted
easily. I don't think that would be enough... since the denormals could /
would also exist internally in the reverb algo?
You should to add it to each sample on the input, before the signal
enters the effect.
