The 'normal' gain for a reverb IR would be such that the direct sound,

that the IR was taken with a source to mic distance that produces a good
direct/reverb ratio.

Another way to get reasonably good levels is to measure the gain
using pink noise. Measure input and output with a RMS meter such
as jkmeter. Note the difference, and adjust the gain in the config
accordingly.

Not that any distorition you hear is not produced by jconvolver,
since it uses floating point. It just means that you are driving
your DA converters to high.
