-- added check for NANs

-Below some notes taken from Freeverb readme:
--------------------------------------------------------------------------------------
-
-Note that this version of Freeverb doesn't contain predelay, or any EQ. I thought
-that might make it difficult to understand the "reverb" part of the code. Once you
-figure out how Freeverb works, you should find it trivial to add such features with
-little CPU overhead.
-
-Technical Explanation
----------------------
-
-Freeverb is a simple implementation of the standard Schroeder/Moorer reverb model.
-I guess the only reason why it sounds better than other reverbs, is simply because
-I spent a long while doing listening tests in order to create the values found in "tuning.h". It uses 8 comb filters on both the left and right channels), and you
-might possibly be able to get away with less if CPU power is a serious constraint
-for you. It then feeds the result of the reverb through 4 allpass filters on both
-the left and right channels. These "smooth" the sound. Adding more than four allpasses
-doesn't seem to add anything significant to the sound, and if you use less, the sound
-gets a bit "grainy". The filters on the right channel are slightly detuned compared
-to the left channel in order to create a stereo effect.
