I think it actually depends on your sound card whether or not this is true with Pd. I might be mistaken but I am pretty sure some sound cards will let you output abs(x) > 1. Hmmm actually this doesn't make sense to me if the driver is accepting a 16 bit signed int. Can someone confirm whether this is the case?

Incidentally, if I recall correctly, Miller told me that he uses a set of small, cheap speakers when doing experimental stuff so as to save ear damage. At least I think it was Miller.

My own ears are a lost cause after years of punk gigs so I don't have this problem.

Cheers,

Chris.
