F0 difference limens for unresolved harmonics

Dear David,

In our 2001 paper we found DLs of 1.2 % for unresolved harmonics. I
guess the major difference is the "wideband" nature of our stimuli: They
were not band-pass filtered but high-pass filtered so that a by far
larger part of the cochlea would see the stimulus.
