You could just change the part of the array that gets read, that might
be easier.  I don't use sampling much.  Miller Puckette's book
http://crca.ucsd.edu/~msp/techniques.htm addresses samplers in Pd at
length, just something to look at some time, it's pretty thick.
I think either way you'll have to search for loop points yourself to
eliminate the clicks.

What kind of sound?  For a steady note, or something like speech?  For
speech you'd want to look at [rfft~]...  A confusing subject, but fun
to do with Pure Data.
