Here's an example. Just replace voice.wav in function table one with
your own soundfile. Make sure you either place the soundfile in the
same directory as the csd file, or provide the correct path to your
soundfile.

sr = 44100
ksmps = 64

;randomly access samples from ft1

;write them to table ft2

do you mean a function table with audio data, as rory assumed, or a  
function table with other (fewer) values?
for the usage of the opcodes, this may help:

if you don't want any replications, this can perhaps be useful:

you could, for instance, use just the first N members of the permuted  
table.
