If I assume correctly  that you are trying to process live input you should
use the adc~ object which has 2 signal outlets for the right and left channel.

the status window and the tutorial patches in the doc directory should get 
you started here, basically fft~ puts out numbers suitable for consumption
of the ifft~ object, there are tutorial patches on that.

there are netsend/receive objects that enable communication via sockets (tcp 
or udp) , on unix a named pipe (mknod /tmp/mypipe p) would be another option, 
writing an external hmmm .. anything else ?
