this is a simple question -

we are interested in doing fft on voice recordings.  to date we have
found we need to use a sampling rate of up to 44k, and we have been 
limited to a 4096 point transform which can leave us with a bin size
of 11 herz, clearly unacceptable for our purposes.

does octave have capability to do something like this?  
can it actually reduce bin size to something under 1 hz?
what kind of input does it need?  if we are looking at a 3 second sample
with 44000 values per second, can it actually read the program output, or
is it necessary to type in the 132000 values?


thanx
