What I'm understanding: You write FFT results into a file so you can
always read at the end of it to get the "latest" one by reading at the
end of it ...
My advice: Don't do that ! Using files is really dumb for this
usecase. Depending on what's reading you can either use a FIFO or even
better write to a ZMQ pub sink and modify your reader to use a ZMQ
sub.
