Sorry, the filesize is my mistake. All okay now. Thank you.

Subject: Fw: [Discuss-gnuradio] Odd behaviur of "Fractional
Interpolator" Uhm, so it’s a little bit confusing.
Another strange problem is that if i put a 0.64 value of interpolation, and
my flow graph is a file souce->fractional interpolator->file sink, and my
source file is 1GB of data, i’m expecting a 1GB*1/0.64 output filesize. But when
i run the graph i get a 800MB of output filesize, minor than the source file. I
cannot undestand this...
Thank you.
