A combination of the Skip Head and Head blocks will give you the desired
result.
[Source] -> [Throttle] -> [Skip Head, Num Items=samp_rate*3] -> [ Head, Num
Items=samp_rate*5 ] -> File Sink
This will Skip 3 seconds and record 5 seconds. Within the Options block, set
the flowgraph to be "No Gui" and "Run to completion".
