Dear Gnuradio List,

        I'm doing some benchmarking involving read a WAV file into my gnuradio 
program, executing a APT Decoder, and writing out the result to a file. I'm 
finding that my results are all I/O bound. I want to be able to load the entire 
file into memory (load the WAV file into a vector or other datatype) and then 
execute it, but still preserve the sampling rate. Is there a way of doing that?

What sample rate are you using that is causing issues processing a WAV file for APT? APT is relatively-speaking narrowband, so there's no way on gods little green earth that you'll be exceeding the read rate of your local disk for APT. If things are stalling, you're doing
  something wrong inside the flow-graph.
