I want to use the *.ogg files available in Satnogs' database to test demodulation software for several satellites (using gnuradio).
Can i use the ogg file source (available in gr-satnogs module) and transform its output to complex data and then do the signal processing as if i were using raw IQ data comming from a SDR ? And in this case, what sample rate is suitable in the throttle block ?
Or, if not possible, should i convert the *.ogg file first to a *.raw file, using sox for example (Sound eXchange program) and then use it in gnuradio ? In this case, what are the parameters (input file sample rate, output file sample rate, encoding, sample size in bits, etc ...) i must use ?
