I know that a source block of live IQ samples set to a certain sampling rate is equivalent to a File source of IQ samples followed by a Throttle block set to that same sampling rate. So far so good.
But suppose the system cannot keep up with a live IQ stream, or the equivalent File + Throttle and do all the desired signal processing. Is there another way to process a file of captured samples without a throttle block, yet produce equivalent results output to another file? Here is an example to illustrate the question: Live example: USRP -> AM Radio Demodulation, produces audio data -> Audio Sink Off-line example (3 separate flowgraphs, run one at a time): 1. USRP --> File 2. File --> AM Radio Demodulation, produces audio data --> File 3. File --> Throttle @ audio rate --> Audio Sink Note that #2 can take as long as needed to complete, no issues with loss of data. If so, how would I set up flowgraph #2 above?
