I'm attempting to write a script, based on usrp_fft.py, that will read a file of gr_complex and display it. It works, except that it plays back much faster than it was recorded. For example, I recorded a five second file and gave it to my script. It looked to be correct data, but it finished playback in less than a second. Here's the essential code:
self.input = gr.file_source(gr.sizeof_gr_complex, options.filename, options.loop) adc_freq = 64e6 #inherent to USRP decim_rate = float(options.decim) #whatever decimation rate used in recording input_rate = adc_freq / decim_rate self.scope = fftsink.fft_sink_c(self, panel, fft_size=1024, sample_rate=input_rate) self.connect(self.input, self.scope) self._build_gui(vbox) ********************************************* Any help would be greatly appreciated.
