Hi:
I reading this page http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html#software. I am try to run example1 "Dial Tone Output", but I only listen to some voice. Why I can't creating a flow graph? Maybe I type wrong command? What is command should we type? I use gnuradio-3.1.1 on the windows(cygwin). Thanks. Example 1. Dial Tone Output #!/usr/bin/env python from gnuradio import gr from gnuradio import audio def build_graph (): sampling_freq = 48000 ampl = 0.1 fg = gr.flow_graph () src0 = gr.sig_source_f (sampling_freq, gr.GR_SIN_WAVE, 350, ampl) src1 = gr.sig_source_f (sampling_freq, gr.GR_SIN_WAVE, 440, ampl) dst = audio.sink (sampling_freq) fg.connect ((src0, 0), (dst, 0)) fg.connect ((src1, 0), (dst, 1)) return fg if __name__ == '__main__': fg = build_graph () fg.start () raw_input ('Press Enter to quit: ') fg.stop ()
