Hello:
I am working in GRC making an AM Modulator. I’m trying to use the Wav
File Source block and I tested with an Audio Sink block, but this is the
error that I get:
Traceback (most recent call last):
File “/home/cafequilar/FlowGraphsGRC/usrp_am_transmisor.py”, line 82,
in
tb = usrp_am_transmisor()
File “/home/cafequilar/FlowGraphsGRC/usrp_am_transmisor.py”, line 57,
in init
self.gr_wavfile_source_0 =
gr.wavfile_source("/home/cafequilar/FlowGraphsGRC/popeeye.wav", True)
File
“/usr/lib/python2.7/dist-packages/gnuradio/gr/gnuradio_core_io.py”, line
1782, in wavfile_source
return _gnuradio_core_io.wavfile_source(*args, **kwargs)
RuntimeError: is not a valid wav file
I’ve tried using 3 different wav files but is always this error. Please,
any suggestion would be well received.
Thanks!
