-Transmit N simultaneous narrow band FM signals.
-
-They will be centered at the frequency specified on the command line,
-and will spaced at 25kHz steps from there.
-
-The program opens N files with names audio-N.dat where N is in [0,7].
-These files should contain floating point audio samples in the range [-1,1]
-sampled at 32kS/sec. You can create files like this using
-audio_to_file.py
