Error: Too many indices for array

[Blobtoe]

I'm getting an error when running trying to decode noaa signals with this command:
main.py -c 137000000 -f 137100000 -d noaa "audio.wav"

I believe the error comes from line 623 in decode_noaa.py

Here is the output on the console:

INFO     Offset for this frequency was determined to be 100000.000000 Hz
