I can not get it to successfully output a wav file - issue at line 119

[bdorr1105]

The command I ran

sudo python /opt/spectrology/spectrology.py secret-text.bmp -b 16000 -t 25000 -p 120
Input file: secret-text.bmp.
Frequency range: 16000 - 25000.
Pixels per second: 120.
Sampling rate: 44100.
Rotate Image: no.

the error:

Traceback (most recent call last):
File "/opt/spectrology/spectrology.py", line 119, in

File "/opt/spectrology/spectrology.py", line 101, in convert

AttributeError: 'array.array' object has no attribute 'tostring'

Simply removing the .tostring() in line 102 will do the trick
