Hi,
actually what I was trying to do carries from my last post, where my
media files are a list that I want to add to the
subprocess.call(['sox', ', '.join(media_list), 'list.wav'])
>>> print ', '.join(media_list)
upper_b.wav, upper_a.wav
>>> subprocess.call(['sox', ', '.join(media_list), 'list.wav'])
sox formats: can't open input file `upper_b.wav, upper_a.wav': No such
file or directory
2
>>>
but this is treated as one item, rather than the two.
