RATE/CHUNK is an integer, but TIME when extracted from sys.argv is a str. 
The * operator tells python to repeat the string RATE/CHUNK times:

>>> RATE = 44100
>>> CHUNK = 1024
>>> TIME = "2"
>>> RATE/CHUNK * TIME
'2222222222222222222222222222222222222222222'

You need to convert TIME to an int before evaluating the expression to get 
the expected result:

>>> RATE/CHUNK * int(TIME)
