Answer 1

do this:

m = [['qw','wew','23','C:/xyz/s.wav'],['qw','wew','23','C:/xyz/s2.wav'],['qw','wew','23','C:/xyz/s1.wav']]
fname = m[0][3]
print 'fname is', repr(fname)
win = wave.open(fname, 'rb')

and show us (using copy/paste into an edit of your question) everything that is printed, especially
(1) the result of print 'fname is', repr(fname)
(2) the ERROR MESSAGE
