Hm well this works for me with the filename

$ ls *.wav
12 Missa brevis in G, KV 140App, C1. 12 Agnus Dei.wav

for i in *\ * ; do sox "$i" -r 44100 -t wav "output_$i" ; done

You need the -t otherwise sox gets confused trying to work it out from 
the suffix; because it contains dots in the file part it complains that 
the type " 12 Agnus Dei.wav" is unknown without -t.
