That's because you are using a useless subshell for a useless ls, and failing
to quote your variables. You need:
for f in *.wav; do
echo "$file"
done
ls is not responsible for doing filename expansion ("globbing"); the shell is,
so let the shell do it. Since you aren't using a subshell, word-splitting is
not done on its output.
The quotes are required to prevent the shell from performing word-splitting on
the contents of the variable; i.e. to prevent the filename "Track 2.wav" to
be sent to the echo command/built-in as two arguments: "Track" and "2.wav".
You wouldn't notice a difference in this case unless your filenames contained
tabs, newlines, or consecutive whitespace characters.
