PathFromScheme is a helper function that we can use when developing 
modules in c++.

strings and paths are also supported. it works like the racket path 
functions, they accept paths and strings also.

i'm not really familiar with the audio functions, but it's quite 
straightforward to change any functions from strings to paths.
