-"""Convert "arbitrary" sound files to AIFF (Apple and SGI's audio format).

-Input may be compressed.
-Uncompressed file type may be AIFF, WAV, VOC, 8SVX, NeXT/Sun, and others.
-An exception is raised if the file is not of a recognized type.
-Returned filename is either the input filename or a temporary filename;
-in the latter case the caller must ensure that it is removed.
-Other temporary files used are removed by the function.
