I normally record on Audacity, then export as a WAV to WP. There are no options listed other than just to export.
Then I edit in WP and when I "save as" I get a menu of "attributes" listing saving as PCM, and choices of 8000 bit all the way to 48000 bit, mono or stereo. I am interested in maximum quality. but wonder what "attributes" came with the export to WP and whether the choices listed above make any difference after I have finished editing.
