Can't you tell whether the wavs are stereo or not by listening to them? In a mixer program like aumix (curses), for example, channels which are "stereo-capable" (sic) will have balance controls (makes sense). So that might be a roundabout way (opening up the old mixer, don't you know) to reassure yourself concerning your mic (or bum yourself completely out after having converted the entire pianistic *oeuvre* of Chopin from vinyl to digital *mono*, depending). But if you are unable discern the difference by listening forget it and be happy. -- “Certitude is not the test of certainty.” --Oliver Wendell Holmes, Jr.
