Nor can I very well. After some googling, I see that apparently this would be called "auditory affective agnosia" (if it were at the level of neuropsychological pathology). I wonder if this software could be used diagnostically in disorders that are associated with deficits in empathy or emotional identification -- autism, Antisocial or Narcissistic Personality Disorders, etc.

Perhaps it could also be used as a therapeutic tool. One could train with it in order to reduce the affective threshold at which one detects emotion.
