Discussion Of Results
This card has an unusual, slightly disturbing, but possibly useful combination of near-telephone quality in record mode (Analog -> Digital) and near-CD quality in playback mode (Digital -> Analog). This means that is may perform acceptably in most game, music playback, web telephone, and other consumer applications, but would be unacceptable for for semi-pro or professional sound recording and editing applications, of any kind.
