Next Generation Audio codecs are gaining traction in consumer devices. Their capacity for audio personalisation has considerable potential for enhancing dialogue understanding. However, the degree of control and type of user-interface desired by audiences in realistic viewing scenarios remains unexplored.
This paper investigates the preferences of normal hearing audiences (n=18) who were presented with interfaces ranging from ‘on/off’ to a graduated slider across three content types in a typical viewing environment. Preferred settings and rankings of the controls were collected along with qualitative feedback. Preferences varied dramatically across both genres and participants, evidencing the need for delivery of object-based audio assets to facilitate the desired variety of personalisation control. Future work with a hard of hearing cohort is also discussed.
