Dialogue Enhancements-technology and experiments

Finding the right balance between dialogue and ambient sound is a major challenge for sound engineers, and an increasingly common cause of audience complaints. It may therefore be desirable for audiences to influence the audio balance to suit their personal choice, their listening environment and their hearing. A new “Dialogue Enhancement” technology from Fraunhofer IIS addresses this challenge. It is backwards-compatible and adds only a moderate bitrate overhead to the transport bitstream, and is thus well suited to broadcast applications.
