Fraunhofer IIS Wins Prestigious 2012 NAB Innovation Award

Dialogue Enhancement answers broadcasters’ challenge to deliver balanced dialog and ambient sound audio for TV and radio

LAS VEGAS – April 18, 2012 (Booth # SU6212) – Fraunhofer IIS, the world’s renowned source for audio and multimedia technologies, announces today that its Dialogue Enhancement technology has been selected by the National Association of Broadcasters (NAB) for its 2012 NAB Technology Innovation Award.

The Dialogue Enhancement technology is the first of its kind, allowing radio listeners and TV viewers to control audio volumes of dialogues and to tailor the sounds to their liking. Fraunhofer will be demonstrating this technology at its NAB booth, using clips from an experiment it conducted with the BBC during the 2011 Wimbledon lawn tennis tournament. The demonstration provides visitors with a first hand experience, allowing them to control the relative volume of commentary and court sounds.

The 2012 NAB Innovation Awards, open to all organizations exhibiting a non-commercialized service or product at this year’s show, was started in 2009 to recognize advanced technology exhibits and demonstrations of significant merit to the NAB Show.

“Dialogue Enhancement nicely complements our HE-AAC audio codec which is already widely used in broadcast and streaming,” said Harald Popp, head of the Multimedia Realtime Systems department at Fraunhofer IIS. “Whereas HE-AAC enables the efficient transmission of high-quality audio, Dialogue Enhancement dramatically increases the speech intelligibility which is one of the most demanded features by TV and radio audiences.”

Dialogue Enhancement and the Wimbledon experiment was shown as a technology preview at IBC 2011 in Amsterdam. TVB Europe selected it for the “Best of IBC2011” Editor’s Award in the category “Audio”, published in TVB Europe’s October issue.
