Making dialogs accessible for everyone: “Listening Effort Meter” helps in post-productions to avoid poor speech intelligibility

Exhibitor
Fraunhofer Institut für Digitale Medientechnologie IDMT Institutsteil HSA

The “Listening Effort Meter” (LE-Meter) developed by Fraunhofer IDMT in Oldenburg, Germany, allows sound engineers to visualize listening effort during mixing and conduct post-mixing checks to optimize audio quality. Dedicated algorithms provide recommendations for action based on an objective analysis of listening effort in real time.

The technology has already found its way from scientific development into commercial application, for example integrated into RTW’s TMxCore measuring device and NUGEN Audio’s plug-in DialogCheck, and is intended to bring about improvements in media production on a broad scale.
