 ITU-T workshop on "From Speech to Audio: bandwidth extension, binaural perception"
 Lannion, France, 10 – 12 September 2008 Contact: 
For several decades, digital voice communications have used narrow band speech codecs. In that time teleconferencing and videoconferencing applications have seen increased popularity.

This workshop will present the status of existing and future developments of wideband, superwideband and fullband codecs as well as relevant applications from speech to mixed content and from advertisement to music on hold and even to film trailers. Moreover the potential advantages from the use of spatialisation, multichannel transmission and 3D sounds will also be explored.
The goals of the workshop are:
  • to provide inputs to develop new methodologies covering the complete audio bandwidth from Narrow Band to Fullband and continuing to ensure compatibility with existing ITU-T Recommendations.
  • to review terminal characteristics to cope with new bandwidth requirements and multichannel aspects in function of the evolution of the codecs, transmission techniques and core/access networks (all IP, NGN, mobile).
The workshop aims to establish a constructive dialogue between universities, standardization bodies and companies to combine efforts and skills to create standards bringing interested parties together from around the world to promote innovation.
