Chair: Bob Zurek (Send E-mail) Vice Chair: Andrew Bright (Send E-mail) The mission of the Technical Committee on Audio for Telecommunications is to deal with audio quality issues as they arise in the field of telecommunications. The intent of the committee is to provide guidelines for the design and integration of the audio components of telecommunications systems, to advise industry standard organizations on the audio issues presented by new technologies and telecommunication formats, and to disseminate information regarding telecommunication audio issues to the membership as applicable. It is the goal of the committee to ensure that audio quality and intelligibility are retained as devices decrease in size and new formats are created. The committee will concern itself with both the infrastructure and consumer ends of telecommunications systems as they affect the total system's sound quality.
