Controlling Echo in the Musical Videoconference

Time 09/28/04 03:00PM-04:00PM

Session Abstract

Research indicates that high-quality audio is key to any successful videoconference experience, and in the musical videoconference, it is of the utmost importance. One of the main obstacles to high audio quality continues to be echo. Although a number of echo-cancellation devices exist, the algorithm by which they work drastically reduces the audio quality of the videoconference to the point that trained musicians deem it unacceptable. This session will focus on a number of strategies using common recording studio techniques and off-the-shelf equipment to control echo while still maintaining a high-quality audio signal. Concepts will include microphone selection and placement, physical echo cancellation and the use of electronic devices to minimize echo and its impact on the videoconference participants. Session attendees from multiple disciplines will benefit from the opportunity to see these techniques in action, as the presentation will include a remote connection to the New World Symphony's facilities in Miami, Florida. This remote connection will allow us to demonstrate the before-and-after effect each of the techniques has
on controlling echo.
