T16 - The Evolution of Stereo to Surround Sound—What Do the Various Present Day Formats Really Bring to the Surround Sound Experience
Presenter:Michael Williams, Sounds of Scotland - Le Perreux sur Marne, France
Abstract:
This presentation will explain the configuration of the different formats, their faults, and the possible improvements that are possible. This presentation will also allow the listener to compare different formats - stereo with triphony, quadriphony with multichannel, multichannel with Blue ray, quadriphony with Blue ray, etc. This comparison process is the result of simultaneous multiformat recordings and uses fast cross-fading between the different formats. This fast fade technique is used in order to improve perception of the advantages and faults of different format configurations. This presentation will use a basic eight channel horizontal loudspeaker configuration which is the basic Blue ray loudspeaker configuration plus a back channel. This experience has already been presented to the French Section of the AES in a meeting in Lyon. As the comparison point of each format is produced, a unique method of synchronization of powerpoint slides will inform the listener of the structure of each individual reproduction format.
