Total Surround Sound (TSS) System with Floor Loudspeakers Author: Tomislav Stanojevid, B.Sc.E.E.
TSS 3D audio system is applicable in the following ambients: • Digital Cinemas • Live Theaters • Multimedia Halls • Presentation Rooms • Video Game Halls • Home Theaters • Club Discotheques Floor loudspeakers are essential for generating full 3D surround sound Basic idea has been published a few years before introduction of Kodak CDS, Dolby Digital, Dolby Digital Surround Ex, Dolby Atmos and Barco’s Auro 11.1 formats Concept and construction of floor loudspeakers has been protected as Patent No. 1332U, 2013 (www.espacenet.com)
Basic Concept • TSS System is full 3D audio system with special disposition of loudspeakers in the cinema, multifunctional or multimedia halls etc. • TSS concept for the first time was presented on the AES Convention in Hamburg, 1989, when yet there was no digital cinema multichannel audio - only analog format as Dolby Surround (later SR) with single mono surround channel • TSS System was first cinema audio system which is migrated from mono surround into a multichannel surround system with wall, ceiling matrix and floor sound sources • A few years after TSS System introduction in 1989, Lucas film and Dolby Labs added to Dolby Digital format new channnel, named Surround Ex, for loudspeakers on the rear wall
System versions of TSS concept (1989) (1990) (1995) (1991)
Similarities between Barco Auro 11.1 and TSS concept Auro 11.1 (2011) (1995) (1989)
Similarities between Dolby Atmos and TSS concept (1989) (1991) Dolby Atmos (2012)
Channel based versus object-based sound in 3D Up until recently, all these sound elements were distributed over several audio ʻtracksʼ and mixed in a reference studio using huge mixing consoles and digital audio workstations compliant with a standardized speaker setup. The end result of this process is a set of ʻchannelsʼ, each channel representing the content of one speaker or speaker-array (for the Surround channels). This is called the ʻChannel - basedʼ approach and is in use by virtually all production facilities throughout the world. In an ʻObject - basedʼ system, the different sound elements are bundled with metadata to form audio objects. This metadata then describes how the sound element should be reproduced in the theater, by defining its position in the 3D-field with a vector, level, etc … The playback system then needs to render that information in real-time for each object related to the playback systemʼs speaker layout. As such, Object-based systems always need special, dedicated hardware (rendering-stations), depending on the system of choice.
Additional Cinema 3D Audio Formats Surround 10.2 is developed by Tomlinson Holman (Ex THX). System is consiting of 5 front and 5 surround channels. 22.2 Channel Surround developed by NHK Science & Technical Research Laboratories is consisting of 3 loudspeakers layers: • Middle with 10 loudspeakers • Higher with 9 loudspeakers • Lower with 3 loudspeakers and 2 SW sections

Floor loudspeakers – next step New solution for floor loudspeakers will be very flexible and very convenient for installation. This solution may be used with special 3D digital audio processor, and corresponding software.
