The WAV les created with subsequent 3D sound rendering can be mixed later in an external sound
program for the generation of surround sound data in the DTS 5.1 format. You can dene individual
values for the pickup characteristic etc. of all microphones (see ‘Mono Microphone’ earlier in this
chapter).
DDS EX 6.1
DDS EX 6.1 is a modern method from Lucaslm TXH and Dolby Laboratories Inc.
It uses an additional middle surround channel to offer the listener a particularly
good localization of auditory perspectives. Otherwise it is compatible with
Dolby digital 5.1. The number ‘6’ from the name refers to the six available
channels. The front three (left, center, right) use the frequency range from
20Hz to 20kHz and the three surround channels the range from 80Hz to 20kHz.
The rear channel is the sub-woofer, which uses only low frequencies in the
range between 20Hz and 120Hz.
This ‘surround sound’ microphone is not an object in the conventional sense,
but a predened group of objects containing several mono microphones.
The DDS EX 6.1 (Dolby Digital Surround) function creates, automatically, a group of objects which
contains seven conventional, spatially-shifted mono microphones.
