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 DDS EX 6.1 format. You can dene individual
values for the pickup characteristic etc. of all microphones (see ‘Mono Microphone’ earlier in this
chapter).
SDDS 7.1
SDDS 7.1 works, in principle, like Dolby Digital 5.1. Additionally, however, the
number of center channels is increased from 1 to 3. This makes a better sound
distribution possible with the large and broad projection screens in cinemas.
Otherwise it is compatible with Dolby Digital and DTS. The number ‘7’ in the
name refers to the seven available channels. The front ve (left, left center,
center, right center, right) use the frequency range from 20Hz to 20kHz and
the two 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 SDDS 7.1 (Sony Dynamic Digital Sound) command creates a group of objects which contains eight
conventional, spatially-shifted mono microphones.
