UNWRAP BACKGROUND
From kitchen to cinema
Today's music has to be purposed for a number of different reproduction situations,
from a mono kitchen radio over a CD stereo system to a full size cinema.
Because no true down-mix or up-convert standard exist, control over this important
process can only be achieved by handling it at the mastering or mix studio; thus
producing one type of master for every major target reproduction situation.
Re-mixing for multichannel
If the source tapes are still at disposal and the budget is available, the only way to
take full advantage of the original material is by performing a re-mix. In a best case
scenario you will end up with different mixes each exposing full potential for the
format for which it was tailored.
Re-mixing can be an expensive and time-consuming process, but with experienced
engineers, the method should be chosen to fully exploit the possibilities of 5.1 and
beyond.
Up-conversion
Many reasons can exist for seeking a high quality up-conversion alternative to a re-
mix, if...
• multitrack tapes never existed
• original source tapes are not in a suitable condition
• budget considerations prevents you from re-mixing
• a stereo soundtrack needs replaying using all the cinema channels
Finally there could be a more controversial reason with classic tracks: Maybe we don't
really want Strawberry Fields or The Boxer submitted to new balancing and Y2k
effects.
UnWrap
For situations where up-conversion is indicated, TC now offers its renowned
production quality processor, UnWrap. Using a brute force DSP approach, UnWrap
preserves the qualities and resolution of the original mix way more than mediocre
processors found in current hi-fi equipment.
UnWrap is a double precision algorithm capable of running at any sample rate
between 44.1 and 96 kHz. Applications typically include mastering, film production
and broadcast conditioning.
Because up-conversion is not a one-size-fits-all process, UnWrap offers a palette of
options to be used for different types of program material, thereby giving as much
creative freedom as possible to the engineer performing this important task.
Basic conversion options
Some conversion options are of a profound nature, e.g. if the process is thought of as
purely additive, if the ability to collapse to stereo again is important, or if an LFE
channel should be derived or not.
