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.
Using the additive approach, UnWrap preserves the Left and Right channels bit transparent all the way down to the LSB of a 24 bit input. If the original stereo-mix is later requested, it can be obtained using only these two channels. If subsequent down-mix capability using all the channels is essential, this option is available too. In both cases, the LFE channel can be fully exploited, omitted or anything in between, as can the Center.
Bit Transparency When 0% L/R processing is selected, input trims and output levels are at 0dB, the inputs are bit transparently cloned to the L Front and R Front outputs. MAIN PAGE Input trims are provided to carefully match the L/R balance. If working from analog tape, adjust balance with a 1kHz calibration tone. If working from a digital master with stereo levels at full scale, it may be necessary to adjust down Input levels a little bit to avoid UnWrap overloads.
Now adjust the Decorrelation Tone and EQ parameters. Tuning of the surround parameters is an iterative process and should include the delay settings as well. D-MIX PAGE The downmix feature allows the user to check for stereo compatibility. Four fields are used to tell how much audio to extract from Left/Right, Center, LFE and sLeft/sRight surround channels. What is LtRt? An LTRT mix is usually used for a stereo optical, or for video. It is a two channel mix that decodes into four channels in your venue.
Global Plug-In Controls KEYBOARD COMMANDS The TDM versions of UNWRAP supports keyboard commands for certain functions. The following key commands are available for all plug-in parameters: Key Commands in Mac OS X: Fine Adjust = Apple key + mouse movement Reset To Default = Option + mouse click Key Commands in Windows: Fine Adjust = Ctrl + mouse movement Reset To Default = Alt + Control + mouse click AUTOMATION Please be aware that automation of certain parameters, can cause audible artifacts.
Main INPUT TRIM Left/right Input Trims Range: -12dB to 0dB Input level adjustment of the left/right channels. L/R PROCESSING L/R Processing Parameter range: 0 - 100% Determines the processing amount for the left and right front signals. LFE PROCESSING LFE Hi Cut Frequency Range: 10 to 200Hz Sets the Hi Cut frequency for the LFE channel. LFE Hi Cut Slope ENGLISH Range: Off, 2nd, 4th Sets the steepness of the LFE hi cut filter slope.
Center Contour Style Parameter range: Off and a selection of styles. Select between different styles as processing for the center channel output. Reference Level Parameter range: -25 to 0dB Set the Ref. Level control at the approximate reference level of the input signal. For a typical level, set Ref. Level at -10 to -18dB. With a full scale digital Input, Ref. Level would be set high, typically 0 to -12dB. With a quiet or highly dynamic input, set it between -15 and -25dB.
For Mid 1 and Mid 2 filters select between filter types: Parametric and Notch. Freq Press Freq and use Faders Range - Lo band Range - Mid1 band Range - Mid2 band Range - Hi band 1 to 4 to adjust frequency for each of the four bands. : 20Hz to 5kHz : 20Hz to 20kHz : 20Hz to 20kHz : 500Hz to 20kHz Gain Press Gain and use Faders 1 - 4 to adjust gain for each of the four EQ bands.
Surround Contour Style Parameter range: Off and a selection of styles. Select between different styles as processing for the surround channels output. Reference level Range: -25 to 0dB Set the Ref. Level control at the approximate reference level of the Input signal. For a typical level, set Ref. Level at -10 to -18dB. With a full scale digital Input, Ref. Level would be set high, typically 0 to -12dB. With a quiet or highly dynamic Input, set it between -15 and -25dB.
EQ The EQ for the Surround channel features four-band parametric EQ with high- and low-pass filters switchable between Notch, Parametric, Shelving and Cut filters. Basic operation • Select Freq, Gain or Type to access the same parameter for the four EQ bands. • Select Lo or Hi to access the three parameters for the individual EQ band. • Press Bypass EQ to bypass the entire EQ. Bypass does not affect the selected Contour Style. Type Selector • Press Type and use faders 1-4 to select filter types.
Range for the Parametric filter: Lo BW : 0.1oct to 4oct Mid1 BW : 0.1oct to 4oct Mid2 BW : 0.1oct to 4oct Hi BW : 0.1oct to 4oct Range for the Shelve filter: Lo BW : 3dB/oct to 12dB/oct Hi BW : 3dB/oct to 12dB/oct Range for the Cut filter: Lo BW : Bessel or Butterworth Hi BW : Bessel or Butterworth Delay OUTPUT DELAY Range: 0 - 200ms For each of the six outputs it is possible to adjust the delay time in milliseconds.
The total delay on an output channel is the normal ms delay setting, PLUS the sample delay setting. The actual time a delay set in samples varies depending on running sample rate. E.g. if you are running 48kHz, a 48 samples delay equals 1ms, and at 96kHz it equals 0.5ms. Also take system latency into account. Output OUTPUTS Mute Range: Muted/Unmuted Sets the mute-status on the output for each of the 6 channels.
D-MIX DOWNMIX LEVELS The downmix feature allows you to check the UnWrap settings for stereo compatibility. Downmix levels should match the settings for the external downmix device. Presets are per default set to the following values that match the ATSC A/52 standard: From From From From L/R C LSr/RSr LFE : : : : -3.0 dB -6.0 dB -6.0 dB Off dB It is important to check compatibility between: - the unprocessed original stereo signal by pressing the Bypass key - the signal unwrapped to 5.
Preset Management TC's comprehensive file based preset architecture makes archiving presets a simple process. This allows you to organize your presets the way you find most comfortable for your workflow, and to exchange presets with other users, no matter the platform or application. Presets are saved as discrete files on your hard drive. Once a preset is saved into the default location, it will automatically appear in the 'File' menu every time you use the plug-in.
DEFAULT PRESET LOCATIONS The following locations will describe where you can find the UnWrap presets.
The generated SysEx/MIDI preset file needs to be placed in the default UNWRAP Preset folder (at the root level; sub-folders are not considered). The file needs to have either the extension ".syx" (for example: MyPresets.syx) or .mid for a MIDI file. NOTE: In case you are running the Icon Editor on the same computer as the UNWRAP plug-in, the UNWRAP will automatically search for preset files in the default locations for and System 6000 files.
COMPARE SETTINGS WITH A/B MEM FUNCTION With the A/B compare function you can easily compare different parameter settings when you work with your music. You have two buttons: the "Mem" and the "A/B" button. When you start working with your preset, the A/B button is grayed out. This state indicates that the settings in both memory locations A and B are identical - so there is actually nothing to compare.
PARAMETER LOCK AT PRESET RECALL The parameter lock function allows you to lock the Dry Level, In Level and Out Level, from changing when you change preset. By using the parameter lock, you can easily browse through the extensive set of presets that comes with the UNWRAP, without having to change the Dry Level, In Level or Out Level all the time. To lock a parameter, simply click on the small lock in the parameter field. To unlock it, click again.
SETUP EXAMPLE This is an example of how to setup UnWrap on a stereo track in Pro Tools. 1. Go to: Setup - I/O 2. Add a set of 5.1 outputs. In the example below we have renamed the outputs to: “Surround Output”. Exit the menu. ENGLISH 3. Create a stereo audio track.
4. Click “Add” to the following common warning: 5. Now select the Surround Output that you created in step 2. 5. Select the “Surround Output” as the output of your track. ENGLISH That’s it.
