1. Program related conversion options It has been TC s goal to provide presets that can make any kind of program material present itself better and more engaging in 5 1 than in stereo From old to recent pop and rock music from unique classical recordings to highly ambient modern tracks from ultra dry to wet source material UnWrap comes with settings to complement it all Add to the default presets the capability to time align all channels at sample precision widen or narrow the image control the amount of Center and LFE channel to be used change filters and envelopes and you begin to get an idea of the power behind this new algorithm Introduction UnWrap in use UnWrap measures phase delay and spectral differences between a pair of stereo channels to create a 5 1 result For different program material there will be different optimum settings that best represent the qualities put into the original mix Please familiarize yourself with the controls and parameter ranges on known material before you attempt unwrapping new stuff Setting up Try loading some of the UnWrap presets You can A B the process by pressing Bypass You may also experiment for stereo compatibility using the downmix levels on the D MIX page Time alignment When all Delays are set at all Outputs from UnWrap are aligned with sample precision The basic Delay through the algorithm in this case is 3 6 ms at 44 1 and 48kHz Try offsetting the Delays in sampl2. 02oct to loct 1 BW 0 020oct to loct Mid2 BW 0 02oct to loct Hi BW 0 020oct to loct Range for the Parametric filter Lo BW O loct to 4oct 1 BW O loct to 4oct Mid2 BW O loct to 4oct Hi BW O loct 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 UNWRAP TDM 9 Surround t c electronic 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 OdB 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 to 12dB With a quiet or highly dynamic Input set it between 15 and 25dB Decorrelate Style Range A selection of styles The decorrelating styles are highly subjective and best evaluated with the Focus control set at When a style is found try changing the Focus control to check if further optimization is possible It may prove convenient to solo the surround channels while doing so Focus Range 0 100 Set how much you want to decorrelate the sound in the surround outputs Decorrelate Tone Range 40 steps Adjust the tone color of the decorrelated part of the sound on the su
