UnWrap HD puts the process of converting from stereo to 5.1 in the hands of an audio professional. It is the world's primary high-resolution up-conversion processor, and with its wealth of controls, UnWrap HD is the de facto standard in film, post and music production. Thanks to rigorous phase and resolution preservation in the algorithm, up-converted material may even be subsequently down-mixed to stereo again with no sonic penalties. Processing is 48 bit, and sample rates up to 96kHz may be used.
Unwrap HD is no one-size-fits-all solution, but provides a host of parameters to aid the design of a result faithful to the original with regards to width, timbre, spaciousness, foreground/background discrimination, and other important factors. Users upgrading from UnWrap to UnWrap HD will experience even more such tweakability. Still, there may be situations where up-conversion won't provide a satisfactory result, and where the recommendation w ould be "perform a new mix or forget it".
The UnWrap HD license includes up-conversion presets for stereo and LtRt program material typically dealt with in broadcast, film production and music mastering. Take a preset tour to spark your creativity, or start a new up-mix from scratch. Presets are located in Factory Bank F11, decade 3-5. Presets generated with the original UnWrap application may be read using UnWrap HD, and still sound precisely like when they were created.
