NAB Preview: DTS Plays Key Role in DaySequerra’s Mono2Stereo Synthesizer

DaySequerra’s new four-channel Mono2Stereo synthesizer uses DTS Neural Technology’s proprietary algorithm developed to produce an artifact-free, wide soundstage with perfect, spectrally balanced stereo from mono content. The Mono2Stereo’s DSP-based algorithm provides a pleasing stereo soundstage with a smooth, seamless transition from mono to stereo.

Mono content is synthesized into stereo with width and depth information creating a convincing image often indistinguishable from original stereo content. Easily accessed user presets store settings of the Mono2Stereo’s four channel-dedicated “stereo-width” controls, crossover frequency, high- and low-shelf filters, and audio limiter that can be recalled at the touch of a button. This streamlines setup time, allowing plug-and-play use once desired settings are achieved for specific projects. Not only does the Mono2Stereo deliver high-quality audio performance, but the four-channel capability allows mixers more control of mono content on the fly, for a better stereo and 5.1 mix overall. Priced at $6,000, it is available now.

The DaySequerra NLC5.1ST measures and maintains desired audio loudness levels simultaneously for 5.1 surround and stereo programs in a single-rack-space unit. It measures and controls perceived loudness of the program audio using the industry-standard ITU-R BS.1770/1 and DTS Neural Loudness Measure (NLM) algorithms. The NLC5.1ST then uses the proprietary DTS Neural Loudness Control, an advanced loudness-leveling algorithm, to apply the appropriate gain or attenuation to maintain the broadcaster-defined loudness level. The resulting audio has a naturally open, dynamic quality without the annoying side-effects of traditional energy-based volume management. The NLC5.1ST will be available in April priced at $12,000.

The DaySequerra MultiMerge2 provides 5.1 surround sound for HDTV viewers as well as stereo sound for SDTV transmission, whether the original content is stereo or discrete 5.1 surround. MultiMerge2 provides a seamless transition between 5.1 and stereo content. Original 5.1 is passed through unaffected while stereo is rendered to surround via the DTS Neural Surround process. Using the DTS Neural Surround DownMix process, MultiMerge2 also provides full-time stereo output. The MultiMerge2 outperforms all existing upmixing methods for channel discreteness, envelopment, and original spatial location. It will be available in April priced at $12,000.
