DNSe or the Digital Natural Sound engine is a DSP audio enhancement technology developed by Samsung in 2003 and further on implemented throughout many of their product lineups - from TVs and DVD players to portable music players and lately - mobile phones.
As Samsung puts it, the aim of DNSe is to restore the best sonic experience to the end user. Purportedly, the sound engine yields higher quality sound with more natural effects than conventional methods by reproducing the 'genuine' stereo sound intended by the music content creators. It achieves this by actively working on overcoming the limitations of earphones and less-than-ideal speakers to offer realistic stereo and deep bass sounds.
In addition, Samsung have created ideal listening presets that further compensate for the native restrictions of portable multimedia players. The system uses several basic processing methods aiming at various imperfections of the sound produced by portable players.
Concert Hall recreates life-like reflected and reverberated sounds to simulate the experience of a live performance in a concert hall. 3D speaker separates and combines sound to create realistic sense of both space and distance through small-sized speakers. Clarity enhancement tries to electronically restore the distorted harmonics of the digitally compressed music. Bass Extension applies an electronic harmony logic to correctly play hi-fidelity sounds at an ultra-low frequency through earphones or small-sized speakers. And finally, Street mode selectively adjusts volume so that the tiny notes are audible even in the loud street environment without the uncomfortable boosting of the general volume level.
The DNSe sound enhancement system combines those sound enhancements with different equalizer settings to create various user-centric presets to suit the most common listening scenarios. If that is not enough, the system alows creating custom presets as well.
Samsung DNSe is not to be confused with the Samsung proprietary DNIe (Digital Natural Image engine) technology. DNIe is used in Samsung plasma and high definition television sets (HDTV). Purportedly, DNIe offers better detail than conventional televisions by using four proprietary processes that optimize and enhance image quality: a Motion Optimizer, a Contrast Enhancer, a Detail Enhancer, and a Color Optimizer.
