DNSe 2.0 : Music That Comes Alive

Samsung Electronics Co., Ltd. is one of the fastest growing global brands, and aproven leader in semiconductor, telecommunication, digital media and digital co

nvergence technologies. Over the years, Samsung has built and reaffirmed its rep

utation for improving customers’ lives with groundbreaking technological advancements.

In 2003, Samsung first launched its new sound enhancing technology, Digital Natural Sound engine (DNSe), after years of research on audio DSP and acoustics. Since then, Samsung has continued to fine-tune this technology, investing in R&D onDNSe, to provide the ultimate in sound fidelity on Samsung products ranging fro

m TVs, DVD players, stereo systems, and MP3 players.

The aim of DNSe 2.0 is to restore the best sonic experience to the end user. Thenew sound engine yields higher quality sound with more natural effects than con

ventional methods by reproducing the “genuine” stereo sound intended by the music co

ntent creators. It achieves this by overcoming the limitations from earphones and less-than-ideal speakers to offer realistic stereo and deep bass sounds.

In addition, Samsung has sculpted ideal listening experiences that further compensate for the native restrictions of portable music and multimedia players. Using embedded technologies that include 3D, Street Mode, Clarity, and Concert Hall,Samsung has tweaked these functions into user-centric presets, ranging from Roc

k to Classic, Vocal to Bass Boost, that further heighten the music experience.

With any DNSe-enabled device, you can go on an aural journey…from the Met where symphony orchestras come alive to the hottest underground club where bass-enhancedmusic gets you dancing. Whichever type of music you listen to, Samsung’s DNSe tec

hnology will ensure that it comes alive in your ears.

Samsung’s DNSe 2.0 technology has already been implemented, through a firmware upgrade, in the YP-K3 MP3 player, which was released early in 2007. DNSe 2.0, as well as future upgraded versions of the sound engine technology, will be incorporated in all of Samsung’s new MP3 players. More information on these devices will beavailable at a later date.

< Natural Stereo Sound >

Stereo sound is important to music lovers because it translates what would otherwise be a flat and unnatural sound to music that sounds as if it is being playedlive in your ears. However, by nature of the physical limitations of earphones,it is generally difficult to achieve a satisfying stereo listening experience b

ecause of the unnatural channel separation to the left and right earbuds. Even stereo speakers on portable devices pose an acoustic dilemma because they are tooclose together to simulate an ideal stereo environment.

Achieving a genuine 3D stereo sound image requires the exact positioning of theleft and right speakers as well as the listener in order to achieve the perfectbalance of sound going to left and right. This means having some of the left cha

nnel being heard in the right ear, and a portion of the right channel being audible in the left ear.

Samsung’s DNSe 2.0 successfully achieves this optimal balance through proper signal processing, enabling portable music devices with earphones or speakers to recreate the ideal stereo image intended by music creators. Audiophiles can now enjoy the same acoustic fidelity on the go that they would achieve with their engineered home stereo system.

< Deep Bass Resonance >

The physical limitations of earphones or small speakers also limit the reproduction of a thick, full and meaty bass sound; often, only bass and upper bass registers are audible. Depending on the type of music you listen to and what the original intent of the music creators are, this could lead to a less-than-satisfyinglistening experience. For instance, the low bass sounds in hip hop or dance mus

ic provide the base for the music; the bass line is the groove of the song thatpeople dance to. Without the deep bass sounds, the music would lose a dimensionin its audible experience.

To correct these limitations, DNSe uses a psycho-acoustic phenomenon called Missing Fundamental that allows users to hear the lowest registers of rich bass sounds, even when it is physically impossible to do so. Nearly all sounds consist ofa combination of several frequencies, the lowest of which, the fundamental freq

uency, is often too low to be produced on portable music devices. DNSe calibrates the other frequencies in a way that enables the ear to believe it is hearing deep bass sounds. The processed bass overtones compel the brain to replace the missing fundamental bass signals, creating the illusion of the low bass registers.In doing so, DNSe enables portable music devices with earphones or small speake

rs to simulate the acoustic depth that could only be achieved with more sophisticated equipment.

< Design Your Acoustic Experience >

DNSe incorporates embedded technologies that tweak the sound in order to optimize the desired sound image. Using different formulations of technologies, Samsunghas created numerous preset settings that enable you to easily customize your l

istening experience according to genre of music or other desired acoustic circumstances.

This audio post processing that takes place enables the music players to restorethe best sonic experience for the listeners. By reproducing the genuine stereo

sound intended by the music contents creators, audio enthusiasts can rest assured that they can listen to optimized acoustics that enhance the type of music they are listening to.

The preset EQs breathe life into the portable music player. They tweak the musicso that classical music paints sweeping vistas of sound…as if you are in a concer

t hall. So that hip hop music blares pulse-pounding bass…as if you’re dancing in thehottest club. Users will be able to conveniently select the preset that makes t

heir music come alive, taking full advantage of all DNSe 2.0 has to offer, and enjoying music as it was meant to be heard.
