Natural sound stereo
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 played live in your ears. However, by nature of the physical limitations of earphones, it is generally difficult to achieve a satisfying stereo listening experience because of the unnatural channel separation to the left and right earbuds. Even stereo speakers on portable devices pose an acoustic dilemma because they are too close together to simulate an ideal stereo environment.

Achieving a genuine 3D stereo sound image requires the exact positioning of the left and right speakers as well as the listener in order to achieve the perfect balance of sound going to left and right. This means having some of the left channel 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-satisfying listening experience. For instance, the low bass sounds in hip hop or dance music provide the base for the music; the bass line is the groove of the song that people dance to. Without the deep bass sounds, the music would lose a dimension in 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 of a combination of several frequencies, the lowest of which, the fundamental frequency, 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 speakers 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, Samsung has created numerous preset settings that enable you to easily customize your listening experience according to genre of music or other desired acoustic circumstances.

This audio post processing that takes place enables the music players to restore the 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 music so that classical music paints sweeping vistas of sound...as if you are in a concert hall. So that hip hop music blares pulse-pounding bass...as if you're dancing in the hottest club. Users will be able to conveniently select the preset that makes their music come alive, taking full advantage of all DNSe 2.0 has to offer, and enjoying music as it was meant to be heard.
