The Samsung T8 uses the DNSe (Digital Natural Sound Engine) sound technology. The technology was originally applied to the 5.1 audio system of the Samsung home theater system and is now being promoted to MP3 players. With the help of a portable audio system, it brings a more realistic feeling and strengthens the accent. It eliminates the common popping sound in ordinary products. The Samsung YP-T8 incorporates DNSe's extraordinary sound effects.
The two newly released MP3s, the Blue Devils V10 and iAudio U3, all use the TELCHIPS top-level chip TCC770 chip, and have audio technology such as SRS WOW, BBE, Mach3Bass, MP Enhance, and 3D Surround.
In addition, the distinction between USB2.0 interface also allows us to learn a lot of knowledge. Now MP3 USB1.1 interface has become less and less, basically are 2.0 interfaces, but the market is divided into USB2.0 USB interface full speed 2. .0 (USB2.0F) and high-speed USB2.0 (USB2.0H), the performance of the two varies greatly. Full-speed USB2.0 (12Mbps) does not have much speed boost compared to USB1.1, while high-speed USB2.0 (480Mbps) Is the standard. We can understand the decoder chip to distinguish between high-speed and full-speed USB2.0 interface, such as Philips PNX0102 chip, SigmaTel 3520, TeleChips TCC76X series chip supports USB2.0 high-speed interface, on the contrary, the corresponding Philips PNX0101, SigmaTel 350X series The chip, TeleChips TCC72X series chip can only be full-speed USB2.0 interface.
