Users questions: Who used this USB external sound card do? How the effectiveness and quality like?
Experts answer: seen this stuff, but never used. But to help you find the relevant description, can learn about: USB sound card, advantages and disadvantages of the soft sound card style USB sound card, although the principle and structure, and common on-board sound card is class Similar, but the external features make it far with the latter, advantages, and because there is no external restrictions on the circuit size, it makes it possible to design more complex analog circuits and using better shielding design, which dramatically enhance the sound quality, even as the "flash card" the same without any additional Strong design, from the internal chassis environment of high electromagnetic interference and the use of USB in the independent power supply, which in itself enhance the sound quality for the sound card is great. So, as long as not too bad design, USB sound card should be compared with the same chip and the design community structure of the built-in sound card better sound performance. In fact, It had completed the CNR for the sound card did not want something made. However, USB sound card also has its serious shortage can not be ignored. This shortage comes from the USB bus itself. USB bus, is a slow and low-level bus system. Old due to the speed of USB1.1 sound card Constraints, so they can not transmit more data, which makes innovative Although the first generation of USB sound card as much as the main chip powerful AUDIGY, but the USB speed limit by less than the actual performance achieved as a Live!. Most modern USB sound card to use the USB2.0 interface, speed Degree of the problem is solved, but another problem is difficult to solve - USB bus-priority PCI bus is much less, making the state the system is busy, USB bus is often not enough CPU time, for most USB equipment that is no problem, but the demand for real-time data USB sound card is great, there will be intermittent phenomenon. Moreover, users of the USB device is also a problem, because USB bus using shared mode, so USB drives, USB drives which also require large data flow of the device and the USB sound card will compete for limited data with Wide, resulting in USB sound card and share these devices will appear as the year when PCI sound card and PCI cards are the phenomenon of sonic boom occurs. So, when using these devices, be sure not to them, and USB sound card with a USB interface, while (in fact, strictly speaking, a USB control Device) on. All in all, USB sound card with built-in sound card, especially on-board AC'97 soft sound card compared to the greatest advantage is the ability to get better sound quality output, but by the USB bus inherent limitations, even more than the onboard sound card for gaming software resources like CPU and bandwidth on demand urgent Application.
