LS既然知道是异步,能否说下如何知道是同步异步?

Low Clock Jitter with Asynchronous Data Transfer

Most USB audio uses Synchronous Data Transfer mode to adjust the internal clock to compensate different data transfer rates between PCs and USB audio devices. But the jitter is worse if the transfer rate is different between a PC and the audio device. To avoid this issue, the ASUS Xonar Essence One supports Asynchronous Data Transfer mode. This mechanism feedbacks the buffer status to the system, and the system is based on buffer status to adjust to the speed of the data transfer, which leads to a low amount of jitter in the Xonar Essence One. |
