If you’re interested in PC audio, once you think about it, “Why does the sound change even though it’s digital?<\/p>\n

It is unlikely that the data cannot be corrected and returned to the original data with current digital audio equipment, so the digital data itself is safe to think that they are the same. Then why?
\nThe reason is that even though it is digital, the signal that drives the speaker is an “analog signal”, so it affects the “analog signal” after the digital is converted to analog.
\nSuppose you have a noisy PC. As shown in the figure below, noise flows through the GND of the USB cable to the USB-DAC. The noise flowing into the USB-DAC affects the signal after analog conversion and the sound quality deteriorates.<\/p>\n
On the other hand, a PC with less noise has less effect, so the sound quality is less likely to deteriorate.<\/p>\n
In the case of “wireless” at the end, “wireless” is the “ultimate USB cable”. It is not affected at all by PC noise. It is an ideal transmission method. The only embodiment of such a method is “Air High Resolution Link Technology”.<\/p>\n","protected":false},"excerpt":{"rendered":"
