Does anyone say “I really don’t understand” or “I can’t hear you anymore” over the audio? This is a super introductory course on audio that started in response to so many unexpected voices, and this time I will explain very briefly about the “PC audio” that I often hear recently.<\/p>\n

\n\u25cf First of all, what is “PC audio”?<\/p>\n
This time, let’s introduce PC audio.<\/p>\n
Until a while ago, the only way to listen to music was with a CD, MD or radio player.<\/p>\n
However, before I knew it, listening styles with digital music players, such as personal computers and iPods, became common.<\/p>\n
And the idea of \u200b\u200bPC audio is “I want to listen to music with good sound when I listen to music using a personal computer.”<\/p>\n
\u25cf The point is “DAC” which performs the digital to analog conversion.<\/p>\n
For example, when you listen to music on your computer, you usually listen to it like this.<\/p>\n

Connect headphones, etc. to the audio output terminal (LINE OUT) of your computer.<\/p>\n
Or you can play it through your computer speakers.<\/p>\n
So how do you make this sound good?<\/p>\n
When playing music with digital data, the DAC (duck) circuit is important in terms of sound quality.<\/p>\n
Since MP3 or WAV is digital data, but scanning for speakers or headphones to play, you need to convert the digital data to analog signal.<\/p>\n
DAC (short for D \/ A converter) performs the “digital-to-analog conversion”.<\/p>\n
The quality of the converted analog signal depends on the accuracy of the DAC.<\/p>\n
In other words, if the DAC is not good, it will not sound good at all.<\/p>\n
Originally the digital data is a list of numbers like “0101001 …”, but the figure is as follows. (* Image)<\/p>\n

If you are using your computer’s audio output terminal, you are using the DAC circuit inside your computer as shown in the figure below.<\/p>\n
However, since the personal computer was not originally made for music playback,<\/p>\n
The performance of the DAC installed in the personal computer is often not that high due to the balance of costs with other parts.<\/p>\n
Also, many electronic parts run at high speed inside the personal computer, so a lot of noise is generated.<\/p>\n
In such an environment, you cannot expect “good sound” in the audio sense.<\/p>\n

\nTherefore, instead of using the DAC inside the personal computer, I asked them to send the digital data as it is from the USB terminal.<\/p>\n
It is converted to analog with a music DAC and converted to an audio quality music signal.<\/p>\n
That’s the basic idea of \u200b\u200bPC audio.<\/p>\n","protected":false},"excerpt":{"rendered":"
