DAC, which stands for Digital to Analog Converter, is a chip that converts digital audio information into analog audio signal. In simple words, DAC is a decoder that provides a much better analog audio signal by increasing the sound quality.
Wait a minute, what is digital and what is analog? What does that have anything to do with us? If you are a total beginner to this, please allow me to explain to you in simple words. There are a lot of detailed articles out there, but we want to make it simple here.
First of all, let’s look at analog and digital signals. To put this in a simple way, we can think of analog as a continuous transmission of audio and image that can be greatly affected by distance or surroundings; whereas digital is non-continuous and usually can be seen as the binary code in computer or cell phone system. (as the image above)
Have you noticed that? Although computers and smartphones systems have a non-sequence digital signals still broadcast realistic sounds? That is because DAC is more than just a conversion between digital and analog. During the conversion, it enhances the signal and logic operation must the performed to restore the signal to its original state as undistorted as possible to optimize the music in your ear. So with the help of DAC, the music sounds better, clearer and as undistorted as possible. We can go into details and more technical words on how the technology works, but we are trying to make this as simple as possible.
Since we have got this far, one thing I would like to bring up is that all the major smartphone brands including HTC, Mi, Huawei, Google have removed the 3.5mm headphone jack and use one single type-C connector. This revolutionary move has changed the whole market trend of DAC chips, the need of DAC has then increased dramatically. Therefore from that moment on, all the adapters with a DAC chip becomes a necessity if you own one of those type-C mobile phones and demand for a High-Res sound quality.
Below, we can simply show you how DAC will work for us.
Hopefully now you have a better understanding about DAC as well as the basic principles that causes music to sound more realistic.
