I want to listen to high-resolution music on my smartphone or music player.
I want to listen to music with better sound quality!
DAC is what we would like you to use.
DAC stands for digital-to-analog converter.
If you listen to high-resolution music on your phone or music player, you need one!
The sound quality will improve, and you will be able to hear sounds that you could not hear before without having to change earphones.
Let's take a closer look at what a DAC is and why it improves sound!
Role of DAC
You probably listen to music on your smartphone or music player.
The music you are listening to is stored as electronic data.
But in reality, you hear a variety of sounds coming from your headphones.
A DAC is a device that converts digitally stored music data into actual sound.
Digital values are discrete values, a collection of data made up of 1s and 0s
Analog values are actual physical quantities
It is difficult to say, isn't it?
A music file does not store the sound you hear as it is, but is composed of a collection of 1s and 0s.
So what converts those 1s and 0s into music is something called a DAC!
If it can play music data, then your smartphone or music player uses this DAC!
Why does using a DAC improve sound?
If you use a DAC, it will improve the sound, but isn't it already being used in smartphones and music players?
I think so, don't you?
That's right. It is already in use.
Then why does using a DAC improve the sound? That's because the DACs used in smartphones are crappy!
Especially if you want to play high-resolution sound sources, the DAC in your smartphone or music player may not support high-resolution sound data.
If you are using such a device, even if you have the data, it cannot be converted to analog and you will lose the sound that you were originally supposed to be able to produce.
Therefore, if you want to play back high-resolution audio, you need to use a DAC that supports it and convert all of the digitally stored data into analog values.
The DAC also has a circuit that transmits the analog signal after converting the music data from digital to analog.
Noise can also be added here, so the sound quality of music data that can be converted from digital to analog without any extra data other than high-resolution will also change.
How to use DAC
A DAC is a machine that converts digital signals into analog signals, so when connecting a DAC to a smartphone or music player, it must receive music data in the form of digital signals.
For example, the signal taken from a 3.5mm headphone jack is analog, so it will have already passed through the DAC of the smartphone or music player.
This makes it meaningless to use a headphone amplifier with DAC.
Note that you need to transfer the music data directly via USB cable.
Since the DAC is a device that converts digital signals to analog, it must then be connected to an amplifier to amplify the actual sound.
This is what is called a headphone amplifier.
A DAC is not a stand-alone device, but should be used as a set with an amplifier.
Recently, many DACs and headphone amplifiers are sold as an integrated unit for smartphones and music players.
Recommended DAC
For use with a smartphone or music player, a headphone amplifier with DAC is recommended.
For use in the house, though, a configuration of a stationary DAC and a stationary amplifier is also good.
It is also important that it be small if you want to use it on the go, as you will simply have more things to take with you.
Many headphone amplifiers with DACs that can be plugged directly into the USB port are also available by type, so they are highly recommended.
