You may not know how a DAC works and why it is used, but almost everyone uses a DAC in their daily life. Surprised? Let’s see how
What is a DAC, and why do you need one?
DAC stands for the digital-to-analog converter.
If you are using any audio or video device, you are using DAC.
Every digital device like music players, televisions, CD players, game consoles store audio in digits (0 and 1) formats. Human ears cannot understand this language because the digits are only intended for machines, so the digital signal needs to be converted to analog so that we humans can enjoy the sound.
Thus, a digital-to-analog converter (DAC) is responsible for converting digital signals into audio.
Today’s computers, tablets, smartphones, LED televisions, and Blu-ray players have built-in DACs.
Why should you buy an external DAC?
The main reason is that the internal DAC does not produce a high-precision audio signal and does not eliminate possible noise interference in the signal.
If you are a music lover or want to enjoy every part of the audio frequency, the built-in DAC might let you down.
An external DAC ensures that every digital bit is converted into the appropriate audio signal. Nowadays, DACs are also available with audio frequency control to change the sound beats to suit your musical tastes. DACs also have amplifiers to boost the output signal for excellent, smooth quality.
Let’s take a look at the best DACs on the market.

How do you choose the best DAC (digital to analog converter) for your audio system, headphones, or desktop?
Choosing the best DAC from the many DACs available in the market is a bit of a challenge, but if you shortlist based on the following 5 points, you will end up buying a good DAC:
Noise Reduction: Look for filter technology that filters out hiss or noise
Portable or Desktop: You don’t need to buy a big DAC to enjoy high-quality audio. You can buy a pocket or portable DAC. Portable DACs are more economical than desktop DACs.
Sample rate and bit depth: These two parameters determine the quality of the audio signal. High-resolution music requires a higher sample rate. Typically, high-resolution music files have a sampling rate of 768 kHz. A high bit means a higher quality audio signal; for example, a 16-bit data set contains more information than an 8-bit data set.
What kind of music would you like to listen to? It is possible that certain DACs do not support all file types. There are various music sources such as FLAC (free lossless audio codec), Ogg Vorbis, ALAC (Apple lossless audio codec), MQA, CD, DSD, and others.
Compatibility: where you connect your smartphone, home theater system, desktop computer, MAC or Windows laptop, etc. Ensure the DAC has the necessary ports and connectors to connect to your device.
Most DACs have a built-in headphone amplifier, which would be the best option as buying a separate DAC and amplifier can be expensive and inconvenient.
Since your smartphone or Personal Computer has a built-in DAC, it may not offer high-precision audio. A DAC with a built-in headphone amplifier is a significant improvement in such cases.
Whether you’re looking for a portable DAC for your phone or the best system for your home, you need to invest in a quality DAC.
