We’ll discuss how digital to analog converters (DAC) work and their benefits, especially for music lovers. Keep reading!

What is a DAC?

Whether you’re listening to a CD, WAV file, or an MP3, you can thank the digital to analog converter (DAC) for processing all of the magic. Without DACs, we wouldn’t be able to enjoy the convenience of digital audio. Simply, a DAC converts digital data into analog audio signal. From there, it sends the analog signal to an amplifier. The DACs used in smartphones and tablets are generally basic and low quality. They produce sounds that are just good enough but often lack depth and clarity.

How the Process Works

Here’s the ins and outs of how DACs work.

  1. A musician records music using microphones or instrument cables. Voices and instruments are recorded as analog audio signals.
  2. Recording engineers use a DAC to transform the analog signals into digital signals. The digital signals are stored as a digital audio file aka song.
  3. When you choose to play a song, a DAC decodes the digital signals, converting them back into analog audio.
  4. The DAC then sends the converted signals to an amplifier. The amplifier then sends music through your headphones or speakers.

Know that you know what a DAC is and how it works, another question you’re probably wondering is whether or not the DAC you have is good enough.

All About External DACs

If you’re using a DAC in a mobile device, chances are that you’d enjoy your sounds much more if you use an external DAC. Low quality DACs can cause jitter during playback because of timing sequence issues. Because internal DACs aren’t designed to deal with timing issues, they tend to produce a lot of jitter. But, external DACs are designed to provide high quality playback. In turn, you can better enjoy your music without the risk of lag or jitter.

There is a DAC for every device that can be play audio. When choosing an external DAC, you need to choose the one that fits the device that you’re looking to use for playing music. For example, if you want to use the audio from a laptop or desktop computer, you’ll want to find a USB DAC. A USB DAC can also be used for headphones. When using a USB DAC, be sure to assign the audio out to the DAC.

In stores you’ll also find DACs for smartphones, tablets, as well as home stereo systems. There are also DACs meant just for headphones! No matter your listening device, using a DAC will take your experience to a whole new level. There’s nothing better than great sound.
