It’s time to talk about digital-to-analog converters, or DACs as they are more commonly known, if you want to get serious about sound. These components are essential to digital sound, and if you use hi-res or lossless audio formats, installing or upgrading a DAC could result in a noticeable enhancement to your audio. What you should know is as follows.
What is a DAC?
DAC, which stands for “digital-to-analog converter,” was previously discussed. Around the time we started transitioning from analog formats like vinyl records and cassette tapes to the digital sound files and formats that we frequently use today, these devices became an essential component of our music technology.
Records stores used small grooves cut into the vinyl to record sound waves. A tiny stylus (needle) inserted into these grooves vibrates, reviving the sound waves with a little assistance from your speakers and an amplifier. Similarly, cassettes accomplish this. However, digital audio is more difficult. The same digital building pieces that are used for everything from spreadsheets to video games are employed to store sound waves. You need a specialized piece of technology, the DAC, to convert those “bits” back into something you can actually hear.
In its simplest form, a DAC is just a microprocessor that has been created to read the zeros and ones contained in digital audio files and convert them into analog electrical impulses that can then be amplified and transmitted to your headphones or speakers so you can hear them. You may see it as the stylus of digital music, if that makes it simpler.
What’s an external DAC?
DACs can be found in everything from cellphones to gaming consoles because so many different types of devices are now capable of playing digital music. A gadget has a DAC if it can output sound through a built-in speaker or through a headphone jack. However, just as vinyl enthusiasts are the first to point out that not all turntable styluses are created equal, not all DACs are either.
Although it’s not the sole factor, a DAC can have a significant impact on how well your digital music sounds. Some DACs have limitations; they can’t decode all digital music files reliably or at their highest quality. Some file types won’t be playable by others at all. Then there are the DACs’ incredibly subtle characteristics, such as distortion, noise, and sensitivity, each of which has an effect on how you hear.
For listeners who want to get the most out of their music, this is a dilemma. You might have a high-resolution music file downloaded to your device or a membership to a streaming music service like Tidal, Amazon Music HD, Qobuz, and Apple Music that offers high-resolution audio. The results, however, will be much less than what you could be hearing because a low-quality DAC won’t be able to process these files effectively or won’t be taking as many samples to assure audio fidelity according to the music file.
You may still wish to purchase an external DAC despite the fact that your phone or computer almost definitely has its own DAC. Depending on your needs, external DACs come in a variety of sizes and designs. You might use a tiny DAC to connect to your smartphone or digital music player while traveling with headphones, or you could connect them to your TV, game console, or computer to improve the sound at home (more on this below). Your audio files and streams will sound their finest because to their sophisticated capabilities, flexible customization choices, and capacity to convert a broad variety of digital audio formats.
