It can be a daunting task to make heads or tails of digital audio formats.

What each has to offer, and how to choose the right one for your audiophile needs. This guide should help clear up any confusion about these formats.

Why Digital Matters To Audiophiles

In the venerable analog-vs-digital discussion, digital marches on but with higher-resolution fidelity and ease of access. But selecting the proper digital format is important for getting the best sound out of your gear, so you want to make sure you're getting the highest-quality audio your electronics can handle, and you're hearing your music the way the engineers and artists say it should sound. Some prioritize resolution ability, others compatibility, and some optimized file size. Your chosen format can also make a difference to your entire signal chain – from your transport or source device to your DAC and amplification.

CD (Compact Disc)

Overview:

The most popular format for digital audio is CD, which uses 16-bit 44.1kHz PCM audio. It’s not the highest-resolution option, to be sure, but plenty of well-mastered CDs sound fantastic, and their ubiquity means they’re also a safe bet for any collection.

  • Universal compatibility with players
  • Affordable and accessible
