Intro to high-resolution audio
Digital music that gets back to great sound
In this article: We cover the basics of high-res audio
It's the small details that make your music come alive — the sizzle of brushes on a cymbal; the sound of fingers gently gliding along guitar strings; a quick intake of breath before the singer starts. Want to hear all those hair-raising details? Give hi-res audio a try.
Hi-res audio files sound better than CDs. And they sound way better than the compressed digital audio files we get from iTunes, Amazon, and most music streaming services. They come much closer to capturing all the nuances of the original performance.
Great sound with digital convenience
High-res audio formats give you excellent sound quality and the convenience of digital audio files. High-res music files are a bit larger since they retain all the audio information from the original recording, so they take up more space on your hard drive and require more bandwidth for streaming.
These tracks can cost a little more, too. But if music is your passion, it's a small investment towards increased listening pleasure.
High-res audio specs
Recordings are converted to digital audio through a series of waveform samples.
The term "bit depth" tells you how detailed each sample is. High-res files usually have a depth of at least 24 bits.
The sampling frequency tells you how many samples were taken per second during the digitization process. More frequent sampling leads to smoother, more natural sound. High-res files have sampling rates up to 192 kHz.
Of course, all that extra information increases file size. A 24-bit/96kHz high-res music file, for example, is about three times bigger than a CD-quality file of the same music track.
High-resolution audio can provide much more musical detail than CD.
High-resolution audio file types — bigger and better
It's important to know which high-resolution file types are compatible with your system.
- Standard format for CDs
- Can be played on Windows® and Apple® computers
- Apple’s uncompressed audio format
- The most popular lossless compressed format
- Takes up about half the space of uncompressed files
- Not compatible with iTunes or Apple Music
- Apple's lossless compressed audio format
- Takes up about half the space of uncompressed files
- Not always supported by non-Apple devices
- Processes the audio signal as a stream of single bits (vs. PCM’s multi-bit chunks)
- Most high-res players convert DSD files to PCM for playback
- Some players support native DSD playback
- An additional encoding process that makes PCM and DSD files small enough for streaming
- Preserves all file information for playback through audio components with an MQA decoder
- Backward compatible: MQA-encoded files can be played through any audio equipment

Media players for high-res audio
iTunes can play AIFF and WAV files, but it's probably not the best choice if you're building a high-res music library. iTunes doesn't provide the best sound quality, and it doesn't support common high-res formats like FLAC.
Roon is a subscription-based music management system that provides extensive info about your music, including artist bios, photos, reviews, lyrics, and show dates.
