High-Resolution Audio

What is High-Resolution Audio?

the difference between hearing and listening

High-Resolution Audio is offering quality surpassing that of CD (16bit/44.1kHz).

The superior quality of High-Resolution Audio lets the listener discover subtle details and nuances within the music, the same way you would if you were actually at a recording studio or live performance.

In other words, High-Resolution Audio takes you closer to the original, to provide an excitingly satisfying listening experience.

History Repeats Itself

Just as HDTV revolutionized television viewing with its leap in picture quality, High-Resolution Audio enables a whole new level of listening enjoyment. So if you’re wondering if your ears really need High-Resolution Audio, just ask your eyes if they’re willing to go back to the old standard definition TV. From the early days of audio recording, engineers have always pursued the highest quality with the technology that was available to them. Then came the CD, which afforded high quality sound but with capacity limited by the physical size of the disc. Digital music then broke free of the disc, but due to storage and bandwidth limitations, data needed to be compressed and lost some quality. Now we have come full circle, finally with digital audio technology enabling capture of original analog sources—the performances themselves, exactly as the artists intended—with lossless quality.

Sampling Specifications

High-Resolution Audio, often denoted as "192kHz/24bit" or something similar, is made by digitally sampling an original analog audio source. The rate at which a sampling is performed per 1 second is called the sampling frequency, expressed in Hz. Digitizing refers to the process of quantizing the sampled signal into binary digits consisting of 1’s and 0’s, and is expressed as "bits". Here, a higher number of bits means a result that is closer to the original source.

CDs are standardized at 16bit/44.1kHz. There is no such single standard for High-Resolution Audio, however the most commonly used specs are 24bit/96kHz and 192kHz/24bit. An alternative means for digitizing an analog source is a method called DSD (Direct Stream Digital) which quantizes in 1 bit increments at an extremely fast 2.8MHz or higher, and is expressed as DSD 1bit/2.8MHz, etc.

File Formats / Lossless Codecs

A variety of different file formats exist for High-Resolution Audio.

Due to the amount of data carried in High-Resolution Audio files, the file sizes tend to become very large. In order to reduce file size down to manageable levels without sacrificing quality, the following types of compression have been developed.

  • DSD(DFF) is the DSD file format used in professional equipment for the manufacture of Super Audio CDs.
  • DSD(DSF) is a PC-friendly format created for use in VAIO PCs, and a DVD burned using DSF data is referred to as a "DSD disc".
  • WAV is the audio file format developed for Windows®.
  • AIFF is the audio file format developed for Macintosh computers.
  • FLAC stands for Free Lossless Audio Codec, and as the name implies, it enables encoded (compressed) audio data to be decoded and restored to its original state, affording what is called "lossless compression".
  • ALAC (Apple Lossless Audio Codec), , also commonly known as "Apple Lossless", is lossless compression technology.
