Network Audio

Transporting listeners to the stage or studio where music is born

In the world of high-resolution audio, components must realistically recreate every detail, right down to the performer’s breaths, and the atmosphere of the studio or concert hall.
Today, a revolution in audio is making it possible to enjoy the overwhelming presence of original recordings in the comfort of your own home for a reasonable price.


Closing in on the ultimate in sound quality with high-resolution audio

The debut of high-resolution audio files that contain more than four times the data of CDs sparked great excitement and joy among all those who love music.
The sound quality made possible by that immense amount of data goes far beyond the limits of CD media to deliver a difference that is clear and surprising by every measure, including sound image localization, transparency, and resolution.

High-resolution audio

Amount of data per second (stereo)

  • 1.256kbps / Standard music file (AAC, 256 kbps)
  • 2.1411.2kbps / CD (linear PCM, 44.1 kHz, 16 bits)
  • 3.4608kbps / High-resolution file (linear PCM, 96 kHz, 24 bits)
  • 4.9216kbps / High-resolution file (linear PCM, 192 kHz, 24 bits)

Network audio: A new listening style

Anyone can now download high-resolution audio files with the ultimate level of quality from the Internet. With the debut of such files, we have moved into an era of “media-less” playback in which it is possible to download high-data rate music that has been freed from the recording capacity constraints of physical media such as CDs, store it on computer hard disks, and listen to it using dedicated players.

Network audio: The new mainstream

The shortcoming of this playback method is its interposition of a computer into the audio system.
Computers pose a variety of issues for audio purists, ranging from difficult connections and settings to complex operation and intractable noise issues.

These problems were resolved with the advent of network audio components that play audio directly from hard disks that are connected to networks (network-attached storage, or NAS).
Under this paradigm, audio files are stored in a library on an NAS device, and mobile handsets such as smartphones are used as controllers to intuitively download, manage, and play the files.
In this way, network audio has exceeded the CD in terms of ease of use.

The fidata HFAS1 is a network-attached storage (NAS) appliance designed specifically for network audio. This type of device, which is an essential part of any network audio setup, is known as a network audio server.
