一：Hi-Res brief introduction

Hi-Res, also called High Resolution Audio, also known as high-resolution audio, is the latest high-quality music standard proposed by SONY in 2014. The standard is defined as the sound quality above 44.1kHz / 16bit (CD sound quality), equal to or greater than the resolution of 192 kHz / 24bit. The Hi-Res AUDIO logo and the Hi-Res AUDIO WIRELESS logo are registered trademarks of the Japan Audio Association (Japan Audio Society, JAS) and are licensed by the JAS. We call the process of obtaining the Hi-Res AUDIO logo and the Hi-Res AUDIO WIRELESS logo used as Hi-Res certification.
