日本Hi-res认证怎么办理？

Hi-res是由JAS(日本音频协会)和CEA (消费电子协会)制定的高品质音频产品设计标准

Hi-Res是High Resolution Audio的缩写,而High Resolution就是高解析力、高分辨率的意思,这个词在图像显示领域运用得比较多,比如说4k分辨率就可以High Resolution来形容, 如此-来, High Resolution Audio就是高分辨率音源的意思。

Hi-Res是评价它的Sony爸爸和飞利浦爸爸合力推出dsd音频的高保真超一流水平的形容词，有一流的音乐，自然也有一流的耳机，所以HR也用来表示频响范围超过5-40k hz的耳机。

现在Hi-res已经快成为高端音频设备必备的一个认证标志

Hi-Res随身影育具备了全音域、高码率的能力,意味着随身影音产品迈进一个新的时代。 更丰富的细节、采样深度更高,对音源的追求更上一层。对于硬件产品来说,如果你拥有出色的符合Hi-res认证的硬件产品.那么相比参数不够得到认证的产品来说拥有更加出色的表现。这些得到认证的耳机也-定都是市场中非常优秀的产品。
