Why Hi-Res

差别在哪里，用数据看清楚

以下参数均来自公开标准与采样理论；动画为原理演示，已对差异做视觉放大，便于一眼看懂。

Data Rate数据量 · 对比 128kbps MP3

72×

每秒 9,216 kbps 的数据洪流，MP3 只留下 128 kbps

24bit/192kHz 立体声 PCM 为 9,216 kbps，是 128kbps MP3 的 72 倍；即使对比 CD 的 1,411.2 kbps，MP3 也舍弃了约 90.9% 的数据。

依据：码率 = 采样率 × 位深 × 声道数

Sampling Rate采样密度 · 对比 CD 44.1kHz

4.35×

每秒 192,000 次采样，超高频细节被完整记下

同一段 0.5 毫秒的波形：Hi-Res 取 96 个点，CD 规格只取 22 个点。为避免混叠，CD 必须在录制前滤除 22.05 kHz 以上的成分——红色区域就是被滤掉的部分。

依据：奈奎斯特–香农采样定理；IEC 60908（CD-DA）

Bit Depth量化精度 · 对比 CD 16bit

256×

放大 256 倍：16bit 的 1 级里藏着 24bit 的 256 级

2²⁴ ÷ 2¹⁶ = 256。将波形持续放大，16bit 的台阶最终变成一条直线，24bit 仍在精细地追踪信号。理论动态范围由约 96 dB 提升到约 144 dB。

依据：线性 PCM 量化；动态范围 ≈ 6.02 × N dB

Frequency Response频响上限 · Hi-Res 96kHz

96k

频谱瀑布：三刀切下，差别一目了然

Hi-Res 记录到 96 kHz；CD 规格在 22.05 kHz 处被硬性截断；128kbps MP3 编码器通常在约 16–17 kHz 处低通，并按心理声学模型丢弃部分高频，形成“空洞”。

依据：IEC 60908；ISO/IEC 11172-3；LAME 编码器默认低通参数

[2] IEC 60908CD-DA「红皮书」标准：16 bit / 44.1 kHz / 双声道 PCM，1,411.2 kbps。
[3] JAS Hi-Res日本音频协会 Hi-Res Audio 标识：支持 96 kHz / 24 bit 及以上格式。
[4] ISO/IEC 11172-3MPEG-1 Audio Layer III（MP3）：基于心理声学模型的有损感知编码。
[5] FLACFree Lossless Audio Codec：无损压缩，解码后与源 PCM 数据逐比特一致。

说明：人耳可闻范围通常为 20 Hz – 20 kHz，超过 20 kHz 成分的可闻性在学界仍有讨论；24bit 的实际动态范围受录音与回放器件底噪限制。最终听感同时取决于录音制作与回放设备。
