Pulse Density调制方式 · 对比多比特 PCM
1bit
不记录每个点的数值，只记录脉冲的疏密
DSD 以 1 bit 的 Σ-Δ 调制记录声音：电平越高脉冲越密，电平越低脉冲越稀疏。回放时只需一道模拟低通滤波，就能把脉冲流还原为连续波形。
依据：Σ-Δ 调制原理；Sony / Philips Scarlet Book（SACD）

Why DSD
不是更多的位，而是更快的脉冲
DSD 与 PCM 是两种不同的数字化思路。以下参数来自 SACD 规格与 Σ-Δ 调制原理；动画为原理演示，已对差异做视觉放大。
Sampling Rate采样频率 · 对比 CD 44.1kHz
64×
每秒 2,822,400 次：CD 采样一次，DSD 已采样 64 次
DSD64 的采样频率为 2.8224 MHz，恰好是 CD 44.1 kHz 的 64 倍；DSD128、DSD256 依次再翻倍。极高的采样频率让 1 bit 也能表达细腻的电平变化。
依据：2,822,400 ÷ 44,100 = 64；Scarlet Book
Noise Shaping音频带动态范围 · 20 Hz–20 kHz
120dB
噪声整形：把量化噪声推到听不见的超声区
1 bit 量化本身噪声很大，DSD 通过噪声整形把噪声能量搬移到 50 kHz 以上，使 20 kHz 以内的音频带噪底低至约 −120 dB，频响可延伸至约 100 kHz。
依据：SACD 规格（音频带动态范围 ≥ 120 dB，频响 DC–100 kHz）
Signal Chain数字滤波级数 · 对比 PCM 链路
−2
更短的信号链：省去抽取与插值两道数字滤波
多数 ADC 内部本就是 Σ-Δ 1 bit 结构。PCM 需要先抽取滤波转为多比特，回放时再插值；DSD 直接保存 1 bit 流，原生回放时信号链更短。
依据：Σ-Δ ADC / DAC 架构；DSF / DSDIFF 文件规范
- [1] Scarlet BookSony / Philips SACD 规格（1999）：DSD64，1 bit / 2.8224 MHz。
- [2] Σ-Δ 调制以过采样 + 噪声整形实现 1 bit 量化，把噪声移出音频带。
- [3] DSF / DSDIFFSony DSF 与 Philips DFF 是 DSD 的两种主流文件封装。
- [4] DoPDSD over PCM 开放标准：通过 PCM 通道无损传输 DSD 数据。
- [5] JAS Hi-Res日本音频协会 Hi-Res 标识：DSD 2.8 MHz 及以上符合认证。
说明：DSD 原生播放需要解码器支持 Native DSD 或 DoP；不支持时，播放软件会将其实时转换为 PCM 播放。噪声整形产生的超声噪声通常由解码器的模拟低通滤波滤除。最终听感同时取决于录音制作与回放设备。
