-早期八路展开、`-O2` 构建另做了 A/B/B/A：基线 26.73%、27.95%，候选 26.73%、26.54%。它支持“常速整页差异很小”的判断；最终 `-O3` 构建的结果单列于上表，没有混称同一构建。 - -## 局部计算 - -WSOLA 测试输入为节目中提取的 30 秒、48 kHz 双声道 float32 PCM，预热后取三轮均值。每种速率均逐字节比较基线和优化输出。 - -| 播放速率 | 基线耗时 | 优化耗时 | 输出 | -| --- | ---: | ---: | --- | -| 1× | 0.80 ms | 0.73 ms | 完全相同 | -| 0.9× | 378.64 ms | 93.47 ms | 完全相同 | -| 1.01× | 337.89 ms | 82.53 ms | 完全相同 | -| 1.2× | 283.87 ms | 69.32 ms | 完全相同 | -| 2× | 176.91 ms | 41.93 ms | 完全相同 | - -非 1× 拉伸耗时降低约 75%。优化同时计算八个相邻候选的相关性，保留穷举范围、每个累加器的求和顺序和并列候选的选择顺序，没有降低音质或缩小搜索范围。 - -TS 解复用/封装对完整爱电影录制运行，三个网络分块尺寸的输出摘要分别核对。以下为三次计时的中位数。 - -| 分块大小 | 基线 | 优化 | 耗时下降 | -| --- | ---: | ---: | ---: | -| 1,316 字节 | 110.02 ms | 103.23 ms | 6.2% | -| 18,800 字节 | 104.57 ms | 94.97 ms | 9.2% | -| 65,536 字节 | 100.98 ms | 92.14 ms | 8.8% | - -三个尺寸各自的 MP4 初始化段、媒体段和 MP2 输出 SHA-256 均与基线相同。不同分块尺寸可能影响 MP4 分段，因此只比较同一分块尺寸前后的摘要。较早的重复测量耗时下降约 9–11%；局部小基准存在波动，不把它当作整页 CPU 降幅。 - -## 兼容性与取舍 - -- 保留普通 HTTP、MSE 静音音轨、MP2、音画同步、变速、暂停/恢复、seek、频道切换和后台恢复。不引入 AudioWorklet、SharedArrayBuffer 或其他只在安全上下文可用的 API。 -- WSOLA 回归覆盖多种采样率、单/双声道、细碎输入、时长、音调、静音和 reset。TS 回归覆盖 188/192/204 字节包、PCR 回绕和 discontinuity。 -- 正式 `-O3` WASM 对真实节目的 MP2 数据分别按 97、576、4096 字节分块解码，三种分块的 PCM 均逐字节等于基线，也彼此一致，验证了跨输入块的帧缓存。 -- 在真实 HTTP 浏览器中验证了启动、暂停后时钟停止、恢复、回退 seek、1.2×、切到后台再返回、重新加载频道和销毁，无播放错误。 -- SIMD 构建、十六路展开和更大的 Web Audio latency hint 没有表现出值得增加兼容分支或代码量的整体收益，未采用。 -- 常速下剩余开销主要在浏览器的媒体解码、音频输出和视频合成；1080i 在此 Chrome 环境走软件视频解码。上述结果不代表其他浏览器的视频解码能力，也没有直接测量手机温度或电池功耗。 -
