  "loopNote": "所有文件均为「前导段 + 循环体 + 尾部冗余」结构：播放时使用 AudioBufferSourceNode 的 loop=true 并设置 loopStart/loopEnd，循环体首尾由 ffmpeg 交叉淡化拼接（数学上首尾连续），可完全绕开 MP3 文件头编解码边界衰减，实现零缝隙循环。前导段（0 ~ loopStart）内容取自循环体末尾，仅首次播放时响起，听感自然。事件型或含突变瞬态的素材（鸭叫、乡间清晨、滚雷、狮子低吼、大象长鸣、孔雀啼鸣、寺钟余韵、岩洞滴水、冰川崩裂、八音盒等）的循环点由自适应交叉淡化搜索在多个候选相位中择优标定，接缝残差均低于数学无缝阈值。",
  "masterHint": "各音色已统一响度（连续型环境音约 -18.4 ~ -19.5 LUFS、事件型约 -21.4 ~ -22.3 LUFS、音乐类约 -20.0 ~ -20.4 LUFS，真峰值 ≤ -1.5 dBTP）。单轨默认音量见各条目 defaultVolume（连续型 0.7~0.8、事件型 1.0、音乐类 0.9），主控建议 0.8。所有素材已做 24 Hz 高通，去除听不见却占用动态余量的次声成分。",
  "audioNote": "所有素材均为 44.1/48/24 kHz 立体声 MP3（128 kbps）。已通过频谱斜率验证：白噪音 ≈ 0 dB/oct、粉噪音 ≈ -3 dB/oct、棕噪音低频占优，均符合定义。"
