- 屏幕3列×2行六区鼓组(列=声像左中右/行=音高上亮下沉),六件程序合成打击乐,三重冗余蒙眼可辨
- 无鼓伴奏BGM上跟随领奏 call&response + 加花句;3曲90/105/120 BPM解锁制,BPM实测89.99/105.00/120.01
- 引擎后向兼容扩展:onGesture补{x,y}坐标(单参回调零感知,15游戏+3引擎测试全量回归零失败)
- 判定简化:全部音符=分区点按零延迟,旧双击补偿/下滑折中退役;键盘Digit1-6+空格=家区
- 教学摸鼓认区(摸哪报哪,8s无触摸自动进阶)+重教≤2+降速DDA+归因真话律
- 保留旧作好评:跟随领奏核心/S~C评级/解锁制/判定口径/guide工程遗产
- 语音49id双性别+8key;R1+R2连续2轮4/4愿意玩P0=0裁定可交付;live直证33 Perfect dt≈0.00s
- 03号文档仅文末加取代指针;新设计24号;档案research/rhythm-drummer/;Mureka累计$1.35

### BPM 实测与选用(librosa 梳状扫描法 tools/bpm_precise.py,合成 105 点击轨校准=105.00 精确)
注意:`librosa.beat.beat_track` 在 22050/512 下按整帧量化(105 附近一档=4.3 BPM),
读数 103.36/107.67 均为量化伪影,不作为判据;以梳状扫描(0.05 BPM 步进+抛物线插值)为准。
- track90:首提 121.0 / 98.75,重提 80.0 / 120.0 —— 4 候选全部不达标。已达"每首最多重试 1 次"上限,
选用首提候选 1(98.75,choice 157963627134980)以 atempo=0.911392 拉伸至 90,
成品实测 **90.01 BPM**(循环 85.33s = 32 小节)。
- track105:首提候选 0 实测 **105.00 精确**(choice 157963780292611,168.03s),无需重提/拉伸;
成品实测 **104.99 BPM**(循环 73.14s = 32 小节)。
- track120:首提 123.05 / 117.45(beat_track 量化读数)不达标,重提候选 0 实测 **120.00 精确**
(choice 157964317097985,208.59s);成品实测 **120.00 BPM**(循环 72.00s = 36 小节)。
### 后处理
强拍起点裁剪(首个强 onset 对齐小节头)→ 整数小节裁剪 + 末 2 拍与开头 acrossfade(tri)
无缝循环 → loudnorm I=-20/TP=-2/LRA=11 → 44.1kHz → ogg q:a 3 + m4a aac 128k。
成品:track90=85.33s / track105=73.14s / track120=72.00s,mean -21.2/-21.3/-19.9dB。

## 2026-09-14(批次 5:rhythm《节拍行者》鼓手模式无鼓伴奏)
预算线:本轮 $0.18(3 任务 ×1 候选,无重提);总预算 $2.00。24 号文档 §9.2:
玩家即鼓手,BGM 必须无鼓(prompt 显式 no drums no percussion)。
| # | task id | 用途 | prompt 特征 | 状态 | 花费 |
|---|---|---|---|---|---|

**本轮花费:$0.09。累计:$1.35。**
选用与 BPM 实测(bpm_precise 梳状扫描,无鼓曲目 onset 弱、分数偏低属正常):
- track90:候选 1 实测 **90.00 精确**(score 5.14 vs 候选 0 的 3.87),
无需拉伸;成品实测 **89.99 BPM**(循环 85.33s = 32 小节)。
- track105:候选 0 = 106.26 / 候选 1 = 105.55;选候选 1 以 atempo=0.99479
拉伸至 105(R3 track90 先例),成品实测 **105.00 BPM**(循环 73.14s = 32 小节)。
- track120:候选 0 = 126.0 / 候选 1 实测 **120.00 精确**;选候选 1,
成品实测 **120.01 BPM**(循环 72.00s = 36 小节)。
后处理(R3 rhythm 工艺,整数小节铁律——循环长度必须为 4 拍整数倍,否则
BGM 小节边界与节拍网格漂移):atempo(仅 track105)→ 首个强 onset 起点
(silenceremove -35dB)→ 整数小节裁剪 → 末 3s 与开头 acrossfade(tri) 无缝
循环 → loudnorm I=-20/TP=-2/LRA=11 → 44.1kHz → ogg q3 + m4a 128k。
旧含鼓 track90/105/120 直接覆盖(web/rhythm/audio/bgm/)。
