"""《星环舰长》程序合成音效（22-bridge.md §3.2/§9.2，27 基 id SYN + 8 pan 派生）。
|
||||
|
||||
落盘：staging wav → tools/gen_bridge_syn_wav/<id>.wav（44.1kHz 立体声）；
|
||||
成品 → web/bridge/audio/sfx/<id>.{ogg,m4a}（tools/bin/ffmpeg 双格式）。
|
||||
SA3 危机签名 4 件（center）由 tools/gen_bridge_sfx.sh 生成到同 staging 目录，
|
||||
本脚本负责：其余 27 件 SYN + sig_* 的 _l/_r pan 派生（ffmpeg stereotools sbal ±0.8，
|
||||
dungeon mob_step 工艺）+ 全部 39 件的编码与 QC。
|
||||
|
||||
规格要点（§3.2，节奏写死、playtest 逐毫秒断言）：
|
||||
巡检音 2.0s、间隔 0.4s；引擎 60-110Hz 低频族 / 护盾 1.2-2.8kHz 中高频族 /
|
||||
扫描 800-1600Hz 硬声像左 / 武器 400-900Hz 硬声像右（固定舰桥布局，pan 烤进资产）；
|
||||
离线 = sys_offline 180Hz×3 慢平音全系统共用；方位尾音 dir_bow 600→1200Hz 上行 /
|
||||
dir_stern 1200→500Hz 下行 0.3s。
|
||||
|
||||
QC（asset-pipeline 标准）：one-shot 去直流 + 首尾 8ms cos² + 编码后解码回读
|
||||
真峰值 ≤ -3dBFS（超限自动降档重编）；pan 派生与扫描/武器音做声道能量断言
|
||||
（目标声道占比 >90%）；另把实测时长写 durations.json 供 playtest 资产侧断言。
