# Demo 音频 v2：录音素材、混音及合成口播

核实与替换日期：2026-09-12。此版本已经删除上一轮 11 个音频文件，使用新的近远枪声、柴油车、拟音、音乐及本地生成口播。所有内容用于非官方教学 Demo，不代表 WARDOGS 原作音效、枪械声学、医疗操作或配乐。

| 本地文件 | 作者 / 来源 | 许可 | 加工与用途 |
|---|---|---|---|
| near-shot-a/b.wav, far-shot-a/b.wav | Ben Jaszczak、Brian Nelson、Kevin Heras、Matthew Nanney；[The Free Firearm Sound Library](https://opengameart.org/content/the-free-firearm-sound-library) | [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) | 新选 AK-47 近距离 C_28P.wav（0.608、3.254 秒各截 0.85 秒），中距离 C_31P.wav（0.334、4.398 秒各截 1.85 秒）；与旧版 AR-15 录音不同。转 mono 44.1kHz PCM16，70Hz 高通、峰值限制、150ms尾部淡出。近枪与远枪按距离分别触发，不将同一近枪简单降音量当远枪。 |
| reload-mechanical.wav | Brian MacIntosh / BMacZero；[Gun Reload Sound Effects](https://opengameart.org/content/gun-reload-sound-effects) | CC0 1.0 | clipload2.wav、singlebullet1.wav、clipload1.wav 依次在 0、0.45、1.2 秒编排成换弹机械声；转 mono 22.05kHz PCM16。 |
| gravel-a/b/c/d.wav | Corsica_S，Iwan Gabovitch / qubodup 提取；[42 Snow and Gravel Footsteps](https://opengameart.org/content/42-snow-and-gravel-footsteps) | CC0 1.0（作者明确同意重新发布） | Walking_on_snow_covered_gravel_01–04.flac，转 mono 22.05kHz，90Hz高通、7kHz低通；多变体避免每步相同。 |
| wood-hammer-a/b.wav, radio-click.wav, metal-hit.wav | rubberduck；[100 CC0 metal and wood SFX](https://opengameart.org/content/100-cc0-metal-and-wood-sfx) | CC0 1.0 | wood_hammer_01/02.ogg、tools_03.ogg、metal_hit_05.ogg，转 mono 22.05kHz并限制高频。施工改为短木锤敲击，不再用旧版铁砧长鸣。radio-click 为机械按钮提示，不含提示旋律。 |
| diesel-idle.mp3, diesel-load.mp3 | chlund；[Diesel engine starting revving and stopping](https://freesound.org/people/chlund/sounds/500193/) | CC0 1.0 | 作者用 Zoom H1n 录制 Citroën Jumpy 柴油机；从公开HQ预览切取 3–9秒怠速、10.8–12.8秒负载段，循环接缝交叉淡化，96kbps MP3。运行中按车速交叉混合两个不同录音段，小幅变速，避免单个蜂鸣循环大幅变调。 |
| defib-charge.mp3, defib-discharge.wav | reg7783；[defibrillator.wav](https://freesound.org/people/reg7783/sounds/321800/) | CC0 1.0 | 作者以旧相机闪光充电与泡沫垫拍击制作医疗拟音。公开HQ预览按2.45秒分出充电/释放；限制高频与音量。不是临床设备操作指引或原作声效。 |
| cannon-blast.mp3 | SamsterBirdies；[Cannon explosion sound 4](https://freesound.org/people/SamsterBirdies/sounds/621003/) | CC0 1.0 | 作者由爆竹录音分层制作的炮击/爆炸设计。公开HQ预览转mono112kbps，30Hz高通、7kHz低通。背景远炮使用较远声像及滤波，不伪装玩家近处开火。 |
| field-wind.mp3 | SamuelGremaud；[WIND - 1](https://freesound.org/people/SamuelGremaud/sounds/547472/) | CC0 1.0 | Zoom H4N Pro 实录法国夏季林间风声。公开HQ预览 1–22秒切片，1秒交叉淡化接缝，96kbps立体声。与稀疏远处短连射/炮声共同形成战场环境层。 |
| enemy-spotted.mp3 | **Alexandr Zhelanov — Enemy spotted**；[原作页](https://opengameart.org/content/enemy-spotted)，[作者](https://soundcloud.com/alexandr-zhelanov) | **[CC BY 3.0](https://creativecommons.org/licenses/by/3.0/)** | 完整曲目从 MP3 转112kbps，首尾3秒交叉淡化为约164.8秒循环，运行时低音量混音；口播期间自动降低音乐。与旧版 Iron wasteland 不同。保留作者、原作链接、许可证及此修改说明；作者不代表认可本项目。 |
| guide-look/approach/board/deliver/capture/command/cover/defend/rescue/understand/complete/confirm/error.mp3 | 本项目原创英文脚本；**本地神经语音合成，非真人录音** | 脚本与生成输出按本项目 MIT；Piper程序/模型及数据来源如下 | Piper 2023.11.14-2 + en_US-ljspeech-high，语速0.98、句间静音0.14秒；转80kbps MP3，120Hz高通、6.2kHz低通、-17 LUFS标准化。人物引导每次进入步骤播放一次；不会每帧重复。 |

## 本地合成口播依据

- Piper（用于本地生成，不随网页分发）：https://github.com/rhasspy/piper ，MIT。
- 模型卡：https://huggingface.co/rhasspy/piper-voices/blob/main/en/en_US/ljspeech/high/MODEL_CARD ，模型仓库标注 MIT；该模型卡明确标注训练数据为 public domain。
- LJ Speech Dataset：https://keithito.com/LJ-Speech-Dataset/ ，Keith Ito、Linda Johnson / LibriVox；文本、录音、标注为 public domain。此处使用既有通用模型生成本项目指令，未模仿名人或冒充原作角色。
- 口播稿逐条见 `voice-script.json`。模型只在本地离线生成阶段使用，网页不加载模型、不请求远端TTS服务。

## 混音与可验证性

七条独立总线：weapons、foley、vehicle、ambience、music、voice、ui。默认music=0.22、voice=1、effects=1；effects内部按场景平衡。音乐在口播时降至28%，远处环境降至50%，不会盖住讲解；枪声保持独立动态。总输出有压缩限幅器。每轨都带独立 AnalyserNode，状态提供实际每轨 RMS 和采样事件数；总线RMS不再代替所有音轨的输出证据。

素材文件大小、时长、采样率、SHA-256 见 `manifest.json`。缺失或解码失败会反映在 samplesLoaded；不会谎报加载成功。所有采样均自本站同源分发，无运行时外部声音请求。
