# Mux Voice Track / 合一旁白轨 ## When to use / 何时使用 After tts-batch when a single continuous voice track is needed for timing reference or radio cut. 批量配音完成后，需要一条连续旁白轨用于时间线对齐或纯音频版本。 ## Inputs / 输入 - `workspace/voice/manifest.json`. - `--gap-ms` default 350. ## Output / 输出 - `workspace/voice/master.wav` (48 kHz, 24-bit, mono). - `workspace/voice/master.cues.json`: per-segment start/end timestamps. ## Steps / 步骤 1. Sort manifest by segment id. 2. Build ffmpeg concat list with silence padding `--gap-ms` between entries. 3. Run ffmpeg concat + loudnorm to -16 LUFS. 4. Emit cues JSON. ## Examples / 示例 ``` ffmpeg -f concat -safe 0 -i list.txt -af loudnorm=I=-16:TP=-1.5 -ar 48000 master.wav ``` ## Failure recovery / 失败回退 - If any seg MP3 missing, fail loudly and list missing ids. - If loudnorm fails (very short clip), fall back to volume normalization.
