Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audiobook-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

依赖检查

必须先检查 edge-tts 是否安装:

which edge-tts

如果未安装,提示用户:

❌ edge-tts 未安装

请执行以下命令安装:
pip install edge-tts

工作流程

章节文件 → 文本处理 → TTS纯文本 → edge-tts → MP3音频 + SRT字幕

步骤1: 准备 TTS 文本

读取章节文件,去除格式标记,输出纯文本。

处理规则:

  • 去除 YAML frontmatter (--- 包裹的内容)
  • 去除 Markdown 标记 (#*** 等)
  • 去除行号标记 (数字→)
  • 规范化段落间距(合并多余空行)
  • 保留章节标题

输出: releases/{project_id}/tts/scripts/0001.txt, 0002.txt, ...

步骤2: 生成音频

直接调用 edge-tts 命令,默认增量生成(只处理有变更的文件):

# 增量生成:只处理需要更新的文件
for f in releases/{project_id}/tts/scripts/*.txt; do
  name=$(basename "$f" .txt)
  audio_file="releases/{project_id}/tts/audio/${name}.mp3"

  # 增量检查:跳过已是最新的文件
  if [ -f "$audio_file" ] && [ "$audio_file" -nt "$f" ]; then
    echo "跳过 ${name} (已是最新)"
    continue
  fi

  echo "生成 ${name}.mp3 ..."
  edge-tts --voice zh-CN-YunxiNeural \
    --file "$f" \
    --write-media "$audio_file" \
    --write-subtitles "releases/{project_id}/tts/subtitles/${name}.srt"
done

强制全量生成 (使用 --force 参数时):

for f in releases/{project_id}/tts/scripts/*.txt; do
  name=$(basename "$f" .txt)
  edge-tts --voice zh-CN-YunxiNeural \
    --file "$f" \
    --write-media "releases/{project_id}/tts/audio/${name}.mp3" \
    --write-subtitles "releases/{project_id}/tts/subtitles/${name}.srt"
done

edge-tts 参数

--voice 音色 zh-CN-YunxiNeural
--file 输入文本文件 input.txt
--write-media 输出音频文件 output.mp3
--write-subtitles 输出字幕文件 output.srt
--rate 语速调整 +10%-10%
--volume 音量调整 +10%-10%

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
