Core Principles

核心原则

Loudness is Not Volume

响度不等于音量

  • LUFS (Loudness Units Full Scale) measures perceived loudness
  • Streaming platforms normalize to target LUFS
  • Too loud = squashed dynamics, fatiguing
  • Too quiet = listener turns up volume, loses impact
  • LUFS（Loudness Units Full Scale）用于测量感知响度
  • 流媒体平台会将音频归一化至目标LUFS
  • 响度太高 = 动态范围被压缩，听觉疲劳
  • 响度太低 = 听众会调高音量，失去冲击力

Universal Target

通用目标

Master to -14 LUFS, -1.0 dBTP = works everywhere
母带处理目标为-14 LUFS，-1.0 dBTP = 适用于所有平台

Genre Informs Targets

流派影响目标

  • Classical/Jazz: -16 to -18 LUFS (high dynamic range)
  • Rock/Pop: -12 to -14 LUFS (moderate dynamics)
  • EDM/Hip-Hop: -8 to -12 LUFS (compressed, loud)
For streaming: -14 LUFS works across all genres
See genre-presets.md for detailed genre settings.
  • 古典/爵士：-16至-18 LUFS（高动态范围）
  • 摇滚/流行：-12至-14 LUFS（中等动态范围）
  • EDM/嘻哈：-8至-12 LUFS（压缩度高、响度大）
对于流媒体平台：-14 LUFS适用于所有流派
详细流派设置请查看genre-presets.md。

Override Support

自定义预设支持

Check for custom mastering presets:
检查是否存在自定义母带处理预设：

Loading Override

加载自定义预设

  1. Call 
    load_override("mastering-presets.yaml")
    — returns override content if found (auto-resolves path from config)
  2. If found: load and apply custom presets
  3. If not found: use base genre presets only
  1. 调用 
    load_override("mastering-presets.yaml")
    — 若找到则返回自定义预设内容（自动从配置中解析路径）
  2. 若找到：加载并应用自定义预设
  3. 若未找到：仅使用基础流派预设

How to Use Override

如何使用自定义预设

  1. Load at invocation start
  2. Check for genre-specific presets when mastering
  3. Override presets take precedence over base genre presets (field-level merge)
  4. Only specify fields you want to change — unset fields inherit from built-in
Example:
  • Mastering "dark-electronic" genre
  • Override has custom preset
  • Result: Apply -3 highmid cut, 2.0:1 compression with 15ms attack, target -12 LUFS
  1. 在调用开始时加载
  2. 母带处理时检查特定流派的预设
  3. 自定义预设优先级高于基础流派预设（字段级合并）
  4. 仅需指定需要修改的字段 — 未设置的字段继承自内置预设
示例:
  • 对“dark-electronic”流派进行母带处理
  • 存在自定义预设
  • 结果：应用-3的中高频削减、2.0:1的压缩比（15ms启动时间）、目标-12 LUFS

Path Resolution (REQUIRED)

路径解析（必填）

Before mastering, resolve audio path via MCP:
  1. Call 
    resolve_path("audio", album_slug)
    — returns the full audio directory path
Example: For album "my-album", returns 
~/bitwize-music/audio/artists/bitwize/albums/electronic/my-album/
.
Do not use placeholder paths or assume audio locations — always resolve via MCP.
母带处理前，通过MCP解析音频路径：
  1. 调用 
    resolve_path("audio", album_slug)
    — 返回完整的音频目录路径
示例: 对于专辑“my-album”，返回 
~/bitwize-music/audio/artists/bitwize/albums/electronic/my-album/
。
请勿使用占位符路径或假设音频位置 — 始终通过MCP进行解析。

Mastering Workflow

母带处理工作流

Step 1: Pre-Flight Check

步骤1：预检

Before mastering, verify:
  1. Audio folder exists — call 
    resolve_path("audio", album_slug)
    to confirm
  2. WAV files present — check for at least one 
    .wav
    file in the folder
  3. If no WAV files found, report: "No WAV files in [path]. Download tracks from Suno as WAV (highest quality) first."
  4. If folder contains only MP3s, warn: "MP3 files found but mastering requires WAV. Re-download from Suno as WAV."
母带处理前，验证：
  1. 音频文件夹存在 — 调用 
    resolve_path("audio", album_slug)
    确认
  2. 存在WAV文件 — 检查文件夹中至少有一个 
    .wav
    文件
  3. 若未找到WAV文件，报告：“[路径]中无WAV文件。请先从Suno下载最高质量的WAV格式曲目。”
  4. 若文件夹中仅存在MP3文件，警告：“检测到MP3文件，但母带处理需要WAV格式。请从Suno重新下载为WAV格式。”

Step 1.5: Confirm Genre Settings

步骤1.5：确认流派设置

Before analyzing or mastering, confirm genre settings with the user:
  1. Look up album genre — call 
    find_album(album_slug)
    to get the genre from album state
  2. Present genre and ask for confirmation:
    • "This album is filed under [genre]. Should I use the [genre] mastering preset?"
    • If user wants a different genre, let them pick from available presets
    • If no genre found in state, ask the user to choose one
  3. Ask about per-track variations:
    • "Are all tracks the same style, or do any need different mastering settings?"
    • If the user identifies tracks with a different style (e.g., "track 5 is more of a ballad"):
      • Note which tracks need different treatment and what genre/settings to use
      • Master in two passes: main genre for most tracks, then override settings for the exceptions
  4. Record the decisions — note genre choices in the mastering report for the handoff
Per-track override workflow:
  • Master all tracks with the primary genre first
  • Then re-master override tracks by calling 
    master_audio
    again with the different genre and copying the re-mastered output over the previous version in 
    mastered/
分析或母带处理前，与用户确认流派设置：
  1. 查找专辑流派 — 调用 
    find_album(album_slug)
    从专辑状态中获取流派
  2. 展示流派并请求确认：
    • “该专辑归类为**[流派]。是否使用[流派]**母带处理预设？”
    • 若用户需要不同流派，让其从可用预设中选择
    • 若状态中未找到流派，请求用户选择一个
  3. 询问单轨差异：
    • “所有曲目风格一致，还是部分曲目需要不同的母带处理设置？”
    • 若用户指出部分曲目风格不同（例如：“第5首更偏向民谣”）：
      • 记录需要特殊处理的曲目及对应的流派/设置
      • 分两次处理：大多数曲目使用主流派预设，例外曲目使用自定义设置
  4. 记录决策 — 在母带处理报告中记录流派选择，以便交接
单轨自定义工作流:
  • 先使用主流派预设处理所有曲目
  • 然后针对自定义曲目，再次调用 
    master_audio
    并使用不同流派，将重新处理后的输出覆盖 
    mastered/
    目录中的原版本

Step 2: Analyze Tracks

步骤2：分析曲目

analyze_audio(album_slug)
What to check:
  • Current LUFS (integrated)
  • True peak levels
  • Dynamic range
  • Consistency across album
Red flags:
  • Tracks vary by >2 dB LUFS (inconsistent album)
  • True peak >0.0 dBTP (clipping)
  • LUFS <-20 or >-8 (too quiet or too loud)
analyze_audio(album_slug)
检查内容:
  • 当前LUFS（集成响度）
  • 真实峰值
  • 动态范围
  • 整张专辑的一致性
警示信号:
  • 曲目间LUFS差异>2 dB（专辑一致性差）
  • 真实峰值>0.0 dBTP（削波）
  • LUFS<-20或>-8（响度太低或太高）

Step 2.5: Audio QC Gate

步骤2.5：音频质量控制关卡

Run technical QC before mastering to catch source issues, and after to verify mastered output:
undefined
在母带处理前运行技术质量控制以发现源文件问题，在处理后运行以验证输出结果：
undefined

Pre-mastering: check raw files

母带处理前：检查原始文件

qc_audio(album_slug, "")
qc_audio(album_slug, "")

Post-mastering: check mastered output

母带处理后：检查处理后的输出

qc_audio(album_slug, "mastered")

**7 checks**: mono compatibility, phase correlation, clipping, clicks/pops, silence, format validation, spectral balance.

**Blocking issues** (FAIL): Out-of-phase audio, clipping regions, internal silence gaps, wrong format/sample rate, major spectral holes. Fix these before proceeding.

**Warnings** (WARN): Weak mono fold, minor spectral imbalance, trailing silence. Note in mastering report but don't block.

Include QC verdicts in the mastering report handoff (see "Handoff to Release Director" section).
qc_audio(album_slug, "mastered")

**7项检查**: 单声道兼容性、相位相关性、削波、咔哒声/爆音、静音、格式验证、频谱平衡。

**阻塞问题**（FAIL）：相位偏移音频、削波区域、内部静音间隙、错误格式/采样率、严重频谱缺失。处理前需修复这些问题。

**警告**（WARN）：单声道折叠效果差、轻微频谱不平衡、尾部静音。在母带处理报告中记录，但无需阻塞流程。

在交接给发布主管的母带处理报告中包含质量控制结论（请查看“交接给发布主管”部分）。

One-Call Pipeline (Recommended)

一键式流水线（推荐）

Use the 
master_album
MCP tool to run Steps 2–7 in a single call:
master_album(album_slug, genre="country", cut_highmid=-2.0)
This executes: analyze → pre-QC → master → verify → post-QC → update statuses. Stops on any failure and returns per-stage results. Use individual steps below only when manual intervention is needed between stages.
Note: 
master_album
applies one genre to all tracks. If Step 1.5 identified per-track genre overrides, use the manual step-by-step workflow instead — master the main batch first, then re-master override tracks individually with the different genre.
使用 
master_album
MCP工具一键运行步骤2–7：
master_album(album_slug, genre="country", cut_highmid=-2.0)
该工具会执行：分析 → 预处理质量控制 → 母带处理 → 验证 → 后处理质量控制 → 更新状态。若任何步骤失败则停止，并返回各阶段结果。仅当需要在阶段间手动干预时，才使用下方的单独步骤。
注意: 
master_album
对所有曲目应用同一流派。若步骤1.5中确定存在单轨流派自定义，请使用手动分步工作流 — 先处理主批次曲目，再单独重新处理自定义曲目并使用不同流派。

Step 3: Choose Settings

步骤3：选择设置

Standard (most cases):
master_audio(album_slug, cut_highmid=-2.0)
Genre-specific:
master_audio(album_slug, genre="country")
Reference-based (advanced):
master_with_reference(album_slug, reference_filename="reference.wav")
标准设置（大多数情况）:
master_audio(album_slug, cut_highmid=-2.0)
特定流派设置:
master_audio(album_slug, genre="country")
参考基准设置（进阶）:
master_with_reference(album_slug, reference_filename="reference.wav")

Step 4: Dry Run (Preview)

步骤4：试运行（预览）

master_audio(album_slug, cut_highmid=-2.0, dry_run=True)
Shows what will happen without modifying files.
master_audio(album_slug, cut_highmid=-2.0, dry_run=True)
展示将执行的操作，但不会修改文件。

Step 5: Master

步骤5：母带处理

master_audio(album_slug, cut_highmid=-2.0)
Creates 
mastered/
subdirectory in audio folder with processed files.
master_audio(album_slug, cut_highmid=-2.0)
在音频文件夹中创建 
mastered/
子目录，存放处理后的文件。

Step 6: Verify

步骤6：验证

undefined
undefined

Analyze the mastered output

分析处理后的输出

analyze_audio(album_slug, subfolder="mastered")

**Quality check**:
- All tracks -14 LUFS ± 0.5 dB
- True peak < -1.0 dBTP
- No clipping
- Album consistency < 1 dB range
analyze_audio(album_slug, subfolder="mastered")

**质量检查**:
- 所有曲目LUFS为-14 ± 0.5 dB
- 真实峰值 < -1.0 dBTP
- 无削波
- 专辑一致性差异 < 1 dB

Fix Outlier Tracks

修复异常曲目

If a track has excessive dynamic range and won't reach target LUFS:
fix_dynamic_track(album_slug, track_filename="05-problem-track.wav")
若某首曲目动态范围过大，无法达到目标LUFS：
fix_dynamic_track(album_slug, track_filename="05-problem-track.wav")

Step 6.5: Real-listener QC artifacts (
mastering_samples/
)

步骤6.5：真实听众质量控制 artifacts（
mastering_samples/
）

After verification, 
master_album
writes operator-listening artifacts to a sibling directory so 
mastered/
stays byte-identical to what gets uploaded to streaming platforms:
{audio_root}/.../[album]/
├── mastered/                         # Final masters — UPLOAD THIS
│   ├── 01-track.wav
│   └── ...
└── mastering_samples/                # Operator QA only — DO NOT UPLOAD
    ├── 01-track.aac.m4a              # 128 kbps AAC for Bluetooth listening
    ├── 01-track.mono.wav             # Mono fold-down sample
    └── 01-track.MONO_FOLD.md         # Per-band delta report + verdict
Two automated checks run here:
  • Codec preview — renders each master to 128 kbps AAC. Audition on AirPods / car Bluetooth before release; compressed playback exposes warbly sibilance, lost sub-bass, and pumping that the full-resolution master hides.
  • Mono fold-down — sums stereo to mono, measures per-band drops vs. stereo. A >6 dB drop in any band hard-fails the pipeline (phase cancellation). Listen to 
    .mono.wav
    on a phone speaker or single Echo to confirm which elements disappear in mono playback.
Standalone tools (run independently of the full pipeline):
render_codec_preview(album_slug)        # writes .aac.m4a files
mono_fold_check(album_slug)             # writes .MONO_FOLD.md + .mono.wav
Re-run cleanup (regenerable artifacts):
reset_mastering(album_slug, subfolders=["mastering_samples"], dry_run=False)
Configurable thresholds live in 
tools/mastering/genre-presets.yaml
under 
defaults:
(
mono_fold_band_drop_fail_db
, etc.) — override per-user in 
~/.bitwize-music/overrides/mastering-presets.yaml
.
验证完成后，
master_album
会将操作员监听用的artifacts写入同级目录，确保 
mastered/
目录中的文件与上传至流媒体平台的文件完全一致：
{audio_root}/.../[album]/
├── mastered/                         # 最终母带文件 — 上传此目录
│   ├── 01-track.wav
│   └── ...
└── mastering_samples/                # 仅用于操作员质量检查 — 请勿上传
    ├── 01-track.aac.m4a              # 128 kbps AAC格式，用于蓝牙设备收听
    ├── 01-track.mono.wav             # 单声道折叠样本
    └── 01-track.MONO_FOLD.md         # 各频段差异报告 + 结论
此处运行两项自动化检查:
  • 编码预览 — 将每个母带文件转换为128 kbps AAC格式。发布前在AirPods/车载蓝牙设备上试听；压缩播放会暴露全分辨率母带中隐藏的齿音失真、低音丢失和泵浦效应。
  • 单声道折叠检查 — 将立体声合并为单声道，测量各频段与立体声的差异。若任何频段差异>6 dB，流程将失败（相位抵消）。在手机扬声器或单个Echo设备上收听 
    .mono.wav
    文件，确认单声道播放时哪些元素消失。
独立工具（可脱离完整流水线运行）:
render_codec_preview(album_slug)        # 生成.aac.m4a文件
mono_fold_check(album_slug)             # 生成.MONO_FOLD.md + .mono.wav文件
重新生成清理（可恢复的artifacts）:
reset_mastering(album_slug, subfolders=["mastering_samples"], dry_run=False)
可配置阈值位于 
tools/mastering/genre-presets.yaml
的 
defaults:
部分（
mono_fold_band_drop_fail_db
等） — 可在 
~/.bitwize-music/overrides/mastering-presets.yaml
中按用户自定义。

Common Mistakes

常见错误

❌ Don't: Run Python scripts via bash

❌ 请勿：通过bash运行Python脚本

Wrong:
bash
python3 "$PLUGIN_DIR/tools/mastering/analyze_tracks.py" ~/audio/my-album
Right:
analyze_audio("my-album")
Why it matters: Bash hits system Python which lacks dependencies. MCP tools run inside the venv automatically.
错误做法:
bash
python3 "$PLUGIN_DIR/tools/mastering/analyze_tracks.py" ~/audio/my-album
正确做法:
analyze_audio("my-album")
原因: Bash调用系统Python，缺少依赖项。MCP工具会自动在虚拟环境中运行。

❌ Don't: Analyze originals after mastering

❌ 请勿：母带处理后分析原始文件

Wrong:
analyze_audio("my-album")  # Checks originals, not mastered output
Right:
analyze_audio("my-album", subfolder="mastered")
Why it matters: 
master_audio
creates a 
mastered/
subdirectory. Verify that output, not the originals.
错误做法:
analyze_audio("my-album")  # 检查原始文件，而非处理后的输出
正确做法:
analyze_audio("my-album", subfolder="mastered")
原因: 
master_audio
会创建 
mastered/
子目录。请验证该目录中的输出，而非原始文件。

❌ Don't: Skip the dry run

❌ 请勿：跳过试运行

Wrong:
master_audio("my-album", cut_highmid=-3.0)  # Writes files immediately
Right:
master_audio("my-album", cut_highmid=-3.0, dry_run=True)  # Preview first
master_audio("my-album", cut_highmid=-3.0)                 # Then commit
Why it matters: Dry run shows gain changes without writing files. Catches bad settings before they hit disk.
错误做法:
master_audio("my-album", cut_highmid=-3.0)  # 立即写入文件
正确做法:
master_audio("my-album", cut_highmid=-3.0, dry_run=True)  # 先预览
master_audio("my-album", cut_highmid=-3.0)                 # 再执行
原因: 试运行会展示增益变化，但不会写入文件。可在修改磁盘文件前发现错误设置。

Remember

注意事项

  1. Load override first - Call 
    load_override("mastering-presets.yaml")
    at invocation
  2. Apply custom presets - Use override genre settings if available
  3. -14 LUFS is the standard - works for all streaming platforms (unless override specifies different)
  4. Preserve dynamics - don't crush to hit target
  5. True peak < -1.0 dBTP - prevents clipping after encoding
  6. Album consistency - tracks within 1 dB LUFS range
  7. Genre informs targets - but streaming favors -14 across the board
  8. Master last - after all other editing/approval complete
  9. Test on multiple systems - not just studio headphones
  10. Tools are helpers - your ears are final judge
Your deliverable: Mastered WAV files at consistent loudness, optimized for streaming (with user preferences applied) → release-director handles release workflow.
  1. 优先加载自定义预设 - 调用开始时先调用 
    load_override("mastering-presets.yaml")
  2. 应用自定义预设 - 若存在自定义流派设置则使用
  3. -14 LUFS为标准 - 适用于所有流媒体平台（除非自定义预设指定其他值）
  4. 保留动态范围 - 不要为了达到目标而过度压缩
  5. 真实峰值< -1.0 dBTP - 防止编码后出现削波
  6. 专辑一致性 - 曲目间LUFS差异<1 dB
  7. 流派影响目标 - 但流媒体平台普遍偏好-14 LUFS
  8. 最后进行母带处理 - 在所有其他编辑/批准完成后
  9. 在多个系统上测试 - 不要仅使用专业监听耳机
  10. 工具仅作辅助 - 你的耳朵是最终判断标准
交付成果: 响度一致、针对流媒体优化的WAV母带文件（已应用用户偏好）→ 发布主管负责后续发布工作。
