Manifold ~ Audio Batch Processing Tool


Manifold is a desktop audio batch-processing tool built for inspecting, transforming, and exporting large collections of audio files with a visual workflow editor. Useful for checking and pre-processing audio for game-audio production, podcasts and broadcast, it is designed to make repetitive tasks more efficient and reproducible.

It combines a polished ImGui-based interface with a custom node-based audio pipeline, allowing you to build repeatable processing chains for tasks such as loudness normalization, peak limiting, DC offset cleanup, resampling, and format conversion.Why Manifold?

Manifold was designed to make audio batch work feel more structured and reproducible. Instead of manually running ad-hoc commands or scripting every step, you can:

  • import whole folders of audio files,
  • inspect their metadata and analysis results,
  • create reusable processing chains,
  • export processed files with consistent naming and format settings.

This makes it useful for workflows such as podcast preparation, mastering prep, broadcast delivery, and game-audio asset processing.

Key Features:

  • Batch import of files and folders
  • Drag-and-drop support from the file explorer
  • Built-in audio playback for quick previews
  • File table with metadata and analysis metrics
  • Configurable processing workflows using nodes
  • Output settings for folder, naming, format, and subtype
  • Background processing with task history and logs
  • Parallel analysis for loudness and DC offset metrics

Supported Processing Nodes:

Manifold includes a growing set of audio processing and analysis nodes, including:

  • Loudness analysis
  • Loudness normalization
  • True peak limiting
  • DC offset removal
  • Peak normalization
  • Channel mixing
  • Silence trimming
  • Fade in/out
  • Loudness compliance checks
  • Clipping detection
  • Dynamic range analysis

These nodes can be chained together to create custom pipelines for different production scenarios.

foobar2000 ~ foo_filename_editor


Advanced file renamer component for foobar2000 media player. This plugin helps you rename your physical audio files on your hard drive based on their metadata tags, while ensuring a seamless, smart, and fully automated workflow.

Key Features:

  • Smart Track Number Padding: Automatically scans all selected tracks. If the album contains 100 or more tracks, it pads numbers to 3 digits (001, 002), otherwise it defaults to 2 digits (01, 02) dynamically.
  • Intelligent Compilation (Various Artists) Detection: Automatically checks %album artist% and %artist% tags. If it detects a compilation, it seamlessly applies your custom VA formatting template.
  • Advanced Case Conversion: Supports Title Case, Smart Title Case (keeps short words like a, an, the, and, with lowercase), Sentence case, ALL CAPS, and lowercase.
  • Roman Numerals Preservation: Intelligently detects standalone Roman numerals (e.g., Part iii) and forces them to uppercase (Part III) across all case conversion modes (except lowercase). Includes protection against false positives (words like MIX, DIV).
  • Extended Unicode & Ligature Support: Works perfectly with Windows native APIs, preserving and processing complex characters like æ, œ, ß, and language-specific diacritics.
  • Safe Formatting Menu: Quick insertion menu for popular tags and safely escaped syntax characters like '(', ')', '[', ']', and single/double quotes (', '').
  • Seamless Playlist Synchronization & Reload: Automatically replaces dead file links in all open playlists with the newly renamed paths. Instantly reloads file tags and durations in the background—no broken links, no manual reloading required!
  • Robust Error Handling: If a file cannot be renamed (e.g., if it is locked or currently playing), the plugin bypasses it without crashing and provides a detailed summary report of successful and failed files.
  • Persistent Settings: Remembers your custom single/VA templates, history list, checkboxes status, and even your preferred window column widths between sessions.

🎵 M3U/M3U8 Playlist Generation (v1.1)

The plugin now includes built-in support for generating playlist files automatically during the renaming process:

  • Save M3U Checkbox: Automatically creates a playlist file in the top-level directory of your processed files.
  • Custom Naming Templates: Use standard foobar2000 title formatting syntax (like %album% or %artist% - %album%) to dynamically name your playlist file.
  • EXTINF Metadata: Optional toggle to write standard #EXTM3U and #EXTINF headers containing track durations and formatted titles (%artist% - %title%).
  • Smart Conflict Resolution & Overwrite Toggle: Prevents accidental loss of data. If overwrite is disabled, the plugin safely creates incremented filenames like Playlist (1).m3u.
  • UTF-8 Compatibility: Playlists are written with a proper UTF-8 BOM, ensuring seamless support for non-ASCII characters, symbols, and ligatures.
