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.
