AI-assisted metadata cleanup for sound libraries
Turn rough filenames, missing descriptions, inconsistent keywords, and half-finished library metadata into something easier to search and reuse.
SFX Stacks uses your indexed library as context for metadata suggestions. It can suggest track titles, descriptions, UCS, and keywords from filenames, existing metadata, similar sounds, UCS data, audio analysis, duration, and your current edits. You review the results, adjust them, and decide what gets written.
Generate AI-assisted metadata suggestions, then review and apply only what you want to keep.
Why it matters
Large SFX libraries rarely stay clean. Vendor metadata, custom recordings, bounced design layers, renamed exports, and old folders all drift into different naming rules.
Bad metadata makes the same library harder to search, harder to reuse, and harder to move between tools. Metadata in SFX Stacks is built around fixing that practical problem, not generating text for its own sake.
What the AI helps with
AI-assisted suggestions can help draft:
- track titles
- descriptions
- UCS suggestions
- keywords
The suggestions are not final output. They are starting points for a review workflow, so you can apply what is useful and ignore what is not.
Edit and clean up in batches
Metadata work is not only AI suggestions. SFX Stacks also gives you direct editing tools for cleaning a selected set of files before writing changes.
Use it to review fields, apply suggestions, bulk apply repeated values, and search and replace text across draft metadata. This is useful for library-specific naming rules, creator/source values, repeated phrases, and keyword cleanup.
Write metadata back to the files
Approved changes are written as embedded audio metadata, not stored only inside SFX Stacks.
For WAV files, SFX Stacks writes common RIFF INFO and iXML / ASWG-style fields where supported. For other supported audio formats, it writes the closest common embedded metadata fields available through the file format.
The goal is to make cleaned-up metadata useful outside SFX Stacks too, in audio, library, and post-production tools that read compatible embedded metadata. Exact compatibility depends on the file format and how each application reads metadata.
Safer saving flow
Metadata changes stay as drafts until you save them.
Before writing metadata, SFX Stacks creates backup copies beside your audio files so you can recover the originals if needed.
Local-first by design
Metadata runs inside the same local SFX Stacks workflow as search, similarity, preview, and export.
Your audio files stay on your machine. The metadata suggestion model runs locally when installed. Your filenames, folder paths, metadata, embeddings, and library data are used for your own library workflow, not uploaded to train AI models or generate sounds.
Pricing during beta
During beta, Metadata is included with Pro. The active purchase path is SFX Stacks Pro.
After beta, Metadata is planned to become a separate module. Standalone purchase options will be shown when they are available.
