Recognition is an import-and-correct workflow; it is not advertised as universally perfect.

Workflow

How this path works

The public page leads into the authenticated app workflow when users are ready to process a score.

Upload a PDF or image

The app stores the source and creates an OMR import job tied to a score project.

Run Audiveris recognition

When configured, the worker calls Audiveris, stores the generated MusicXML, and creates an editable candidate revision.

Correct the candidate

Review diagnostics, preview the score, fix recognition mistakes, then export or generate practice materials.

Product detail

What to expect

Candidate-first recognition

OMR results are treated as editable candidates with confidence and diagnostics, not as guaranteed final scores.

Production wiring still matters

Audiveris installation, command configuration, timeout tuning, and deployment packaging must be handled for production.

FAQ

Questions about PDF score scanner and OMR

Practical limits and expected workflow for this score tool.

What input does PDF score scanner and OMR accept?

The app stores the source and creates an OMR import job tied to a score project.

Can I edit the result after conversion?

Yes. Successful imports become Score JSON revisions that can be corrected, transposed, played, and exported from the score workspace.

What should I check before relying on the result?

Scanning is import plus correction. The site should not promise perfect automatic recognition for all PDFs or photos.
