A score becomes useful when you know which file was analyzed, by which engine and on what date. Demorphus brings that information together in a report you can keep.

Read the score and verdict together

Demorphus displays the AI score returned by SH Labs, on a scale from 0 to 100. It also shows the engine’s classification label when available. We preserve that label instead of inventing a verdict from a threshold selected by Demorphus.

The number is a model output. Demorphus does not interpret it as the share of a track made with AI: a score of 60% does not mean that 60% of its notes, stems or running time are artificial.

Why keep the date and model version?

Your report identifies the export by its filename and SHA-256 fingerprint. The date records when the analysis happened; the model version appears if SH Labs provides it. These fields help distinguish two files or two analyses.

On Demorphus, uploading the same file from the same session can reuse its result for 24 hours. The site labels that reuse and keeps the original date. It does not present a reused result as a fresh analysis.

Does a low result guarantee human authorship?

We do not turn a low score into a certificate of human authorship. Music detection research highlights challenges involving audio transformations and previously unseen generators. Afchar, Meseguer-Brocal and Hennequin discuss these general limitations; their paper does not measure SH Labs performance. AI-Generated Music Detection and its Challenges ↗

How do you compare an original and an export?

  1. Keep your original and give each export a distinct filename.
  2. Analyze each file separately, keeping the duration and musical content comparable.
  3. Save the reports and note the score, verdict, date and model version.
  4. Listen to both files at comparable playback levels before choosing which to use.

This comparison describes those specific files. To evaluate a tool, repeat it across several tracks whose creation process you know. An isolated result cannot support a promise about an entire catalog.
