Review and Correct Detected Notes

Check a music transcription against the original recording before you turn it into sheet music, MIDI, or a visualization.

Supported formats: MP3, WAV, FLAC, M4A, AAC, OGG (Max: 50MB)

What you get

  • Start note analysis when you are ready; it runs separately from the initial audio upload and processing.
  • Review suspicious notes suggested by deterministic musical diagnostics, or switch to All notes for a complete manual check.
  • Audition the original source around a note, then keep it, change its pitch or octave, or delete a false detection.
  • Some notes may remain unscored: not every transcription system provides calibrated per-note confidence, and an unscored note is not automatically suspicious.
  • Corrections are saved as versioned transcription revisions, so the original analysis remains available for comparison or restoration.

How it works

  1. 1 Upload an audio file from your computer or phone.
  2. 2 The AI analyzes tempo, key, and instrumentation, separating stems when needed.
  3. 3 Processing runs in the background — you can watch the progress live.
  4. 4 Use the reviewed transcription to export MIDI or generate sheet music and compatible visualizations.

Frequently Asked Questions

It helps you check quiet, ambiguous, or octave-shifted notes against the source recording before relying on a generated score or MIDI file.

No. Some transcription systems do not provide calibrated per-note confidence. The review workflow keeps those notes explicitly unscored and uses separate deterministic musical diagnostics where the available data supports them.

Yes. Suspicious notes are the focused starting queue, and All notes lets you inspect the complete canonical transcription manually.
