Method

Auto chooses the notes. Manual lets you refine the detection.

Adaptive parameter search (independent thresholds and refinement; uncheck both optimization boxes for original Auto) Improved A/B/C selection (compare note durations and cleaned results; uncheck for original selection) Generate Enhanced transcription (experimental; also generates Hybrid with waveform-first discovery; slower and uses more memory; A/B/C unchanged) Also generate Vocal Ensemble (experimental joint polyphonic vocal pitch search at shared chord attacks; requires Enhanced; A/B/C, Enhanced and Hybrid unchanged)

Score versionsCompare different note detections

Enhanced uses independent acoustic analysis. It has no single Manual parameter profile; switch to A/B/C before choosing Adjust in Manual.

A is the leading interpretation. Alternatives appear only when the detected notes differ meaningfully.

Improve score Smooth octave jumps Group close attacks

Fine-tune

Attack grouping range 25%

Lower keeps more separate notes. Higher joins more starts.

Octaves shift only when the audio supports a smoother phrase. Chords are protected.

Corrections will apply to your score.

Review octave decisions

Correct an extra note in a chord

No timing changes applied.

No automatic decay corrections applied.

Choose a detected chord, then select just the false pitch. This changes notation, playback, JSON and MIDI exports without changing the transcription algorithm. Undo restores the previous score. Corrections are lost if you re-transcribe.

Only events containing more than one pitch appear here.
