11月2日 的 Piano Tuner - Pro Tuning 應用程式分析

Piano Tuner helps piano technicians measure inharmonicity, build custom stretch curves, and follow pitch in real time. Move from initial measurements through fine tuning, then save each piano's setup for your next visit. REAL-TIME TUNING Work across all 88 keys from A0 to C8. Use automatic note detection, manual selection or note lock. Read pitch deviation in cents alongside phase and spectrum displays. STRETCH CURVES FOR EACH PIANO Measure multiple notes to analyze the piano's inharmonicity and generate its stretch curve. Adjust the bass, middle and treble regions, or fine-tune individual note targets. PITCH PREMEASUREMENT AND FINE TUNING Premeasure the piano and record its current pitch deviations, then use the final tuning curve for fine tuning. This version supports premeasurement; overpull compensation and coarse tuning are not yet available. MULTI-PARTIAL ANALYSIS AND TEMPERAMENTS View pitch deviation for up to four partials at once, with a phase display for the selected partial. Adjust the A4 reference frequency, choose historical temperaments or create a custom temperament. TUNING FILES Save measurements, curves and notes for each piano. Reopen a saved setup for future work. Import and export tuning files through the Files app for backup and sharing. REFERENCE TONES AND INPUT CALIBRATION Play reference tones for note targets or selected partials. Calibrate the current audio input using an external reference with a known frequency. BUILT FOR IPHONE AND IPAD Use portrait or landscape layouts with light and dark modes. Audio is analyzed on your device, and tuning files are stored locally. Core tuning features work offline, with no account required. FREE EVALUATION. ONE-TIME PRO UNLOCK.
