Ivory Pro is a professional hybrid DSP piano tuner for macOS, iOS, and iPadOS. Featuring Railsback stretch tuning curves, tailored physical instrument profiles, and sub-cent precision.
Ditch the generic chromatic tuners. Harness an audio-engineering pipeline designed specifically for the unique physical properties of pianos.
Plug-and-play for Focusrite Scarlett, ZOOM iQ7, and any class-compliant USB audio device. Live mic info shows device name, sample rate, and channels. Adjustable 1×–10× software gain ensures optimal signal from professional interfaces.
Calculates real-time, inharmonicity-aware Railsback stretch curves to flatter the bass register and add brilliant sparkle to high-end chords.
Dedicated physical presets for Concert Grands, Uprights, Electric Pianos (Rhodes/Wurli), and Spinets/Honky Tonk pianos.
Direct manual control over physical needle response damping, response speeds, noise gate, and FFT smoothing window sizes.
Employs McLeod Pitch Method (NSDF) with sub-harmonic filtering for low keys (A0-B0) and linear-magnitude FFT interpolation for C8.
Synthesizes mechanical, wooden mechanical box click soundscapes alongside classic, high-fidelity visual pendulum physics.
A stunning, glassmorphic dark-mode environment optimized for dimly-lit studios, stages, and piano soundboard compartments.
Low frequencies in a piano are highly transient and have extremely weak fundamental frequencies, whereas high frequencies are short and decay rapidly. Traditional tuners fail at both extremes. Ivory Pro handles them with state-of-the-art DSP:
vvsqrt), treble tracking errors are mathematically resolved.Automated real-time handoff between NSDF and linear-interpolated FFT based on frequency thresholds.
