About Tone Scope Lab
Tone Scope Lab is a real-time tuner and spectrum analysis tool designed for musicians who want to see pitch, not just read a number. At the center of Tone Scope Lab is its infinite circular pitch ruler, which provides a continuous visual view of pitch movement while you play. Real-time spectrum visualization lets you see the frequency components of your instrument’s sound, providing another visual perspective alongside the pitch ruler. The Transpose Ruler provides a quick visual reference for transposing instruments, helping you relate written and sounding pitches at a glance. Choose from three generations of analysis and display systems: • Gen-1 — a simple and direct tuning view • Gen-2 — enhanced analysis and visualization • Gen-3 — the latest generation, combining multiple stages of analysis for more focused pitch detection Tone Scope Lab also supports instrument presets. The built-in General preset provides flexible, all-purpose tuning, while additional instrument presets can be downloaded for more focused analysis ranges. Features: • Real-time pitch detection • Infinite circular pitch ruler • Real-time spectrum visualization • Transpose Ruler for transposing instruments • Frequency display • Three generations of analysis and display • Instrument presets • Downloadable additional presets • Adjustable spectrum display modes • Designed for instrument practice, tuning, and sound observation Tone Scope Lab is designed to make pitch behavior visible — from a simple tuning reference to a deeper view of how your instrument’s sound behaves.
