## Description

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

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.
