Tone Scope Lab
Real-Time Tuner & Spectrum
Free · Designed for iPad. Not verified for macOS.
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.
