Use Your Ear vs Tone Scope Lab

The 9 pivot points: · **50 Hz** — Depth & Weight · **100 Hz** — Warmth & Punch · **200 Hz** — Thickness & Mud · **500 Hz** — Boxy & Gargle · **1 kHz** — Nasal & Knock · **2 kHz** — Edge & Clarity · **5 kHz** — Presence & Bite · **10 kHz** — Sizzle & Snap · **20 kHz** — Air & Plastic Each pivot mapped to perceptual adjectives — so you don't just memorize numbers, you learn what they SOUND like. Four training modes: EQ Workbench — Interactive 9-band parametric. Drag nodes vertically for gain, scroll wheel for Q, double-click to reset. Frequencies are locked to the pivot points (that's the whole point). Quiz — Blind pivot trainer. The app boosts or cuts a random pivot on pink noise at Easy / Medium / Hard difficulty. A/B between processed and bypass, then pick the frequency + direction. Scoring tracks your accuracy over time. Listen — A/B reference mode. Set gain and Q on a single pivot, toggle A/B against bypass, and read the "Boost to..." / "Cut to..." cheat sheet. Train your ear by hearing the same EQ move at multiple frequencies. Sweep — Manual sine tone across the spectrum, plus an automatic logarithmic sweep from 20 Hz to 20 kHz with the nearest-pivot readout. Hear the spectrum, build the mental map. Sources: · Pink noise (Paul Kellet generator, 4-second loopable buffer) · Sine tone · Log sweep · Your own audio file · Live microphone (with feedback warning) Hearing safety built in: Three independent ways to instantly stop audio: 1. Mute button — instant silence, playback can resume 2. Stop button — tears down the audio source completely 3. Always: keep your master volume LOW, use headphones at safe levels Sine tones and sweeps are internally attenuated to 15% of full scale. Why is it free?

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.
