Use Your Ear vs Plotwright

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?

Plotwright builds the two documents every gig needs — a stage plot and an input list — and turns them into one clean, print-ready PDF you hand to the venue's sound engineer. Pay once. No subscription, no account, no WiFi required. It's made for the band member who got volunteered to "make the tech rider" and the front-of-house engineer who has to read it in dim light at load-in. What you build on screen is exactly what prints — no fuzzy export, no surprises at soundcheck. WHAT YOU GET • A top-down stage plot you build by dropping in simple, map-like symbols for the gear on stage — like drums, amps, monitors, DIs, and risers. Move, resize, rotate, rename, or duplicate anything. • An input list that numbers itself in the order engineers expect — kick, snare, toms, overheads, bass, guitars, keys, vocals — so you look like you know the convention even if you don't. Reorder by hand any time. • One-page output with the plot and the numbered input list on the same sheet. • A true-vector PDF that stays sharp and reads cleanly in black and white — because it's getting printed and folded into someone's back pocket. BUILT THE WAY THE SHOW ACTUALLY RUNS • Stage orientation is fixed and labeled — audience at the bottom, stage left and stage right from the performer's point of view — so no one patches the stage backwards. • Your act name, contact, and the date it was last edited are burned into the PDF, so the engineer always knows whose plot it is and how current it is. • Everything stays on your device. No cloud, no sign-in, nothing to sync. FREE TO BUILD, ONE-TIME UNLOCK TO EXPORT Build your plot, add your gear, and preview the finished page for free. A single one-time purchase unlocks PDF export, save, and share — for good. No subscription. No paywall in your way while you work. Made for gigging musicians, bands, and the live-sound engineers who advance their shows.
