Use Your Ear vs Aux Control

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? Tomorrow's working sound engineers are today's audio students. We want you to learn properly — not paywalled, not gated, not crippled. No ads. No data harvesting. Just a real tool.

Aux Control is a party music jukebox for bars, cafes, and events. The host runs the iOS app on their iPhone, which connects to Apple Music and starts a room. Guests join by scanning a QR code or entering a room code at auxcontrol.live in any browser — no app download required. Guests set a screen name and vote on which song plays next. The host controls playback and manages the guest list. BUILT FOR REAL PARTIES • Works best with 5+ people — house parties, bars, weddings, DJs fielding requests, all of it • Sessions self-destruct after 24 hours — zero cleanup • Skip is host-first, always — you're never at the mercy of the crowd • Kick a guest, yeet a queued track, or seed the first song yourself before votes even start • Turn voting off for a simple first-come, first-served queue — great for smaller crews who'd rather skip the ballot PARTY PASS Free sessions cap at 8 people. Party Pass is an auto-renewing annual subscription that bumps the cap to 150 guests — built for the bigger stuff: weddings, blowouts, hosts running it all year. Renews automatically each year unless you cancel at least 24 hours before renewal; manage or cancel anytime in Settings > Apple ID > Subscriptions.
