Use Your Ear vs SoundCoach

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.

Running sound at your church or small events without formal training? SoundCoach is the assistant standing next to you at the console. MEASURE IN REAL TIME • Decibel meter (dB SPL) with session history and color zones, so you know when volume is safe and comfortable. • Full-screen 31-band spectrum analyzer (RTA): see exactly which frequencies dominate your mix. • Feedback detector: an alert tells you which frequency is taking off before the squeal ruins the moment. DESCRIBE THE PROBLEM IN YOUR OWN WORDS "Sounds boxy", "too metallic", "can't understand the vocals", "it booms". No technical vocabulary needed — pick tags or write it the way you hear it. GET CONCRETE ADJUSTMENTS AI combines your description with the real analysis of your room's sound and gives you prioritized steps: which frequency to EQ (with exact gain and Q), how to set the compressor or gate, and what to do with effects. Every adjustment comes with a plain-language explanation of what will improve. PRIVACY FIRST Audio never leaves your phone. All sound processing happens on your device; only numeric analysis data goes to the cloud. No sign-up, no accounts, no personal data. BUILT FOR VOLUNTEERS SoundCoach was born for sound operators at churches and small events: people who serve with heart and learn on the go. Measurements are approximate (iPhone mics aren't calibrated instruments), but more than enough to make better mixing decisions. The free tier includes the meter, the spectrum analyzer, the feedback detector, and a limited number of AI recommendations per month.
