Good Voice Meter

Good Voice Meter is a real-time vocal tension analyzer. Sing or speak into your phone, and instantly see where your voice is pushing too hard.

WHAT IT DOES

Good Voice Meter listens to your microphone and shows three things:

A Pressure Score (0-100) that tells you how much tension your voice carries right now
Up to 3 Hotspot Frequencies where your voice is pushing hardest
A color-coded spectrum that highlights tension zones in yellow, orange, and red
Think of it as a thermal camera for your voice. Instead of showing raw audio data, Good Voice Meter interprets the spectrum and shows you what matters: where your voice is stuck, concentrated, or strained.

WHO IT'S FOR

Singers who want to see tension patterns during practice and warmups
Vocal coaches who need a visual aid to show students where they're pushing
Voice therapists looking for a simple, approachable tool for patients
Anyone curious about how their voice behaves under pressure
HOW IT WORKS

Good Voice Meter runs FFT-based spectral analysis focused on the vocal pressure region (800 Hz - 5 kHz). It tracks which frequencies persist over time, separating brief peaks from sustained tension. A frequency that spikes once is ignored. A resonance that sticks around gets flagged.

The pressure score combines prominence (how much a frequency sticks out), persistence (how long it stays), and spectral tilt (whether upper-mid energy dominates unnaturally). A relaxed voice scores low. A pressed or strained voice scores high.

No pitch detection. No recording. No audio leaves your device.

WHAT IT IS NOT

Good Voice Meter is not a tuner, not a recorder, and not a spectrum analyzer for engineers. It does not judge your singing. It does not detect pitch or tell you if you are sharp or flat. It shows you one thing: where your voice is working too hard. What you do with that information is up to you.

PRIVACY

Good Voice Meter uses your microphone for real-time analysis only. No audio is recorded, stored, or transmitted. All processing happens on your device.
