App Description
Voice Bias is a real-time vocal tension analyzer. Sing or speak into your iPhone, and instantly see where your voice is pushing too hard.
WHAT IT DOES
Voice Bias 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, Voice Bias 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
Voice Bias 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.
KEY FEATURES
- Real-time pressure score with smooth attack/release
- Persistent hotspot detection that ignores transients
- Live spectrum display with heat-map highlighting
- Works in portrait and landscape
- Zero configuration -- just open and sing
- Low CPU usage, 60 FPS display
- No account required, no data collected
WHAT IT IS NOT
Voice Bias 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
Voice Bias uses your microphone for real-time analysis only. No audio is recorded, stored, or transmitted. All processing happens on your device.
