How it works

By Friday, you'll feel it. By month two, they will.

You stop guessing. You stop second-guessing. Each morning Sound shows you the one move that matters most this week — and that's the only thing you do. The change happens before you notice it. The room notices later.

Once a week

Sing into your phone. See what the ear can't.

Thirty seconds, once a week. The Voice Check turns your harmonics, breath, vibrato, and placement into a thermal portrait. The same picture vocal coaches use when they want to show a singer what's actually happening.

Stacked harmonics
Bright orange bands stacked at multiples of the fundamental — the sign of a well-supported tone.
Singer's formant
The 2.5–3.5 kHz band brightens when you find the resonance that lets your voice carry.
Vibrato shimmer
The pulsing dots are vibrato cycles — Sound counts them and reads the rate.
