Digital Vocal Coach

Sing into your microphone, watch your pitch move in real time, generate one or several target tones or exact frequencies, and see how your voice relates to the primary reference harmonically.

0 / 8

Add the current frequency to layer it with the primary target tone.

0 Hz is silence rather than an audible pitch. Frequencies below about 20 Hz are generally sub-audible and may not be reproduced by ordinary speakers or headphones. Multiple tones are automatically gain-balanced to reduce clipping.

Saved frequencies

These preset names are user-defined labels, not medical claims. The app does not establish that these frequencies cause healing, regeneration, or stem-cell effects.

Harmony relationship

Sing + play a target

This compares your detected pitch with the currently selected reference frequency, octave-equivalent.
