Free · Designed for iPad. Not verified for macOS.

A free and open source voice analysis app specifically geared toward aiding speaking voice pitch and resonance training. The app is intended to be a useful tool for those who are already familiar with the concepts of pitch and resonance and how they affect the sound of speech. Features • Monitor the pitch of your voice live from your device's microphone. • Switch between multiple pitch estimation algorithms (Yin or IRAPT). • Enable formant estimation to analyze vocal resonance. • Pinch to zoom and pan around the pitch chart for a closer look. • Customize the visual guide lines to help stay within a certain pitch range. • Save recordings for later inspection and playback. • Play, analyze, export, share, rename, or delete saved recordings. • No ads or collection of data whatsoever. Recordings never leave the device unless explicitly shared to another app.
