Pitch Witch

iOS Universel / Utilitaires

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.
