Prologue
How SonaLab Reads Your Voice
Open the app and you will see a wall of charts. Where do those numbers come from? — From your voice.
This page is the prerequisite primer for all SonaLab FAQ documents. You need no acoustics knowledge — just 10–15 minutes of hands-on play. We will start from "what is sound" and work our way to every line on the spectrum, and in the end you will discover: every number in the app is a part of your voice.
The Journey from Sound to Numbers
Your voice travels this pipeline to become the charts in the app. Each chapter on this page lights up one link of the chain. Try scrolling.

💡 Usage tips
- Sound is recommended (top-right button): every experiment lets you actually "hear" what you are dragging. Without it you still see the animations, but half the experience is missing.
- All values match the parameter meanings inside the app. Chart names in the text link to the chart gallery.
