Step 1: Open SonaLab and Allow Microphone Access

On first launch, the system will ask whether to allow microphone access. Click "Allow".

If you're using an external mic or audio interface, click the 🎙 microphone button in the top-right corner and select your device.

Step 2: Click "Start Measuring"

Click the ▶ Start Measuring button in the toolbar. Speak or sing into your mic and the charts on screen start moving.

Like an EKG — you make sound, it responds.

Step 3: Sing an "Ah" and Watch What Changes

Sing a long, comfortable "Ah~" at an easy volume. You'll see:

• the waveform rise and fall (the shape of your sound)
• pitch display the note you're singing
• the TA/CT Balance show the "thickness" of your voice
