๐ Acoustic View
The Acoustic View lets you "see through" your mouth. Where is the tongue? Is the larynx riding high? Is the soft palate lifted? Things you can never watch directly โ SonaLab visualizes them all.
Analogy
๐ฌ If the Engine View watches the "engine", the Acoustic View watches the "shape of the exhaust pipe". After leaving the vocal folds, sound travels through the throat, the mouth and the nose before it becomes what listeners hear. The shape of your vocal tract decides the "flavor" of your sound.
๐ฃ๏ธ Formant Tracking โ The Vowel Map
This is a "vowel map". Sing different vowels (ah, oh, ee, oo, eh) and the cursor moves to different spots on the map.
Analogy
๐บ๏ธ It works like a "GPS for your mouth". The white cursor is "where you are now"; the colored dots are "where the reference vowels live". The closer the cursor sits to a dot, the closer your sound is to that vowel.
How to use it:
- On "ah", the cursor should sit low on the map (jaw dropped wide)
- On "ee", the cursor should sit toward the top right (wide mouth, tongue forward)
- If the cursor keeps drifting away from the target vowel, your mouth shape or tongue position needs adjusting
๐ง Sagittal View โ The "X-Ray" of Your Vocal Tract
The Sagittal View is one of SonaLab's coolest features. It renders a live side view of your head, showing what's happening inside your mouth in real time as you sing.
Three key structures move dynamically in the view:
| Tongue ๐ | Flesh pink, natural position | Turns red = tongue root tension (like swallowing an egg) |
| Soft palate ๐ข | Green, moderately lifted | Too low = heavy nasality (like talking with a cold) |
| Larynx ๐ต | Blue, neutral position | Too high = tight sound; too low = muffled sound |
Analogy
๐ Picture your mouth as a room. The tongue is the floor, the hard palate is the ceiling, the soft palate is the curtain at the back, and the larynx is the entrance to the basement. The shape of the room decides the "echo" your voice gets.
Tip
If the tongue turns red while you sing, the tongue root is gripping. Try sticking your tongue out and singing "lah" to let it relax.
