๐Ÿ‘„ 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

๐Ÿ”ฌ 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.

๐Ÿ—ฃ๏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

๐Ÿ—บ๏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

๐Ÿง  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 ๐ŸŸ Flesh pink, natural positionTurns red = tongue root tension (like swallowing an egg)
Soft palate ๐ŸŸขGreen, moderately liftedToo low = heavy nasality (like talking with a cold)
Larynx ๐Ÿ”ตBlue, neutral positionToo high = tight sound; too low = muffled sound

Analogy

๐Ÿ  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.
