A CREATION OG PERCEPTION EXPERIENCE
Shape
your sound.
One note.
Many ways to hear it.
Discover what changes a sound’s character.
Then make a sound of your own.
Listen to the difference.
Choose a shape for the sound. The base note stays the same.
These are synthesized vowel-like examples, not recordings of a human voice. Choose a preset, then listen.
Notice what stands out.
One sound contains many frequencies. Some are stronger than others.
Calculated components of the model, before playback. Taller bars mean stronger components. This is a graph of sound, not a picture of a mouth.
What changed: the note, the character of the sound, or both?
Make it your own.
Move the emphasis. Listen again. Follow what catches your ear.
Sound is off. Listen, then move either slider.
Each control moves a broad band of emphasis across the sound’s harmonics. The pitch source remains 216 Hz. These controls model resonance; they do not reproduce your mouth’s exact shape.
A recipe saves your settings as a small file. It does not record audio or upload anything.
Try your own voice
Gently hold a comfortable note and move from “ah” toward “ee.” Notice how the frequency pattern changes. You can also keep exploring with the examples above.
Microphone access is optional. Sound is analyzed only in this page, never recorded, played back, or uploaded. The microphone stops after 30 seconds, when you leave this page, or when you choose Stop.
You help give it form.
First you noticed a relationship. Then you changed it. What did you discover—or create—that you want to hear again?
Your reflection stays in this page only. It is not submitted or saved with your recipe.
What is happening in this experience?
In voiced speech, vibrating vocal folds provide a source. The throat, mouth, tongue, and lips help shape which frequencies reach a listener strongly. This simplified example starts with harmonics of 216 Hz and changes their relative strength.
The “ah,” “oh,” and “ee” settings are illustrative models. Actual voices vary with the person, language, accent, pitch, and delivery. There is no single universal frequency for a vowel.
While a generated sound plays, the graph shows its live audio spectrum. When stopped, it shows the calculated components of the current model. In microphone mode, it shows the incoming microphone signal. Rooms, microphones, and device processing affect that display.
The 432 Hz tuning reference sets the musical base note. Higher harmonics extend above it; they help create the sound’s character. The graph does not measure a person’s inner state or identify a spiritual quality.
