Singing tips
🎤
Switch to microphone mode and sing — you'll see your voice's fundamental pitch and the harmonics above it.
💡
Singing teachers use spectrograms to show students how vowel placement affects the harmonic spectrum. Try saying "ee" then "ah" — the formants visibly shift.
🎯
For vocal training: watch how high you can take a note. Most untrained voices peak around C5-G5. Trained singers extend higher.
🎨
For a fun demo: whistle, hum, and speak in front of the analyzer — each produces dramatically different spectrum patterns.
