Symptoms & Pitch

(((CHART LIBRARY)))

30 Acoustic Charts, Beginner to Expert

From free basics to expert AI analysis. Unlock as you grow.

Warm-Up / Cool Down

Guided vocal recovery session with three SOVT exercises for warming up before singing or cooling down after practice.

Vocal Health Score

Provides a comprehensive assessment of your overall phonation quality, calculating a score from 0–100 based on multiple parameters.

Symptom Detection

Detects multiple common vocal symptoms in real time, helping you identify and improve your phonation habits.

Pitch Detection

Displays the current fundamental frequency (Hz) and corresponding note name in real time, helping you accurately identify your pitch position.

Pitch Recording

Real-time pitch history line chart recording your singing trajectory with snap and real pitch modes.

Resonance Depth Detection

Evaluates the resonance depth of your voice, reflecting larynx position and pharyngeal resonance.

Vocal Fold Closure

Displays the degree and type of vocal fold closure, helping you find an efficient and healthy phonation approach.

TA/CT Balance

Displays the current vocal fold thickness during phonation, reflecting the balance between TA (thyroarytenoid, thickens folds) and CT (cricothyroid, thins folds) function.

Singer's Formant Monitor

Displays the projection ability and carrying power of your voice, reflecting the concentration of high-frequency energy. Closely related to the singer's formant.

Larynx Position

Displays the vertical position of the larynx in the neck. Larynx position affects vocal tract length and vocal timbre.

Waveform

Displays the amplitude variation of the audio signal in the time domain. The X-axis represents time and the Y-axis represents amplitude intensity.

Loudness Meter

LUFS (Loudness Units relative to Full Scale) is a perceptual loudness unit based on human hearing, following the ITU-R BS.1770 international standard.

Onset Detection

Detects the onset type at the beginning of phonation. Onset type has a significant impact on vocal fold health and voice quality.

Sound Science
