What the analyzer measures
The tool uses the Web Audio API and an autocorrelation pitch detector to estimate fundamental frequency from short microphone samples. The displayed statistics summarize accepted samples; they are not a laboratory measurement. Background noise, microphone processing, vocal fry and harmonics can change the estimate.
How to interpret the result
Pitch is one part of a voice. These measurements cannot establish gender, attractiveness, health or personal worth. Labels and reference bands are simplified guides, not validated diagnoses or population rankings. Do not strain your voice to reach a target; persistent pain or voice changes need advice from a qualified clinician.
