What it measures
Frequency in Hz shows how fast your voice is vibrating. Musical note shows the closest note name, such as A3 or C4. Cents show how close your pitch is to the nearest note.
Lowest, highest, and average pitch summarize stable readings from your current session. This tool is for general pitch reference only and is not a substitute for guidance from a vocal coach, clinician, or other qualified professional.
