Voice Pitch & Range Analyzer

Knowledge Base

How Pitch Detection Works Here

This tool uses autocorrelation, comparing your voice's waveform against a time-shifted copy of itself to find the delay (lag) where they match most closely. That lag directly corresponds to the period of your voice's fundamental frequency, which converts to pitch and then to the nearest musical note. Unlike a simple frequency-domain peak (which can be confused by harmonics), autocorrelation reliably tracks the true fundamental of a sung or spoken note.

Using This for Range Testing

Sing or speak comfortably across your full range, from your lowest chest voice note to your highest falsetto or head voice note, while watching the range bar build. This is a practical, informal range check. A vocal coach's assessment considers tone quality and comfort at the extremes too, not just raw pitch reached.

Useful For

• Voice actors checking their natural speaking pitch range for casting notes.
• Singers warming up and tracking range expansion over time.
• Anyone curious what note their speaking voice naturally sits at.

FAQ

Q: Why does the note jump around on sustained notes sometimes?
A: Natural vibrato, breath noise, or background sound can all cause brief detection jitter. A steady, sustained tone in a quiet room gives the cleanest reading.

Q: Does this work for detecting pitch in music, not just voice?
A: It works on any single melodic line with a clear fundamental frequency, but is tuned and tested primarily for the vocal range, polyphonic (multiple notes at once) audio will not track reliably.
