How accurate is the pitch detector?

Our tool is highly accurate, with a precision of within ±5 cents of a note. It uses the industry-standard YIN algorithm for reliable, real-time analysis suitable for both musicians and audio professionals. For more details, see our accuracy tests .

Is my audio data private and secure?

Absolutely. Your privacy is our top priority. All audio processing is done locally in your browser. No audio is ever recorded, stored, or sent to a server. You can read our full data security policy for more information.

The detector isn't working. What should I do?

First, ensure you have granted microphone access in your browser. If it's still not working, try using a quiet, echo-free environment and holding a clear, steady note. For a complete list of solutions, please visit our troubleshooting page .

What are 'cents' in music?

A 'cent' is a unit of measurement for musical intervals. There are 100 cents in one semitone (the distance between two adjacent notes on a piano). Our meter shows how many cents sharp (positive value) or flat (negative value) your note is, allowing for very precise tuning.

What is the difference between pitch and frequency?

Frequency is the scientific measurement of a sound wave's vibrations per second, measured in Hertz (Hz). Pitch is the musical term for how high or low a note sounds to our ears. While they are related, pitch is a subjective perception, whereas frequency is an objective measurement. Learn more in our glossary .

Can I use this to tune my guitar?

Yes! This tool works perfectly as an online guitar tuner. Simply play each string one at a time and use the feedback to adjust the tuning pegs until the note is perfect. It works for acoustic and electric guitars (if played through an amplifier).

Voice Pitch Analyzer: What It Is & How to Use It for Singing Practice

Whether you’re a beginner singer or a vocal coach, a Voice Pitch Analyzer is one of the most useful tools you can add to your training. It helps you understand your pitch accuracy in real time, showing whether you’re singing flat, sharp, or in tune.

This article explains what a Voice Pitch Analyzer is, how it works, and step-by-step tips to improve your singing accuracy.

What Is a Voice Pitch Analyzer?

A Voice Pitch Analyzer is a browser-based tool that listens to your singing and displays:

Musical note name (e.g., A4, C#3)
Frequency in Hz (e.g., A4 = 440 Hz)
±Cents deviation (how close you are to the correct pitch)

Unlike a simple tuner, it provides real-time visual feedback so you can see how steady your pitch is while practicing.

You can try the free Voice Pitch Analyzer right now — no downloads or sign-ups required.

How It Works: Simple Explanation

The microphone captures your voice.
The analyzer detects the fundamental frequency of each note.
It shows your note name, pitch stability, and ±cents deviation on-screen.

All processing happens in your browser for privacy and low latency. See our Methodology page for the technical details.

Benefits for Singers & Coaches

Real-time feedback: See instantly if you’re flat, sharp, or in tune.
Improves ear training: Helps singers connect what they hear with what they sing.
Builds pitch stability: Use ±cents readings to hold steady notes.
Supports vocal warm-ups: Perfect for scales, intervals, and vowel training.

Step-by-Step: How to Use the Voice Pitch Analyzer

Open the Tool: Voice Pitch Analyzer
Allow Microphone Access: Grant permission when the browser asks.
Choose a Quiet Room: Background noise can cause flicker.
Sing a Single Note: Hold it steady for 3–5 seconds.
Watch the ±Cents Meter: Aim for 0–5¢ stability for best accuracy.
Try Scales & Exercises: Move through intervals slowly for training.

Practical Exercises to Try

Exercise Name	Purpose	How to Do It
Steady Note Hold	Pitch stability	Hold one note, aim for 0–5¢ deviation
Scale Ascend/Descend	Interval accuracy	Sing do-re-mi up/down, check each note
Interval Jumps	Ear training & intonation	Leap 3rds, 5ths, octaves
Vibrato Control	Vibrato width control	Watch ±cents amplitude as you sing
Warm-Up Vowels	Tone & consistency	Ah-Ee-Oo vowel slides

Troubleshooting Tips

Flickering readings: Use a quieter room or steadier vowels.
Weak signals: Check microphone input levels.
High notes dropping out: See our guide on Whistle & High Register Detection for better accuracy.
