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).

Virtual Singing Lessons: Using the Voice Pitch Analyzer Online

With more singers turning to online vocal lessons and virtual choirs, pitch accuracy is harder to monitor than in traditional classrooms or rehearsal halls.

The Voice Pitch Analyzer solves this problem by giving real-time, visual pitch feedback for teachers, students, and choirs — even in remote settings.

This guide shows you how to use the analyzer effectively for online singing lessons and rehearsals.

Why Pitch Accuracy Is Harder Online

Latency: Video calls delay audio, making real-time corrections difficult.
Variable mic quality: Students use laptops, tablets, or phones with different mics.
Background noise: Home environments add distractions.

The Voice Pitch Analyzer bypasses these issues by letting singers see their pitch accuracy instantly, even when lessons happen over Zoom, Skype, or Google Meet.

Setting Up the Voice Pitch Analyzer for Online Lessons

Open the Tool: Voice Pitch Analyzer
Use a Secondary Device: Students can run the analyzer on a tablet/phone while video calling on another device.
Allow Microphone Access: All processing happens locally — nothing is uploaded.
Share the Screen (Optional): Teachers can watch the student’s pitch feedback in real time.

Teaching Activities for Virtual Lessons

1. Pitch Matching

Teacher plays or sings a note.
Student sings it back while watching the analyzer’s ±cents reading.
Aim for 0–5¢ deviation before moving on.

2. Scale & Interval Training

Student sings ascending/descending scales slowly.
Analyzer shows accuracy on each note.
Teacher gives immediate correction if notes drift sharp/flat.

3. Vibrato & Control Work

Student sings a note with vibrato.
Analyzer shows vibrato width and consistency visually.
Teacher adjusts breath support or vowel shape as needed.

For vibrato-focused training, read Vibrato & Pitch Stability: How to Use the Analyzer for Control.

4. Group Rehearsals for Virtual Choirs

Each singer practices individually with the analyzer before recording.
Ensures consistent pitch accuracy across all parts before final mixing.
See Choir Practice with the Voice Pitch Analyzer for full details.
