These examples show the kind of readout you get: note name, frequency, and cents.

The pitch detector picks up whatever you're doing and shows the note name (like A4 or C#3), frequency in Hz, and how many cents sharp or flat you are. It all updates live as you go.
Copy the reading into your DAW or practice notes. Or stick around — you can detect the key of a full track, generate backing music, or master your recordings right here on BeMusic.
When you know your exact pitch, everything changes — how you practice, how you perform, how you produce. Here's how people actually use this vocal pitch detector.
Watch every note you sing show up on screen as you sing it. The cents gauge shows where you're drifting, so you can build muscle memory for clean intonation instead of guessing.
Check Your Vocal Pitch
Don't have a dedicated tuner handy? Pluck a string or blow a note and the detector shows the note it hears plus the cents deviation, sharp or flat. It works best on one clearly pitched sound at a time, like guitar, violin, or brass. For critical tuning, check against a hardware tuner.
Tune Your Instrument
Sing a note, glance at the screen, and find out if your ear got it right. Teachers can pull this up during lessons for visual feedback.
Start Ear Training
Need to check if the altos are drifting? Have one singer hold a note and the detector settles the argument on screen — no piano required, no stopping the rehearsal.
Check Section Pitch
Before you reach for Auto-Tune, check if the take is actually off. Sing into the mic or upload a recording — the detector shows you exactly which notes need work and which ones are fine.
Check Recording Pitch
Working on your speaking voice? The live display shows frequency shifts as you speak, which can help with voice coaching, accent work, or getting your presentation pitch where you want it.
Analyze Your VoiceIt runs in your browser, it keeps your audio on your device, and it plugs into a full music toolkit.
The detector shows pitch as a note name, a frequency in Hz, and a cents offset (1 cent is 1/100 of a semitone), rounded to whole cents. The estimate comes from the McLeod Pitch Method (via the Pitchy library) and is smoothed over time. We haven't published benchmark results, so real accuracy depends on your microphone, your room, and the sound you play.
In mic mode the reading updates about 10 times per second, so the screen follows you as you sing or play. The actual delay also depends on your device, browser, and microphone.
Mic input and uploaded files are analyzed in your browser. Your audio is not uploaded to our servers, and no account is needed.
If it has a browser and a mic, it works. Desktop, laptop, phone, tablet — Chrome, Safari, Firefox, Edge. Just open the page and go.
Works best on one clearly pitched sound at a time, such as voice, guitar, violin, flute, or brass. Chords, noisy rooms, and very breathy or distorted sounds are harder, and readings below a clarity threshold are ignored.
You get three things at once: the note name (like A4), the exact frequency in Hz, and how many cents sharp or flat you are. No flipping between modes — it's all right there.
Practice on your phone during a commute, or go full desktop in the studio. The interface fits whatever screen you've got, though results can vary with the device's microphone.
Got your pitch? Now detect the key of a full track, generate AI music in the same key, split stems, or master your recordings — all without leaving BeMusic. No more bouncing between five different apps.
Quick answers to the things people ask before they start detecting.
It's a tool that listens to sound — from your mic or an audio file — and tells you what musical pitch it hears. You get the note name (like A4 or C#3), the exact frequency in Hz, and how many cents sharp or flat you are. Unlike Auto-Tune or other pitch correction tools, a pitch detector just measures — it doesn't change anything.
It reports pitch to the nearest cent, using the McLeod Pitch Method on short windows of audio and ignoring readings below a clarity threshold. We haven't published benchmark results across devices, ranges, or noise levels. Clean input from a good microphone gives the steadiest readings; background noise, heavy vibrato, and chords can make the reading jump or disappear. For critical tuning, compare against a hardware tuner.
Yes. You can detect pitch without paying or creating an account, and the tool has no daily limit.
Nope. The whole thing runs in your browser — Chrome, Safari, Firefox, or Edge. Open the page, allow your mic, and you're detecting. Works on phones, tablets, and desktops.
It reads one pitched sound at a time — vocals, guitar, violin, flute, trumpet, piano (one note at a time). It estimates the fundamental frequency, so very noisy or polyphonic sounds may not return a reading.
A tuner expects a specific note and tells you if you're on it. A pitch detector figures out whatever note you're making — across the full musical range — without assuming what you're going for. Think of a tuner as a yes/no check and a pitch detector as an open-ended answer.
Mic input and uploaded files are analyzed locally in your browser using the Web Audio API. Your audio is not uploaded to our servers, so we don't record or store it.
A cent is 1/100th of a semitone — basically the smallest useful unit for measuring how far off your pitch is. If the detector reads +12 cents, you're a hair sharp. -8 cents means a touch flat. Most people can't hear a difference smaller than ±5 cents, so anything in that range sounds in tune.
For sure. Sing a note, check the screen, see if your ear got it right. Do that enough times and you'll start calibrating your internal sense of pitch against the detector. Teachers love pulling it up during lessons for instant visual feedback.
Yes. Open the page in your mobile browser, allow mic access, and you're good. The same method runs on every device, but results can vary with the phone's microphone.
Yes. Upload an MP3 or WAV file (up to 50 MB) and the detector analyzes the pitch content in your browser. It's handy for checking recordings without replaying them through speakers.
It uses the McLeod Pitch Method (through the Pitchy library), an autocorrelation-based approach. It compares the waveform against shifted copies of itself, finds the repeating pattern, converts that into a frequency, and maps it to the nearest musical note. It all runs in your browser.
Yep. You can shift the A4 reference to match your ensemble or whatever tuning standard you're working with. 432 Hz, 442 Hz, or anything else — just set it and the detector adjusts.
Tons of stuff. Tune your instrument, sharpen your singing, or double-check a recording. Then stick around on BeMusic — detect the key and BPM of a full track, generate AI music in the same key, split stems, remix, or master. The pitch reading is just where it starts.
Most pitch detectors are dead-end pages — you get a note name and that's it. BeMusic hooks pitch detection into a full music toolkit: key detection, AI music generation, stem splitting, remixing, and mastering. So the pitch you detect can actually kick off your next creative move without switching apps.
