Pitch studio
Sing into the mic and watch every note land — name, cents, and an eight-second trace.
The voice oscilloscope
Sing or hum any note and watch it land on the dial in real time — note name, cents sharp or flat, and a scrolling trace of your last eight seconds. Pick a target note to practice locking your pitch.

What live pitch feedback shows you
The pitch studio draws the note you are actually singing against the note you are aiming at, as you sing it. Seeing that gap in real time closes the loop that is normally invisible to a singer: you find out you are under the note while you can still do something about it, rather than afterwards.
Pitch detection works by finding the repeating period in the sound your voice makes and converting it to a frequency, then to a note name and a deviation in cents. A hundred cents is one semitone, so a reading of minus twenty cents means you are a fifth of a semitone flat — audible to most listeners, and invisible without a display.
The value of the display is that it separates two problems singers usually confuse. If you can see the target and still cannot land on it, the issue is production — support, register, or effort. If you land on it fine once you can see it, the issue was hearing the target, which is ear training rather than technique.
Everything runs on your device. The audio is analyzed in the browser and never sent anywhere, on any tier.
How to practice with real-time pitch feedback
A few focused minutes with the display beats a long session, because reading a trace while singing is genuinely tiring.
- 01
Allow the microphone and check the reading
Sing a comfortable note and confirm the detector is tracking it steadily. A jumpy reading usually means background noise or a very breathy tone rather than unstable pitch.
- 02
Hold one note and watch the line
Sustain a mid-range note and look at how straight the trace is. Most singers discover a slow drift or a wobble that they could not hear at all from the inside.
- 03
Fix the attack
Watch the first moment of the note. Scooping up from underneath is extremely common, and it shows on the trace as a curve into the target rather than a landing on it.
- 04
Practice the interval you keep missing
Sing from a comfortable note to the one that gives you trouble, and watch where you land. Being consistently under by the same amount is a different problem from landing randomly.
- 05
Look away and check yourself
Sing the same thing without watching, then look at the result. The goal is accuracy without the display — the screen is a teacher, not a crutch.
- 06
Take it into a warmup or a song
The studio is free practice. Scored patterns in warmups and songs are where you find out whether the accuracy holds under a musical demand.
Seeing the note makes it learnable
If you have been told you sing off-key without ever being told which way, this is the fastest fix available. Most people are flat rather than randomly off, and flat is a correctable habit.
- Work in the middle of your range first, where the voice is most controllable
- If you are consistently under the note, try beginning the sound slightly above and letting it settle
- Watch the attack — scooping into a note from below is the most common single habit the display reveals
- Short sessions; reading the trace while singing takes real concentration
Hunt the drift, not the miss
For an accurate singer the interesting information is not whether you hit the note but what happens across the two seconds after you do — where sustained tone bends, and where the trace changes character across a register break.
- Sustain long notes and watch for a slow sag; that is a support problem showing up as a pitch problem
- Sing through your passaggio slowly and watch what the trace does at the transition
- Check whether accuracy degrades with volume — many singers go sharp when they push
- Pro keeps per-note accuracy across sessions, so a weak note becomes a trend rather than a hunch
How does pitch detection work?
The app analyzes the repeating waveform of your voice to estimate its fundamental frequency, then converts that to the nearest note and the deviation in cents. It runs in the browser on your device, and it needs a reasonably quiet room to be accurate at the edges of your range.
What are cents in pitch?
A cent is one hundredth of a semitone. Deviations under about five cents are inaudible to most listeners; twenty cents or more reads clearly as out of tune. The display shows cents so you can see errors long before they become obvious.
Why is the pitch reading jumping around?
Usually background noise, a very breathy tone, or a note near the bottom of your range where the fundamental is weak. Move somewhere quieter and sing with a clearer tone and the reading normally settles.
Will watching a screen make me dependent on it?
Only if you never practice without it. Use the display to identify a habit, then work the same material with your eyes off it to confirm the accuracy carried over.
Is my microphone audio recorded or uploaded?
No. All pitch analysis happens on your device, and nothing is sent to a server or stored unless you explicitly record a take in the recorder — and those stay on your device too.
