Rate My Singing — Free Online Singing Voice Analyzer

What this singing analyzer measures

Median pitch is the middle of the accepted fundamental-frequency estimates. The detected range uses the lowest and highest accepted frames and is shown in Hertz and nearby musical notes. These endpoints describe this sample, not the full range you can sing reliably. A brief tracking error can widen them; read the contour alongside the summary.

Pitch stability describes short-term changes between neighbouring voiced frames, in semitones. Low, moderate, and high movement are descriptive display bands, not validated performance grades. Even this local measure includes intentional vibrato, slides, and note transitions. A sustained vowel is easier to interpret than a moving melody.

Voiced confidence here means the percentage of analyzed frames with an accepted pitch. It is coverage, not the probability that your singing is correct. Consonants, rests, noise, weak signal, and pitch outside the detector range can all reduce it. The tool does not match a reference song, identify off-key notes, or measure emotion, breathiness, or tonal beauty.

How to get useful feedback from this tool

First try an easy held “ah” or “oo” at a comfortable pitch and volume. Start recording, allow microphone permission, and sing for about 8–15 seconds with natural breaths. Then try a short melody you know well. Keeping these two tasks separate makes a steady tone and a changing phrase easier to interpret.

Repeat the same task two or three times with the same microphone distance and room. A pattern that repeats is more informative than one unusual frame. Avoid accompaniment because the tracker may follow an instrument rather than your voice, and use a moderate level to avoid clipping.

Listen to yourself as well as reading the graph. This tool discards raw audio after analysis and has no playback recorder; use a separate local recorder if you want to replay a take. Notice phrasing, timing, clarity, and expression that the pitch line cannot represent.

Common singing analysis mistakes

Treating a narrow pitch curve as a high score confuses the task with the measurement. A melody should move, and vibrato is often intentional. Compare the same phrase at the same tempo rather than judging every sample against a perfectly flat line.

Noise and excessive volume can make pitch tracking unreliable. Do not sing harder to make the detector accept every frame. Move to a quieter room, check the microphone, and try an easier sound. A single recording is too little evidence for a broad conclusion about ability.

Gaps in the curve are not a diagnosis of breathiness or poor technique. They indicate that the detector did not accept a pitch in those frames. Low coverage, octave jumps, and very brief extremes deserve a repeat recording before interpretation.

How to improve your singing

Begin with a comfortable voice warm up, then pick one manageable practice task. A live pitch detector can show how a held note changes when you have an external reference note in mind. The vocal range test can help you explore comfortable endpoints separately from musical performance.

Record yourself and listen critically but constructively. Choose one phrase to work on and compare takes under similar conditions. A qualified singing teacher can connect what you hear with technique and musical goals; this browser tool supplies a limited set of acoustic observations.
