Overview

Audio Vocal Range Finder estimates the lowest and highest stable sung notes in an audio recording. It analyzes the recording locally, filters quiet or unreliable frames, and returns a JSON report with estimated notes, MIDI values, confidence, and observed pitch statistics.

When to use

Estimate the stable singing range captured in a vocal recording.
Check whether a recording includes a specific low or high note.
Review pitch-tracking results while excluding isolated breaths, cracks, or octave errors.

How it works

1Upload one audio file in an audio format supported by the file input.
2Set the lowest and highest expected pitch in hertz, or use the default bounds.
3Choose Relaxed, Standard, or Strict tracking sensitivity.
4The tool tracks pitch locally, keeps sustained nearby notes, and returns the estimated range as JSON.

Use cases

Singers can estimate the stable range demonstrated by a practice or audition recording.
Vocal teachers can review recorded exercises using note names and pitch-tracking statistics.
Musicians can check whether a recorded vocal line reaches its intended low or high note.

Examples

1. Find a stable A3 singing note

Singer

Background

A singer has a short, clean recording of an A3 vocal exercise and wants to confirm which stable note the tool detects.

Problem

Determine the recorded note without treating brief frame noise as an extended vocal range.

How to use

Upload the A3 WAV recording, set the expected pitch range from 80 to 500 Hz, and select Standard tracking sensitivity.

{
  "minPitchHz": 80,
  "maxPitchHz": 500,
  "trackingSensitivity": "standard"
}

Outcome

The estimated low and high stable notes both remain close to A3.

2. Review a vocal exercise recording

Vocal teacher

Background

A teacher wants to inspect the stable notes demonstrated during a recorded vocal exercise rather than rely on a single accidental pitch event.

Problem

Estimate the recorded low and high notes while limiting analysis to the exercise's expected pitch range.

How to use

Upload the audio recording, enter suitable lowest and highest expected pitches in hertz, and choose a tracking sensitivity that matches the recording quality.

FAQ

What does this tool measure?

It estimates the lowest and highest stable sung notes present in the uploaded recording.

Is the result a complete assessment of my vocal range?

No. It estimates only what is present in the recording and is not a medical assessment of full vocal capability.

Why are isolated cracks or breaths excluded?

Quiet or aperiodic frames are discarded, and stable estimates require runs of at least three nearby pitches.

What do the pitch bounds control?

They define the lowest and highest expected pitches, in hertz, for the tracker to search.

What output does the tool return?

It returns JSON containing the estimated low and high notes plus pitch-tracking details such as MIDI values, confidence, and frame counts.
