## Overview

Analyze a vocal recording locally with a bounded YIN-style cumulative mean normalized difference (CMNDF) pitch tracker. Quiet or aperiodic frames are discarded, then only runs of at least three nearby pitches contribute to the estimated range; the 5th and 95th percentile stable notes avoid treating a single breath, crack, or octave error as a singer limit. The report separately retains raw observed extrema, voiced/stable frame counts, confidence, MIDI note numbers, and scientific pitch names. It estimates what is present in the recording; it is not a medical assessment of a person’s full vocal capability.

## Inputs

- **Audio File** (file)
- **Lowest expected pitch (Hz)** (number)
- **Highest expected pitch (Hz)** (number)
- **Tracking sensitivity** (select)

## 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

- Upload one audio file in an audio format supported by the file input.
- Set the lowest and highest expected pitch in hertz, or use the default bounds.
- Choose Relaxed, Standard, or Strict tracking sensitivity.
- The 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.

## Frequently asked questions

### 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.
