## Overview

Uses resampling-based pitch and formant movement, duration compensation, spectral shaping, and gentle dynamics control. The output can reduce obvious gender-coded voice cues but does not guarantee anonymity against biometric speaker-recognition systems. Listen for intelligibility before publishing.

## Inputs

- **Audio File** (file)
- **Shift Direction** (select)
- **Strength (semitones)** (number)
- **Output Format** (select)

## When to use

- When you need to reduce obvious gender-coded voice cues in a recording.
- When publishing interviews, commentary, or user-generated audio with added voice privacy measures.
- When you want to shift a voice higher or lower while keeping the original duration.

## How it works

- Upload one audio file in a supported audio format.
- Choose whether to shift the voice higher or lower.
- Set the shift strength from 1 to 6 semitones.
- Select WAV, MP3, FLAC, or M4A as the output format, then review intelligibility before publishing.

## Use cases

- Add a privacy layer to interview recordings and voice commentary before publication.
- Reduce recognizable gender-coded cues in user-submitted audio.
- Create a shifted-voice version of a recording while preserving its original duration.

## Frequently asked questions

### What does this tool change?

It changes pitch, formant cues, spectral characteristics, and dynamics to reduce obvious voice-identification signals.

### Will the processed audio keep the same duration?

Yes. Duration compensation is used to preserve the recording’s length.

### Can I shift the voice higher or lower?

Yes. Choose Higher or Lower, then set a strength from 1 to 6 semitones.

### Which output formats are available?

You can export the result as WAV, MP3, FLAC, or M4A.

### Does this guarantee voice anonymity?

No. It reduces obvious cues but does not guarantee protection against biometric speaker-recognition systems.
