## Overview

This online tool allows you to easily lower the pitch of your audio files without changing the playback speed. By adjusting the pitch in semitones, you can alter the key of music tracks, create deep voice effects, or adapt audio files for sound design while keeping the original duration and tempo completely intact.

## Inputs

- **Audio File** (file): Select an audio file
- **Pitch Shift (semitones)** (number): Measured in semitones. 1 whole tone = 2 semitones, e.g. -2 lowers pitch by 1 whole tone.
- **Output Format** (select)

## When to use

- When you need to adjust a backing track to fit a lower vocal range without altering the tempo.
- When creating deep, dramatic, or anonymous voice effects for podcasts and video voiceovers.
- When tuning instrument samples or sound effects to match the key of a musical project.

## How it works

- Upload your audio file in any standard format up to 100 MB.
- Set the pitch shift value in semitones, ranging from -0.1 down to -12 (one full octave).
- Select your desired output format, such as MP3, WAV, FLAC, or M4A.
- Process and download the pitch-shifted audio file with its original speed preserved.

## Use cases

- Lowering the key of instrumental tracks for singers who prefer a lower register.
- Modifying voice recordings to create deep-voiced character dialogue for animations or games.
- Pitching down drum samples and sound effects to create heavier, darker tones in music production.

## Frequently asked questions

### Which output formats can I choose from?

You can export your processed audio as MP3, AAC, M4A, OGG, Opus, FLAC, or WAV.

### What does a semitone represent in pitch shifting?

A semitone is the smallest musical interval. For example, setting the pitch shift to -2 lowers the audio by one whole tone.
