Overview

The Audio Set Pitch tool allows you to easily raise or lower the pitch of your audio files in semitones without altering the playback speed. Supporting various formats like MP3, WAV, AAC, and FLAC, this tool is perfect for adjusting vocal tracks, instrumentals, or sound effects to match your desired key.

When to use

When you need to transpose a backing track to a different key to match a singer's vocal range.
When you want to adjust the pitch of voiceovers or sound effects for creative audio production without changing the tempo.
When tuning instrumental recordings or samples to align with the pitch of a larger musical project.

How it works

1Upload your audio file (up to 100MB) in formats such as MP3, WAV, M4A, or FLAC.
2Specify the pitch shift in semitones, choosing a value between -12 (one octave down) and +12 (one octave up) with decimal precision.
3Select your preferred output format, such as MP3, AAC, OGG, or WAV.
4Process the file to generate and download the pitch-shifted audio while preserving the original tempo.

Use cases

Transposing instrumental backing tracks to fit a vocalist's natural singing range.
Creating deep-voice or high-pitched vocal effects for podcasts, video voiceovers, and animations.
Matching the key of different audio samples and loops when mixing music tracks.

Examples

1. Transposing a Backing Track for a Singer

Vocal Coach

Background

A vocal coach needs to adjust an MP3 backing track down by 3 semitones so their student can comfortably sing along during practice.

Problem

The original backing track is in a key that is too high for the student's vocal range.

How to use

Upload the backing track MP3, set the pitch shift to -3 semitones, select MP3 as the output format, and click process.

{
  "semitones": -3,
  "outputFormat": "mp3"
}

Outcome

A new MP3 file is generated with the pitch lowered by 3 semitones, while the tempo and speed remain exactly the same.

2. Creating a Monster Voice Effect

Sound Designer

Background

A sound designer is working on a video game and needs to make a standard human voice recording sound like a large monster.

Problem

The voice recording sounds too human and needs a deeper, more menacing pitch without slowing down the speech delivery.

How to use

Upload the WAV voiceover file, set the pitch shift to -6 semitones, select WAV as the output format, and run the tool.

FAQ

Will changing the pitch speed up or slow down my audio?

No, this tool changes the pitch in semitones while keeping the original playback speed and tempo completely unchanged.

What is the maximum file size I can upload?

You can upload audio files up to 100 MB in size.

What range of pitch shifting is supported?

You can adjust the pitch by up to 12 semitones (one full octave) up or down, in increments of 0.1 semitones.

Which output formats can I choose from?

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

Can I use this tool to fine-tune an instrument?

Yes, because the tool supports decimal values (e.g., 0.5 or -0.2 semitones), you can use it for precise fine-tuning.
