How to Change the Pitch of a Song
Use the pitch changer in three steps: choose your audio, adjust the semitones, then preview and download.
Choose your audio
Drop one MP3 or WAV into the box, or choose a file from your device. You do not need an account. The tool reads the audio locally, so there is no upload queue to wait for.
Choose a Pitch Shift
Move the slider in one-semitone steps, from −12 to +12. Start with −2 for a slightly lower song or +3 for a brighter key. The tempo stays fixed while you choose the notes that suit your voice or instrument.
Preview and Download WAV
Select Preview result to process your choice. Switch between Original and Shifted at the same position to hear the difference. Download the WAV when you are happy. Change the slider and preview again to try another key; every version is free.
Pitch Changer Features
Control the key of an existing recording, with clear limits on what changes.
01 / Pitch shift
Adjust Pitch from −12 to +12 Semitones
Move from −12 to +12 semitones in whole steps. Start at −2 or +2, compare the result, and adjust until the recording suits your range. This is a pitch shifter, not automatic key detection.
02 / Same tempo · same duration
Keep the Same Speed and Duration
Changing the pitch moves every note up or down by the same amount, while the tempo and the length of the track stay exactly the same. One semitone is one key on a piano, so +2 raises a song by a whole step and −12 drops it a full octave. If you need a song to be faster or slower instead, this page only changes the key. A value of 0 leaves the notes in their original key and still lets you export a WAV.
Who is this pitch changer for?
For people working with a recording they already have, rather than creating a new song from scratch.

Ways to Use a Pitch Changer

Start at −2 semitones, check the highest and lowest notes, then rehearse at the original tempo. If you need an instrumental first, prepare one with the karaoke maker.
Prepare a karaoke trackChange a Song’s Key for Practice
Use this pitch changer to transpose a recording into the key you are learning and play along. The whole arrangement moves together; it does not isolate a single instrument.

Pitch Changer FAQ
Formats, privacy and what to expect from a pitch change.
How do I change the pitch of a song online?
Upload an MP3 or WAV to the pitch changer, adjust the semitone slider, select Preview result, then download the WAV. No account is required.
Does changing the pitch change the speed?
No. The tempo and the length of the track stay the same; only the key changes.
How far can I shift the pitch?
From −12 to +12 semitones in one-semitone steps, which is up to one octave in either direction.
Which file formats are supported?
You can upload MP3 or WAV files up to 50 MiB and five minutes, in mono or stereo. The result downloads as a 44.1 kHz, 16-bit WAV.
Is the pitch changer free?
Yes. You can change the pitch and download the result for free, with no sign-up and no watermark. No credits are deducted, even if processing fails.
Is my audio uploaded to a server?
No. The file is processed in your browser and is not uploaded or stored by Soundora. Remove or replace the file or leave the page to release the temporary result. See our Privacy Policy for general website data practices.
Can I use it as a voice changer?
It shifts the pitch of a whole recording after you choose it. It is not a real-time voice changer and it does not add voice effects or auto-tune.
Can I use the shifted song commercially?
Only if you own the original or have permission to use it. Changing the key does not change who owns the song.
