How it works
Pitch is how high or low a voice sounds, and it is measured here in semitones, the steps on a piano. Moving the slider to +12 doubles the pitch frequency and the voice jumps an octave up; −12 drops it an octave down. Small moves of two or three semitones sound like a naturally different person, while big moves are the cartoon and character effects you hear in short videos.
This tool shifts pitch the simple, honest way: by playing the recording faster or slower, the way speeding up a record raises the singer's voice. That means pitch and tempo move together. A higher voice also plays a little quicker, a deeper voice a little slower. For voice notes, character voices, practice tracks and fun clips, that trade-off is exactly what most people want. Your file is decoded and re-rendered on your own device with the Web Audio API, and it is never uploaded anywhere.
Questions people ask
Does changing the pitch change the speed too?
Yes, in this tool the two move together, like a record played faster or slower. A clip shifted up sounds higher and plays shorter; shifted down it sounds deeper and plays longer. The download keeps the same relationship you hear in the preview.
How do I make a voice sound deeper but still natural?
Try −2 to −4 semitones. That range lowers a voice believably. Beyond −6 most voices start to sound like a deliberate effect rather than a different person.
Is my audio uploaded to a server?
No. The file is read and processed by your browser, and the WAV you download is built on your device. Nothing is sent or stored.
Why is the download a WAV file?
WAV is the format the browser's audio engine produces directly, with no quality loss from re-encoding. It is larger than MP3, so for long clips expect a bigger file. Any audio converter can turn it into an MP3 afterwards if you need one.
