How to Change Audio Pitch & Key Online?
Changing the key of a song is essential for vocalists and musicians. With Mp3Edit, you can transpose any track in semitones while keeping the tempo original. Our advanced formant control also allows you to keep voices sounding natural even after a large pitch shift.
Step-by-step Guide:
- Upload: Select the MP3, WAV, or OGG file you want to transpose.
- Adjust Pitch: Use the Transpose slider to shift the key (±12 semitones is one full octave).
- Fine-tune Formants: Use Formant Compensation to prevent the "chipmunk" or "giant" effect on vocals.
- Save: Preview in real-time and download your modified file.
What are Formants?
Formants are the spectral peaks of the sound spectrum of the voice. When you change the pitch, these peaks normally shift, making voices sound unnatural. By using Formant Compensation, you can shift the pitch while keeping the vocal characteristics the same.
