Key Features
Everything you need to change audio pitch perfectly
Formant Preservation
Maintain natural voice characteristics when changing pitch. Turn male voices into female without chipmunk effects, or vice versa. Essential for realistic voice transformations.
Musical Intervals
Shift pitch by precise musical intervals - thirds, fourths, fifths, and octaves. Perfect for music transposition, harmony creation, and key changes.
Fine-Tuning Control
Adjust pitch in semitones and cents for precise control. Use high-quality Rubberband algorithm for professional results, especially at large pitch shifts.
9 Pitch Presets
Quick presets from octave down (-12) to octave up (+12), including thirds, fourths, and fifths. Perfect for common use cases like vocal harmonies and transposition.
High Quality Mode
Professional Rubberband algorithm delivers superior audio quality with minimal artifacts, even at extreme pitch shifts. Much better than basic resampling.
Privacy First
All pitch shifting happens in your browser using FFmpeg. Your audio files never leave your device. Perfect for sensitive or unreleased content.
Common Use Cases
Voice Transformation
Change voice pitch for content creation, anonymization, or creative projects. Use formant preservation to maintain natural voice quality when shifting from male to female voice or vice versa.
Music Transposition
Transpose songs to match your vocal range or change the key for different instruments. Perfect for karaoke, covers, and music practice.
Sound Design
Create unique sounds for games, videos, or music production. Shift pitch dramatically for monster voices, alien effects, or robotic sounds.
Vocal Harmonies
Create harmonies by shifting pitch by musical thirds, fourths, or fifths. Layer multiple pitched versions for rich vocal arrangements.

Frequently Asked Questions
What is formant preservation and when should I use it?
Formant preservation maintains the natural voice characteristics when changing pitch. Enable it for realistic voice transformations (male to female or vice versa). Disable it for creative effects or music transposition where you want the natural pitch-shift sound.
What's the difference between semitones and cents?
Semitones are the 12 equal divisions of an octave (like piano keys). Cents are 1/100th of a semitone, used for fine-tuning. For example, +1 semitone = +100 cents. Use semitones for musical intervals, cents for precise tuning adjustments.
Should I use Rubberband or resampling algorithm?
Use Rubberband (high quality mode) for best results, especially for large pitch changes, formant preservation, and professional work. Use resampling (fast mode) only when you need quick processing and can accept lower quality.
Can I pitch shift music without changing tempo?
Yes! Pitch shifting changes only the pitch while maintaining the original tempo. This is perfect for transposing music to match your vocal range or changing keys for different instruments. If you want to change tempo, use the Tempo Changer tool instead.
What file formats are supported?
We support all common audio formats: MP3, WAV, FLAC, AAC, M4A, OGG, WMA, AIFF, and more. You can also extract and pitch-shift audio from video files (MP4, AVI, MOV, MKV).
Are my files safe and private?
Absolutely! All pitch shifting happens locally in your browser using FFmpeg. Your audio files never leave your device or get uploaded to any server. Perfect for unreleased music or sensitive content.
