Features
A complete toolkit for changing how audio sounds, from a quick key change to full vocal isolation, all running locally in your browser.
Pitch & tempo
Shift a track into a new key, change its speed, or do both. Pitch and tempo are independent, so you can transpose without slowing down, or stretch time without detuning. A combined tape-style mode moves both together for a natural varispeed feel.
- Semitone pitch shift up or down
- Independent tempo change
- Tape-style combined speed
- Keeps rhythm intact
Tone shaping
Reshape the color of a track with spectral tilt, targeted EQ, warmth and gentle saturation. Brighten a dull mix, tame harshness, or add analog-style character without reaching for a full mixing console.
- Spectral tilt and EQ bands
- Notch and shelf control
- Warmth and saturation
- Subtle or heavy
Stereo & space
Control the width and movement of the stereo image. Widen a narrow mix, add slow motion for a sense of space, and work in mid/side to treat the center and the sides separately.
- Stereo widening
- Mid/side processing
- Movement and jitter
- Reverb space
Vocal effects
Thicken and texture a voice with chorus, flanging and doubling. Go from a gentle sheen that sits a vocal nicely in a mix to heavy, obvious modulation for a creative effect.
- Chorus and flanger
- Doubling and detune
- Subtle to extreme
- Targets vocals
Melody to hum
Follow the melody a singer is performing and re-synthesize it as a clean, wordless hum. Useful for practicing a line, sketching an idea, or replacing a vocal with a neutral melodic guide.
- Tracks the sung melody
- Wordless hum synthesis
- Clean, tonal result
- Uses stem separation
Voice anonymize
Transform the identifying characteristics of a voice so a recording can be shared without revealing the speaker, while keeping the words understandable.
- Alters voice identity
- Keeps speech intelligible
- Privacy-preserving
- Adjustable strength
Stem separation
Split a finished mix into vocals and instruments right in the browser. Separation lets any other effect target just one part of the track, for cleaner and more musical results.
- Vocals and instruments
- Runs in the browser
- WebGPU with WASM fallback
- Cached after first use
