It moves the pitch without moving the clock. The cheap way to raise a voice is to play the recording faster, which raises pitch and shortens the take at the same time — that is the chipmunk effect, and it is why so many voice changers only sound like a joke. Working in the frequency domain instead lets the pitch move while the timing stays exactly where it was, so the result still fits the video it came from. On top of that there is separate formant control, which shifts the resonances of the vocal tract: pitch alone makes you sound like yourself sped up, while formants are what make a voice read as a different body. Presets, echo, distortion, reverse and the vocoder all sit on that base.

Speaker identification relies on formant patterns (resonant frequencies of the vocal tract). Simple pitch shifting can be reversed. Formant shifting changes these resonant patterns, making the voice sound like a completely different person. Combining pitch shift, formant shift, and ring modulation makes identification virtually impossible.

Formants are the resonant peaks produced by your vocal tract (throat, mouth, nasal cavity). They determine the perceived character of your voice — whether it sounds male, female, young, or old. Formant shifting moves these resonances independently from the pitch, allowing you to change the perceived gender or age of a voice without the "chipmunk" effect.

A vocoder analyzes your voice into frequency bands and uses those bands to modulate a synthesizer carrier signal (sawtooth, square wave, or noise). The result is a robotic, synthesized version of your speech that preserves the rhythm and articulation but replaces the natural voice with a synthetic timbre.

The Speed control changes how fast the audio plays back (0.5x to 2x) while automatically compensating the pitch so your voice doesn't sound higher or lower just from the speed change. This lets you create slow-motion or fast-forward effects while keeping the voice transformation accurate.

The phase vocoder introduces approximately 40ms of latency due to the FFT analysis window. This is below the threshold of noticeable delay for most users, especially with headphones. Use headphones to prevent audio feedback.

Yes. Record your transformed voice using the voice recorder, download the file (WAV, MP3 or OGG), and import it into your video editor. For live streaming, use the microphone mode with headphones and route the audio output to your streaming software via a virtual audio cable.
