Frequently Asked Questions
Does this affect the tempo of my file?
No, that is the default behavior. The tool uses a phase vocoder to change the pitch while maintaining the original length and speed of the audio.
What are Formants?
Formants are the acoustic resonances of the human vocal tract. When you pitch a voice up without formant correction, the vocal tract sounds artificially shrunken (the chipmunk effect). Formant preservation prevents this.
Is this tool completely private?
Yes. All processing is done locally in your browser using WebAssembly. Your audio files are never uploaded to any server, ensuring complete privacy.
What file types are supported?
We support uncompressed PCM formats including WAV and AIFF across 16-bit, 24-bit, and 32-bit float bit-depths.
