Frequently Asked Questions

What is pitch shifting?

Pitch shifting changes the frequency of audio without affecting its duration. This allows you to make voices higher (like helium) or lower (like Darth Vader) while maintaining the original speed.

How do I create a helium voice effect?

Select the "Helium" preset (1.5x) or "Chipmunk" preset (2.0x) to create a high-pitched helium-like voice effect. These presets raise the pitch significantly.

Can I create a Darth Vader voice?

Yes! Select the "Darth Vader" preset (0.5x) to create a deep, low-pitched voice effect similar to Darth Vader's iconic voice.

Does pitch shifting affect audio quality?

No. Our pitch shifter uses professional-grade algorithms that maintain audio quality. The output is exported as high-quality WAV (16-bit PCM).

Is my audio uploaded to a server?

No! All audio processing happens locally in your browser using Web Audio API. Your files never leave your device, ensuring 100% privacy.

Can I use the output commercially?

Yes, all exports are royalty-free. You can use them for personal or commercial projects.
