Frequently Asked Questions (FAQs)

How does browser-based voice changing work without a server?+

Can I use the exported WAV files in Discord or video editors?+

Yes. The studio exports standard 44.1kHz 16-bit PCM WAV files compatible with Discord Soundboard, CapCut, Premiere Pro, and Audacity.

What creates a 'Robot' or 'Walkie-Talkie' voice effect?+

A Robot effect multiplies the voice signal with a 30Hz–50Hz sine wave carrier (Ring Modulation), while a Walkie-Talkie effect applies a narrow 400Hz–2800Hz bandpass filter combined with subtle soft-clipping overdrive.

Is my microphone recording uploaded anywhere?+

Never. Microphone capture and WAV encoding happen 100% inside your browser tab's RAM.

What if I don't have a microphone connected?+

You can upload any existing audio file or click 'Play Synth Demo' to test all DSP presets immediately.
