Questions
Is the robot voice changer free?
Yes, 100% free. No sign up, no watermark and no limits.
Does my file get uploaded?
No. Your file never leaves your device. Everything happens right in your browser, so it stays private and works on unreleased tracks, beats and voice memos too.
How do I make a robot voice?
Drop your recording in the box and press Play. It starts on the robot settings. Change Robot tone for more or less buzz, then click Export MP3.
How does it work?
Your voice is mixed with a steady tone (ring modulation), which creates the metallic, robotic sound.
Can I make an alien voice?
Yes. Raise Pitch a few semitones and Robot tone to around 400 Hz.
What file types can I use?
Any audio your browser can play: MP3, WAV, M4A, FLAC, OGG and more. Save the result as MP3 or WAV.
No sound on my iPhone?
Turn off silent mode (the switch or Action button on the side), turn up the volume, and press Play again. Older iPhones mute web audio in silent mode.
