Robot filter is an audio effect that can be used to make your voice sound robotic. It can be achieved with a variety of software, including Audacity, a free and open-source audio editor.
The robot filter works by changing the pitch and formant of your voice. Pitch is the frequency of your voice, while formants are the frequencies that give your voice its characteristic sound. By changing these parameters, the robot filter can make your voice sound more or less robotic.
