  • 🎤 Voice Recording
    You can record your voice with a single click.
    Sound is a vibration that travels through the air. When a person speaks, their voice creates these vibrations, which can be captured as digital data by a microphone on your computer or phone.
    For example, if you say “Nice to meet you,” the sound can be visualized like this: Waveform of the Audio(Original)

  • 🔁 Reverse Playback
    Instantly reverse the recorded voice.
    By flipping the audio data along the time axis, the sound is played backward. Waveform of the Audio(Reversed)

  • 🔼🔽 Pitch Adjustment
    Modify the pitch to make your voice sound like a chipmunk or robot.
    Even though it’s called Voice Reverser Online, we added this feature because it was easy and fun.
    Changing the speed of playback without altering duration affects frequency: faster playback raises pitch, while slower playback lowers it. Waveform of the Audio(Pitch transform)
