[Voice Changer](https://edesy.in/tools/voice-changer) turns a recording into a robot, a deep voice, a chipmunk and more. It is made for fun and creative projects, and your audio is processed in your browser, never uploaded.

## How to Use

1. Under **Voice source**, choose **Record** or **Upload file**.
   - **Record**: click **Start recording**, allow microphone access, then click **Stop recording**. Click **Record again** to replace the clip.
   - **Upload file**: drop an audio file (MP3, WAV, M4A, FLAC, OGG and more).
2. Pick an **Effect**: Pitch only, Robot (selected by default), Deep, Chipmunk, Echo, Radio / phone, Alien or Cave / hall.
3. Adjust **Pitch** (-12 to +12 semitones) and **Effect amount**.
4. Choose a **Download format**: WAV (default) or MP3.
5. Click **Apply effect** and listen to the result in the player.
6. Click **Download WAV** or **Download MP3**.

## Things to know

- **Recording length**: recording stops by itself after 5 minutes.
- **Keep original speed**: on by default, so the pitch changes but the timing stays the same. This uses an audio engine of about 30 MB, loaded once. Turn it off for a faster tape-style effect where higher pitch also plays faster.
- **MP3**: encoding to MP3 also loads the audio engine the first time. If MP3 encoding fails, you can still download the WAV.
- **Effect amount** blends the effect with your original voice. Lower means more of the original. It shows "n/a" for effects that only change pitch (Pitch only, Deep, Chipmunk).
- **Changing a setting** after applying means you need to click **Apply effect** again.
- **Browser support**: needs Web Audio rendering, which current Chrome, Edge, Firefox and Safari have.
- **Privacy**: audio stays on your device.

## Tips

- Pitch only with a few semitones up or down is the most natural-sounding change.
- Echo and Cave / hall sound clearer at a lower effect amount.
