# Audio editing

> Adjust the speed and pitch of generated audio files.

A feature that edits the speed and pitch of already generated or uploaded audio files (TTS, recordings, etc.) via text requests.

## How to use

Select the audio file you want to edit, then make your request in the Chat.

### Speed adjustment (0.5x \~ 2.0x)

You can adjust between 0.5x and 2.0x.

```text theme={null}
Speed up this voice to 1.7x.
```

```text theme={null}
Slow down this audio to 0.8x speed.
```

### Pitch adjustment (-12 \~ +12 semitones)

You can adjust the voice pitch in semitone units from -12 to +12.

```text theme={null}
Raise this voice by one semitone.
```

```text theme={null}
Change this audio voice to a lower pitch.
```

<Tip>
  You can adjust both speed and pitch at the same time. Try requesting "Speed up this voice to 1.5x and lower the pitch a bit."
