## Adjust a clip

Select a video or audio clip, expand **Audio** in Properties, then choose **Volume**, **Pitch**, or **Equalizer**. A linked video edits its matching audio companion.

| Control | Range |
| --- | --- |
| Gain | -60 dB to +12 dB (−60 dB effectively mutes the clip) |
| Fade In / Fade Out | 0 to 5 seconds each |
| Pitch | Semi Tones and Cents, independent of speed |

> **Tip:** You can also drag the volume line and fade handles directly on the clip in the timeline, and **Gain** can be keyframed to rise or fall over a clip.

## Pitch and tone

- The **Pitch** controls shift pitch without changing clip speed. To change speed instead, expand **Playback** and use **Speed**.
- The **Equalizer** tab keeps the complete six-band response graph, presets, enable/reset controls, filter types, frequency, gain, Q, and output controls.

## Record a voiceover

The **Record voiceover** (microphone) button in the timeline toolbar records narration in time with your project. Capture runs **while the timeline plays**, and the finished take lands on a new audio track anchored to the playhead position where you started.

1. Move the playhead to where the voiceover should begin.
2. Click the **microphone** button — the timeline starts playing and recording begins.
3. Use **Pause recording** to stop the playhead and mic together, **Resume recording** to continue, and **Stop and save** to finish and drop the clip onto a new audio track.
4. Click **Cancel recording** (the ✕) to discard the take without adding anything.

Open **Microphone settings** (the ▾ next to the button) to choose an input device and tune capture. The level meter there is live, so you can check your mic before recording.

| Setting | What it does |
| --- | --- |
| Noise suppression | Reduces steady background noise. On by default. |
| Auto gain | Keeps your voice at a consistent level. On by default. |
| Mute timeline while recording | Silences the timeline monitor so speaker audio does not bleed into the mic. On by default. |
| Sync offset | Nudges the recorded clip earlier or later to compensate for input latency (up to ±1000 ms). |

> **Tip:** Use headphones so your project audio is never captured by the mic — then you can turn **Mute timeline while recording** off to hear the mix as you narrate.

> **Warning:** Seeking is disabled while recording, and pressing `Space` or reaching the end of the timeline finishes the take. This keeps the recording locked to the playhead so it can never drift out of sync.

## Clean up dialogue

- **Remove Silence** finds silent ranges and cuts them; the **Minimum Silence** setting controls how long a gap must be, and the dialog estimates how much will be removed.
- **Remove Filler Words** detects words like um and uh from the transcript and audio and removes them.
- Both tools show the ranges they will remove so you can preview before applying the edit.

> **Tip:** A transcript improves filler-word detection, so generate one first for the best results.
