# Audio in the editor

> Set levels, mix tracks, match loudness for YouTube or podcasts, duck music under speech, shape sound with EQ and dynamics, and record your own voice.

**Where:** Video editor › AI mode: Off › the inspector's Mixer and Sound tabs

The editor has the audio tools of a professional editor: clip gain, a track mixer with automation, loudness matching, ducking, EQ and dynamics, and live meters. Everything on this page is free. For noise removal and voice enhancement, see [Audio cleanup](https://docs.muvomi.com/sound/audio-cleanup/); for AI voices and music, see [Voiceover](https://docs.muvomi.com/sound/voiceover/) and [Music](https://docs.muvomi.com/sound/music-and-effects/).

## Clip volume and gain

-   **Volume** in **Effect Controls** sets a clip’s level, with **Fade in** and **Fade out**.
-   **Audio gain…** (<kbd>G</kbd>, or right-click a clip) sets gain before effects: **Set gain to**, **Adjust gain by**, **Normalize max peak to** or **Normalize all peaks to**.
-   **The volume line** on an audio clip can be shaped by hand: drag a point, <kbd>⌘</kbd>\-click the line to add one, <kbd>⌥</kbd>\-click to remove one.
-   **Panner** in **Effect Controls** places the sound left or right.

## The Audio Track Mixer

Open the **Mixer** tab (<kbd>⇧</kbd><kbd>6</kbd>). Every track with sound has a strip with a meter, **Mute**, **Solo**, **Arm to record**, a pan knob and a fader (−60 to +6 dB), plus a **Master** strip. Use the stopwatch to automate a fader or pan over time.

## Essential Sound

Open the **Sound** tab. Choose a clip and set its **Type**: Dialogue, Music, SFX, Ambience, or **From what it is**.

| Section | What it does |
| --- | --- |
| **Loudness** | Choose a **Target**: −14 LUFS (YouTube, Spotify and most online), −16 LUFS (podcasts and Apple) or −23 LUFS (broadcast, EBU R128). Press **Match the chosen clips** or **Match every clip**. **Measure the mix** reports the edit’s loudness and true peak. |
| **Repair and clarity** | **Reduce noise, hum or reverb…** opens [Audio cleanup](https://docs.muvomi.com/sound/audio-cleanup/). EQ presets **Voice clarity**, **Low cut**, **De-ess** and **Warmth**, and **Even out the voice**. |
| **Ducking** | Set **Reduce by**, **Fade down** and **Fade up**, then press **Duck under speech**. Music is lowered with keyframes wherever someone speaks. |
| **Remix** | Shortens a music clip so it ends on time, taking whole bars out of its middle with crossfades on the beat. Choose where it should end and press **Remix to end at…** |

## EQ and dynamics

In **Effect Controls**, each sound clip has:

-   **Parametric Equalizer** with presets (Voice clarity, Low cut, De-ess, Warmth, Telephone) and up to eight bands you can drag on the curve.
-   **Dynamics** with presets (**Voice leveler**, **Gentle**, **Broadcast**, **Limiter only**) and controls for threshold, ratio, attack, release, knee, makeup gain and a limiter.

## Meters

The meter beside the preview shows peak levels and short-term loudness in **LUFS**. Hover for the integrated loudness. A peak at 0 dBFS lights the clip warning.

## Record your voice

Record your own microphone straight onto the timeline.

1.  Move the playhead to where the recording should start.

2.  Press **Record** in the tool row (or **Record voice-over on…** in an audio track’s **⋯** menu).

3.  Choose the **Track**, and whether to **Count in for three seconds**.

4.  Press **Record** and allow the microphone if your browser asks. The edit plays while you speak.

5.  Press **Stop**. The take is saved to your media and placed on the track.

Anything already on the track at that point is recorded over; **Undo** brings it back.

> **Tip:** Ask the AI for mixing jobs in words: *“Duck the music under the speech”*, *“Match the loudness for YouTube”* or *“Pan the guest to the right.”*

## Troubleshooting

| You see | What to do |
| --- | --- |
| *Choose a clip with sound first.* | Select an audio clip, or a video clip with sound. |
| *Those clips are silent.* | The chosen clips have no sound to adjust. |
| *The microphone could not be used.* | Allow the microphone for muvomi.com in your browser’s site settings, then try again. |
| *This browser cannot record sound.* | Use a current version of Chrome, Edge, Firefox or Safari. |
| *A nest is open: loudness is matched for the whole edit.* | Close the nest first. |
