## A clip's sound
Select a clip and open the **Audio** tab in the inspector:

- **Volume** and **Pan** (left to right).
- **Fade in** and **Fade out**: drag them, or the small handles at the top corners of the clip on the timeline.
- **Bass** and **Reverb**. **Slowed + reverb** does the slowed, roomy sound in one tap.
- **Mute** silences the clip.

A video's sound is linked to its picture: they move and cut together. **Unlink** (`Ctrl+L`) separates them, to move the sound on its own or delete it.

The waveform drawn on a clip follows its volume, so you can see a fade.

## A track's sound
Click a sound track's head to show its EQ in the inspector: four bands drawn as a curve, which change how much of the low, middle and high sound you hear. Drag a numbered point across for its frequency and up or down for its gain. **Presets** has ready shapes such as voice clarity, or a phone's sound. **M** and **S** on the head mute the track or play it alone.

For changes over time, add an automation lane: right-click the track's head and choose **Add automation: Volume** (or pan, or a filter). See [The timeline](https://driftedit.app/manual/timeline/).

## Stems: a song in four parts
**Split into stems** (in Techniques under **Sound**, or a sound clip's menu) separates a song into vocals, drums, bass and the rest, each on its own track under the song, which is muted. Turn the vocals down under speech, cut to the drums alone for a drop, or make a remix. It runs on your device: the model is 157 MB, downloaded once, and a 76 second song takes about 23 seconds on a fast computer.

## A cleaner voice
- **Clean up the voice** turns down rumble and steady room noise, evens out the level and sets it to -16 LUFS, a measure of how loud it sounds, about what most platforms play at. Switch it off and on to compare; set its strength. The original recording is kept.
- **Isolate the voice** lifts the dialogue out of music and effects with a model on your device (31 MB, once).
- **Lower the music under speech** turns the music down while someone talks and back up between phrases.

These are in the **Audio** tab and in Techniques, under **Talking-head video**. See [Techniques and still frames](https://driftedit.app/manual/techniques/).

## The Library's sounds and beats
**Library**, **Sounds** has whooshes, risers, booms, hits, glitches and more; **Beats** has loops in several genres. All of them are made in code by DriftEdit, free to use in anything you export. Press one to hear it, then drag it onto the timeline. A beat can be the song for auto mode.

> [!WARNING] Music you did not make
> Video platforms recognise songs and may mute, claim or remove a video that uses one without a licence. Use music you have the rights to, or the Library's beats.
