Audio clips on the timeline

Adding a file, moving and trimming the clip, the Track settings, loop, mute, analysis.

A song or a voice-over that belongs to the timeline lives there as a clip: it starts, pauses and scrubs with the playhead, and it can feed the analysis that makes visuals react. This page is about clips. For a click sound or an ambience that a rule starts, read Playing a sound from a rule instead — that needs no clip at all.

01Getting a file in

Audio files go into the library first. Open the Files tab in the left panel and drop an mp3, wav, ogg or m4a onto it, or use the import button at the top of the tab. The file appears as a card with a letter glyph instead of a thumbnail.

An audio card in the Files tab, with the ▶ and ♪ buttons on its bottom row

Two buttons sit on every audio card:

  • ▶ — listen. It plays the file once, without adding anything to the timeline; it turns into ■ while playing so you can stop it.
  • ♪ — put the file on the timeline as a clip. On a file that is already there, the same button removes it again.

02Adding a clip from the timeline

The other door is in the timeline itself. ♪ + Audio in the transport strip lists every audio file in the library that is not on the timeline yet — pick one and it lands as a clip starting at 0 and is selected, so its settings open on the right straight away.

The ♪ + Audio flyout listing the audio files that are not on the timeline yet

If the list is empty the flyout tells you why: either every file is already on the timeline, or there is no audio in the library yet.

A file can be on the timeline once. To use the same file twice, import it twice.

03The clip on the timeline

Clips are rows in the Keys view of the timeline, each with a ♪ name label and a waveform drawn against the same ruler as your keyframes. Press Play (Space) and the sound follows the playhead; scrub the ruler and it scrubs too.

A clip row on the timeline: the ♪ label, the waveform, and the two edge handles on the selected clip

Three gestures shape a clip, and the cursor tells you which one you are about to make:

Where you dragWhat happens
The body of the clipMoves it — Start changes, snapped to frames
Its left edgeTrims the beginning: the clip gets shorter from the left and the content stays where it was
Its right edgeSets the Length

Clicking outside the clip scrubs the playhead, exactly like clicking the ruler. Each drag is one undo step (Ctrl+Z takes the whole move or trim back).

A looping clip is drawn repeating to the end of the scene; a muted one is drawn dimmer. The handles are only on the first repeat — trimming cuts the file, not the repeats. A clip that is still decoding says loading… where the waveform will be.

Nothing plays until you have clicked or pressed a key somewhere in the editor at least once — browsers only let a page make sound after a real gesture. If a clip stays silent on the first Play, click the canvas and try again.

04The Track settings

Click the ♪ name label (or the clip itself) and the Properties panel switches to the clip. There is nothing else to select at the same time, so the panel shows only the track: its name at the top, the file it plays and its state (loading…, playing, the file length, or error), and one section:

The Track section in Properties: File, Gain, the Timing trio, Loop, Muted, Analyze and Remove track
ControlWhat it does
FileWhich library file the clip plays — read-only here; remove the track and add another file to change it
GainVolume of this clip, 0–2. 1 is the file as recorded
Start (ms)Where on the timeline the clip begins — the same value the drag writes
Trim in (ms)How much of the beginning of the file is skipped — the left-edge drag
Length (ms)How much of the file plays. 0 means "to the end" — the right-edge drag
LoopStart over when the clip ends. A trimmed clip loops over its trimmed length
MutedSilent — but still analyzed (see below)
AnalyzeFeed the audio analysis from this clip, so visuals can react to it. On by default; turn it off on clips that are just background
× Remove trackTakes the clip off the timeline. The file stays in Files

The numbers and the drags are two views of the same values — drag roughly, then type the exact millisecond.

Muted plus Analyze is a useful pair: the audience never hears the track, but every bass hit still drives the scene. That is how you make a silent visual that keeps a musician's timing.

05Analysis and volume

Every clip with Analyze on contributes to one shared analysis while it plays, together with the microphone when that is live. What the analysis measures, how to tune it, and the overall Master volume are all in the Audio popover in the top bar — see Timeline audio, microphone & analysis. To make something react, continue with Visuals that react to sound.
