Every video layer carries its source audio. Audio-only layers add music, voice, or sound design.
Source audio
When you drop a video clip on the timeline, its audio rides along on the same row. The audio waveform is shown under the video thumbnail.
- Volume — drag the property panel slider or use the per-clip volume rubber-band on the timeline.
- Mute — per layer, with the speaker icon in the layer header.
- Solo — only this layer’s audio plays.
Audio-only layers
Right-click a timeline row → Add layer → Audio. Or drop an MP3 / M4A / WAV / OGG file onto the timeline.
Audio layers do not contribute to the visual composite. They appear as full-width waveform rows.
Trim and split
Identical to video. Drag the edges, Cmd / Ctrl-K to split, drag to move.
Crossfade
Hover the seam between two adjacent audio clips → click the crossfade icon. The two clips overlap by the chosen duration with a linear fade between them.
Gain and pan
Per-clip properties:
- Gain — dB offset, range −60 to +12.
- Pan — stereo left-right, range −100 to +100.
Both are keyframable for dynamic fades and stereo movement. See Keyframe Builder.
Extracted audio
Right-click a video element on the canvas → Extract audio to pull the audio track into a standalone file. The result is a separate audio element you can drop onto the editor timeline.
Music beds
A common pattern:
- Drop a music track on its own audio layer.
- Trim to match the video duration.
- Add a fade-in at the start (keyframe gain from −60 to 0 over 1 s).
- Add a fade-out at the end (gain from 0 to −60 over 2 s).
Limits
- No automatic music sync to cuts (beat-detection) yet.
- Effects (EQ, compression, reverb) are not exposed in the editor — pre-process audio in a DAW before importing.
