Audio editing

Mix and edit audio: volume, fades, effects, and separation. Balance music, voice, and sound effects for a professional mix.

Control your mix. Adjust levels, add fades, apply effects, and keep your sound clean and balanced.

Audio tracks

  • Audio tracks — separate tracks for music, voice, SFX
  • Embedded audio — audio from video clips
  • Linked vs unlinked — video+audio together or separate

Volume control

Drag the volume line

  • Hover clip, see horizontal line
  • Drag up/down for louder/quieter
  • Measured in dB (decibels)

Properties panel

Select clip → Properties → Audio:

  • Volume — precise dB value
  • Mute — toggle off
  • Stereo/mono — channel configuration

Fades

Add smooth transitions:

  • Fade in — gradual volume increase at start
  • Fade out — gradual decrease at end

Drag fade handles (small squares on clip corners):

  • Drag right from start — fade in duration
  • Drag left from end — fade out duration

Audio effects

Apply to clips:

Equalizer (EQ)

  • Low shelf — bass boost/cut
  • Mid gain/freq/Q — presence, clarity
  • High shelf — treble, air

Compressor

  • Threshold — when compression starts
  • Ratio — amount of reduction (4:1, 8:1)
  • Attack/Release — reaction speed
  • Knee — smoothness of onset

Reverb

  • Synthetic impulse response
  • Adds space/room to flat audio

Delay

  • Echo effect
  • Feedback and time controls

Noise reduction

  • Reduces background hiss/hum
  • Strength control

Voice changer / pitch shift

  • Changes pitch without duration change
  • Cartoon, robot, or musical effects

Audio extraction

Separate audio from video

  1. Select video clip
  2. Right-click → "Separate audio"
  3. Audio appears on separate audio track
  4. Video and audio now unlinked, can move independently

View waveform

Waveforms show audio amplitude over time:

  • Tall peaks — loud sections
  • Quiet valleys — silence or soft audio

Linked clips

By default, imported video keeps audio and video together:

  • Linked — move together, delete together
  • Unlinked — move separately

Toggle link:

  • Select clip
  • Press L
  • Or right-click → "Unlink"

Using the agent for audio

Let the agent mix for you:

"Auto sound design"

"Balance the audio with voice upfront"

"Mix music ducking under voice"

See Auto sound design for details.

Keyboard shortcuts

| Key | Action | |-----|--------| | L | Link/unlink selected clips | | M | Mute selected clips | | Shift + M | Unmute selected clips |

Tips

  • Headroom — peak around -6dB, final mix -12 to -14 LUFS
  • Music ducking — lower music when voice speaks (agent can auto)
  • Clean voice — use EQ to cut low rumble (below 80Hz) and harsh highs (above 10kHz)
  • Compression — smooths vocal dynamics; start with 4:1 ratio, 10dB reduction
  • Reverb sparingly — subtle adds depth; obvious sounds artificial
