Audio in the editor

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; for AI voices and music, see Voiceover and Music.

Clip volume and gain

Volume in Effect Controls sets a clip’s level, with Fade in and Fade out.
Audio gain… (G, 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, ⌘-click the line to add one, ⌥-click to remove one.
Panner in Effect Controls places the sound left or right.

The Audio Track Mixer

Open the Mixer tab (⇧6). 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. 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.

Move the playhead to where the recording should start.
Press Record in the tool row (or Record voice-over on… in an audio track’s ⋯ menu).
Choose the Track, and whether to Count in for three seconds.
Press Record and allow the microphone if your browser asks. The edit plays while you speak.
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.
