Music fade-out
Move the playhead to several second before an audio clip ends. Add a volume pin. Move the playhead to the end of the track and add another pin. Slide the volume down to zero on the second pin to make your audio track fade out.
Precise
Volumecontrol
KineMaster's Volume Envelope lets you add volume pins to an audio clip and drag each pin to the exact level you want. Create smooth fade-ins, fade-outs, dips, and boosts.

What it does
Moment-by-moment audio control
The Mixer gives you a master volume slider that changes an entire clip's level uniformly. Volume Envelope gives you more control.
Mixer: Master Volume Control
One level for the whole clip
Raises or lowers the entire clip's volume uniformly.
Volume Envelope

- Add pins at any point on the audio track
- Use the slider to change each pin to the required volume level
- Smooth change between control points
- Works on video with audio, audio tracks, voiceover, SFX, and extracted audio

Use cases
Three ways creators use Volume Envelope
From fade-outs to ducking and SFX emphasis.
Ducking under voiceover
Add four pins around a voiceover section on a music track. Two close together at the beginning and two close together at the end. Move the second and third volume pins down to 50 (or lower).
SFX emphasis
Temporarily boost a sound effect clip with a short volume peak at the precise moment it should punch through, then return to normal level on either side.
FAQ
Frequently asked questions
Quick answers about Volume Envelope, how it differs from the global slider, and supported audio types.
What is the difference between Volume Envelope and the Mixer volume slider?
The Mixer volume slider raises or lowers the entire clip's level uniformly. Volume Envelope lets you add volume pins at specific moments so you can set different volume levels at different points in time within the same audio track.
What types of audio does Volume Envelope work on?
Volume Envelope works on all audio layer types — background music, voiceover recordings, sound effects, and audio extracted from video clips.
Can I remove or reposition a pin after adding it?
Yes. Tap a pin to select it, then drag it to a new position or delete it. Removing a pin smooths out the volume curve at that point.
Is Volume Envelope non-destructive?
Yes. The envelope is applied as an additional volume effect on top of the original audio and can be removed at any time without affecting the source clip.
