Audio Scrubbing — Hear Your Cut While You Scrub
Drag the playhead and hear the audio in real time. Frame-accurate audio scrub, J-K-L transport keys, and jog-wheel feel for finding sync points fast.
What it is and why it matters
Editors who came up on tape spent decades training their ears to find an edit point by sound. Modern editors expect the same: drag the playhead and hear the audio at scrub speed so you can land on the exact moment the door slams, the singer breathes in, the dog barks, or the speaker hits a hard consonant. Skrrol AI's audio scrubbing reproduces that workflow in the browser. Pull the playhead with the mouse or touchpad and the audio plays at the speed you scrub, time-stretched without pitch artifacts so it stays recognizable. Drop the playhead and the scrub stops cleanly — no clicks, no popping.
The scrub ties into the same J-K-L transport keys the rest of the editing world uses. J reverses, L plays forward, K stops, and pressing J or L multiple times accelerates speed by one stop. Audio follows the same speed control, so you can ear-search through a long take at 2x or 4x and still hear what's there. Combined with the frame-accurate playhead, audio scrub turns a tedious task — finding the exact downbeat to align a cut — into a one-handed five-second job. It also pairs with the multi-track timeline so you can solo a single track during a scrub if your scene has a busy mix.
How it works
- 1
Enable audio scrubbing
Press Shift+S to toggle audio scrub mode, or enable it permanently in editor preferences under Playback.
- 2
Drag the playhead
Click and drag the playhead across the timeline. Audio plays at the speed of your drag, time-stretched cleanly.
- 3
Use J-K-L transport
Tap L for play, K for stop, J for reverse. Tap L or J again to double speed; the audio ear-searches with you.
- 4
Solo a track for clarity
If the scene has a busy mix, solo the dialog or music track in the mixer to scrub against just that channel.
- 5
Land your edit point
When you hear the moment you want, drop the playhead, press B for blade, and cut on the frame the audio confirmed.
Benefits
Scrub-speed audio
Audio plays at whatever speed you drag the playhead, time-stretched cleanly with no pitch shift.
J-K-L muscle memory
Industry-standard transport keys with audio that follows the speed — including reverse playback.
Frame-accurate landing
Drop the playhead and it sticks to the exact frame, so your blade cut lands on the audio cue you heard.
Track-soloed scrubbing
Solo a single track in the mixer to scrub against just that source — useful in dense, multi-layered mixes.
Who uses it
Music video editors
Scrub against the music track to find each downbeat and snap your picture cuts to the rhythm.
Podcast video editors
Find breaths, ums, and dead air by ear in seconds rather than scanning the waveform visually.
Documentary editors
Locate exact moments in long interview takes — a sigh, a laugh, a key word — without reading the timecode.
Sound design editors
Place foley, footsteps, and sting effects exactly on the action by scrubbing the picture and audio together.
Dialog editors
Tighten gaps in conversation by ear, removing dead air without crashing the natural cadence of speech.
Frequently asked questions
Does scrub audio sound natural?
Yes. Skrrol uses time-stretching that preserves pitch, so a scrub at 2x speed is recognizable and not chipmunked.
Does it work in reverse?
Yes. Pressing J or scrubbing left plays audio backward at scrub speed.
Will it slow down my computer?
Audio scrub uses the Web Audio API at modest CPU cost. On a typical laptop you won't notice a performance hit.
Can I disable it for silent scrubbing?
Press Shift+S to toggle, or set it off as the default in preferences if you prefer silent scrubbing.
Does it work on touchscreens?
Yes. Drag the playhead with a finger or stylus and the audio plays at touch speed, same as mouse drag.
