Screen recording with audio
Your voice and the computer's sound, on separate tracks.
Recording a screen is easy. Recording it with the app's sound and your voice, at levels that work together, is where most tools let you down.

Why this is harder than it should be
On a Mac, the built-in recorder has long captured your microphone but not the sound coming out of the computer; Apple lists system audio recording only for macOS 27 and later. On anything older, a demo of something that makes noise comes out silent unless you install extra audio routing software.
And when both are captured into one track, they are stuck together: if the app was too loud under your voice, you record again.
Both, separately
SmoothCut records the microphone and the system audio as separate tracks, each with its own level, so the balance is something you set afterwards rather than guess at the time.
Then make the voice sound good
Studio voice removes steady background noise with a neural denoiser and levels your voice, on your computer. Silences and filler words can be cut for you, music can sit underneath and dip when you speak, and a voice-over can be recorded later against the picture.
The features that matter here
What does the work
- Studio voice SmoothCut's Studio voice removes steady background noise with a neural denoiser that runs on your computer, then levels and warms your voice. What you hear in the editor is what exports.
- On-device captions SmoothCut turns your voice into word-timed captions with a speech model that runs on your own computer. Download the model once; after that it works offline and nothing is uploaded.
- Auto fix SmoothCut's Auto fix reads a recording and plans the edit: silences, filler words, zooms, layout and sound. You read the plan before it runs, and every step is an ordinary edit you can undo.

Can I change the volume of each after recording?
Yes. The microphone and the system audio are separate tracks with their own levels.
