Screen recording with the sound in it

The sound your Mac plays is half the recording — the app's feedback sounds, the video you're reviewing, the other side of the call. macOS's built-in recorder leaves all of it out. ScreenTailor is a native Mac screen recorder with system audio: flip one toggle and the internal sound is captured with the screen, ready to balance in the editor.

Why system audio matters

A demo of a video app that plays silence isn't a demo. A tutorial where the error "ding" is missing loses the moment that mattered. If you've ever exported a recording and realized the sound never made it in, you've hit the gap this feature closes: macOS records your microphone, but not the Mac's own audio — that's why silent screen recordings are so common.

One toggle, no driver

The usual fix is a virtual audio driver (BlackHole, Loopback) plus output routing in Audio MIDI Setup. ScreenTailor skips the whole detour: system audio is captured natively through Apple's ScreenCaptureKit, under the same screen recording permission you've already granted. The speaker toggle sits next to the mic picker in the capture bar and is on by default — record as usual and the sound is just there. The step-by-step is in how to record internal audio on a Mac.

Separate tracks, separate sliders

Your microphone and the system audio are recorded as two independent tracks, not pre-mixed. In the editor, each has its own volume slider: duck the app's music under your narration, boost a quiet call, or mute a track outright — after the recording, no re-take. The balance you hear in the preview is exactly what the exported MP4 gets, and trims and speed changes apply to the audio in sync with the video.

Records even while muted

System audio is captured from the apps before it reaches your speakers. Recording in an office or late at night? Mute the Mac completely — the recording still gets clean, full-volume sound. Headphones, volume down, output switched mid-recording: none of it changes what's captured.

Requirements

• System audio capture: macOS 13 or later (it uses Apple's ScreenCaptureKit).
• ScreenTailor itself runs on macOS 12 and later — on macOS 12, recordings capture screen and microphone.
• No extra permission and nothing to install: the existing screen recording permission covers it.
• Included in the free plan — like every recording feature.

Part of a full editor

The recording lands in ScreenTailor's built-in editor with zoom, captions, effects and Checkpoint Recording — so the clip that has the sound also gets the polish, in one app.
