System audio and microphone on Mac
On Mac, system audio and your microphone are different paths. FrameCast keeps them separate on purpose: turn the mic on when you want to be in the take.
If a recording has app sound but no narrator, the mic was off — not a broken install.
What each path captures
- System audio — sound from apps and the Mac (the work you are showing)
- Microphone — your voice for narration, captions, and presence
- Camera — picture only; it does not replace mic audio
Typical setups
Silent UI walkthrough: system audio on, mic off.
Teaching take: both on, so viewers hear the product and your explanation.
Captions: mic required so Speech Recognition can hear you.
After the take
Need a polished narrator later? Generate an optional voice-over from transcript segments with account credits — catalogue samples stay free to audition.
Takeaways
- • System audio does not include your voice.
- • Turn the microphone on when narration or captions matter.
- • Voice-over credits are optional and separate from capture.
