- macOS only — LoopRec uses
AVCaptureSessionand macOS-specific audio APIs. - BlackHole 2ch required — system/meeting audio loopback depends on BlackHole 2ch.
- Technical users — best suited for users comfortable with Audio MIDI Setup and Zoom audio routing configuration.
- Aggregate Device pitfall — using an
Aggregate Deviceas the microphone source is a common cause of echo or double-capture. - AirPods routing — AirPods setups usually require careful
Multi-Output Devicerouting to avoid missing loopback audio or echo. - Recording-first — transcription and summarization are downstream local steps, not built into the app.
- Not notarized — binary distribution is local/ad-hoc signed. You may need to allow it in System Settings → Privacy & Security on first launch.
LoopRec is intentionally focused on a local-first, privacy-first workflow rather than a zero-setup consumer app.
