Original
Blackbox
Records your calls. Starts by itself. Files stay on your Mac.
You join a call. Blackbox notices and starts recording. You hang up. It stops and saves an M4A. It works with Zoom, Meet, Teams, Discord, FaceTime, Telegram and any other app that uses your microphone.
- No bot, no extension, no account. Nothing joins your meeting. Nothing leaves your Mac unless you ask for a transcript.
- Both sides, on separate tracks. System audio and your microphone are captured by independent pipelines, so one failing never loses the other. Echo is removed from the mic track on-device.
- Built to not lose a recording. Microphone swaps, dropped buffers and app crashes are detected and repaired while the call is still running.
- Optional transcription. Add a Soniox API key in Settings and one click transcribes a finished recording. Without a key, no audio leaves your Mac.

Acknowledgments
Blackbox's ScreenCaptureKit audio capture architecture was informed by studying Azayaka by Martin Persson - a clean, well-built macOS screen and audio recorder. Azayaka's approach to dual-track recording and its PCM buffer conversion patterns (based on Apple's ScreenCaptureKit documentation and this gist by aibo-cora) were valuable references during development.
