How do I record with OneMira C1?
Start and stop recordings with the C1 button, understand the rotating top and current LED states, use scheduled capture, monitor battery, and charge daily.
Slow, visible turntable rotation indicates active recording. The OneMira C1 AI Voice Recorder for Meetings – Local Transcription, No Subscription, Notes for ChatGPT & Claude is designed to be physically tactile and effortless to operate. There are no complicated settings, screens, or cloud dependencies — just simple button controls, clear physical status feedback, and native Obsidian-compatible local storage.

How do I start and stop recording?
Managing recordings on the OneMira C1 AI Voice Recorder for Meetings – Local Transcription, No Subscription, Notes for ChatGPT & Claude is completely hardware-tactile. The main interface relies on simple gesture clicks on the Multi-Function Button (MFB) at the center of the device, coupled with the rotating turntable that provides immediate, visual feedback of active recording state.
- Physical start and stop: Press the main button once to start capture and once again to stop. The turntable rotates during active capture and stops when capture ends.
- Audio Specifications: 3 m pickup range. C1 uses dual MEMS microphones with an on-chip neural (RNN) engine and hardware active noise cancellation (ANC) to target near-field human voice frequencies.
- Headphone Capture: To capture the far-end participant audio in online voice calls (e.g. Zoom, Google Meet, Teams) while wearing headphones, macOS 14.2+ is required (using the native Core Audio process tap).
- Separate capture device: C1 records through its own microphones. Optional macOS process-tap capture is a separate desktop feature for online-call audio.
How do scheduled captures work?
You can configure a recurring capture window in Device Settings. Review the selected days and time window before enabling the schedule, and confirm the visible recording signal when capture starts.
Configuring your schedule
- Days: Choose Weekdays Only (Monday through Friday) to avoid capturing weekend personal time, or choose Every Day.
- Time Window: Define the exact hours the device should remain active. Use the quick-select chips (Work, Morning, Afternoon) for fast configuration.
How do I charge and protect the battery?
The C1 integrates a high-capacity rechargeable battery for reliable all-week operations, coupled with offline data safeguards to prevent audio corruption or lost data.
- Specifications: 1250 mAh battery capacity. Operating time: Up to 30 hrs recording · 60 days standby.
- Interrupted-power recovery: Encrypted slices are written transactionally so a restart can resume from the last confirmed position without treating an unconfirmed slice as transferred.
- USB Charging: Supports USB-C 5V⎓1A · ~2 hrs. A full charge from empty to 100% takes approximately 2 hours.
- Precedence Rules: If active recording is initiated while the USB charging cable is connected, the solid white active recording indicator takes precedence over the solid red charging indicator.
