Audio Recording

Audio recording saves the current mixed audio output to an external USB storage device.

🚨 Before Recording

- Connect a supported USB storage device before recording.
- Make sure the computer has recognized Ystreamer before starting recording.
- If no USB storage device is connected, pressing the Record button causes the indicator to flash rapidly three times and remains blue.
- Connect USB-A storage devices using an OTG adapter.

1. Press the Record button. The indicator turns red and recording starts.
2. Press the button again. The indicator turns blue and recording stops.

• If recording is started or stopped from the device, the recording status in the TAO APP may not update immediately. Refresh the page if needed.

3. The recording is saved automatically.

• Audio files are saved in the Audio folder in the root directory of the storage device. A new subfolder is created automatically each day.
• Audio is recorded at approximately 1.5 Mbps (about 663 MB per hour).
• Recording files are split automatically when they reach 3.7 GB. Recording stops automatically when the storage device is full.

📢  Notes

- Supports FAT32 and exFAT. NTFS is not supported.
- External hard drives require an independent power supply for stable recording. 
- Wait a few moments after recording stops before disconnecting the storage device. Removing it too early may corrupt the recording. 
- If the device is not synchronized with an NTP server, recorded timestamps may be inaccurate.
