Customize the Advanced Settings to Fit Your Needs

Microphone Sensitivity Change the mic sensitivity (GAIN). Adjust the mic to compensate for background noise, distance, and other environmental factors.
Recording Mode Choose between Continuous Recording or Voice Activated Recording Modes.
File Bitrate The recording bitrate can be compared to the framerate of videos. Lower bitrates mean smaller file sizes but decreased recording quality. Higher bitrates increase recording quality but take up more room on the recorder.
File Format Choose between MP3 and WAV. MP3 files are compressed and take up less room but can mean lower quality. WAV format is uncompressed, meaning a higher quality but larger file size.
File Length Choose how long each recording is. Longer recordings risk losing more recording time if the battery runs out before the recording can be saved.
Recording Timer Set to automatically record for a specific length of time each day for up to 999 days.
Time & Date Stamp Sync the time and date of the recordings with your computer.
