This feature allows you to keep audio recordings for later playback. Recordings are only made when NMEA/AIS data is also being recorded.
Audio recordings are stored in separate files and locations than for the NMEA/AIS data. The retention for audio data is handled differently than the NMEA/AIS data. This is done because the audio data is typically much larger than the corresponding NMEA/AIS data. The audio files for the NMEA/AIS data do not necessarily match on file-by-file basis. If you wish to export NMEA/AIS data and audio recordings, be sure to copy both sets of files.
Before using this, be sure to test your audio by using the Test button in the Diagnostics section. This will record 5 seconds of audio and play it back to you. You will be able to evaluate the quality of the audio and get a rough estimation of the data usage per hour. If you find a problem with your device, please report it to us.
Recording audio may significantly affect battery life for mobile devices. The exact effect depends on the specifics of your device.
The quality of recordings and range of recorded sound is dependent on that of your microphone, recording format, and other aspects of your device.
The amount of data used for recordings is much higher than for NMEA/AIS data. We recommend enabling the Automatically Erase Old Recordings feature. If this is not enabled, a warning will be shown when audio recordings exceed 5GB in total size.
When exporting NMEA/AIS recordings, audio data is not included in the export because of the data size. It is necessary to separately export the audio recording files. Each platform has its own preferred audio encoding format and may not be supported when copied to other platforms.
