Hello fellow users. Our research group is excited to deploy our 2 recently acquired Audiomoths 2.0 into the field for ongoing audio data collection. After having reading through the manual we have a few questions regarding optimal settings based on quarry, deployment time and audio quality. We are trying to capture high quality ambient recordings of a jurisdiction trying to verify the presence of certain terrestrial animals on a specific property. The property is sizable and distant in terms of serviceability of the recorder. We plan on retrieving them once a month to download the audio. The recorders will be on from 8pm to 6am every day. Has anyone determined optimal settings to do this in terms of balance of sound quality,duration of time and file size to accommodate a similar schedule? What memory size would be required for such a deployment? As first time users its hard to gauge and we would like to mitigate mistakes from the start if possible. Thank you very much for any tips/suggestions!

thank you so much!
Thanks very much Alex! Much appreciated
The configuration app will tell you the daily energy consumption and SD card requirements of any configuration. We generally use 64GB Sandisk Extreme cards and the config app shows energy consumption values for this card. Other cards can show quite different consumption. Energy and storage requirements decrease with sample rate, but the quality of the recordings increases with decreasing sample rate (as the oversampling reduces the self-noise). With the settings below, good batteries with 3000mAh capacity, and a 64GB SD card, you would be able to record for about 18 days before the card is filled up. With a larger card, you would deplete the batteries in about 25 days.
