Hello Open Acoustic Developers. I had recommended the purchase of 2 second generation Audiomoths with cases for our not for profit wildlife research group here in Ontario, Canada. WE have as of yet been able to capture any usable audio after a year now. Either the recording contain repetitive mechanical sounding click (that also show up/display in Audio software (Audacity/Sonic Visualizer ) or files having seemingly random file sizes with no discernible audio or files having 0 kb . The most recent contents of the cards are as follows Both units have had been flashed with latest software. I fear they are mechanically defective which is having a serious impact on our research. Can I send them back/shipping is now so incredibly expensive but I dont know what else to do. I truly do NOT believe this is user error and now my fellow researchers are exasperated at this point as the research site is 3 hr drive each way. How can we verify if the hardware is functional/functioning properly... Yes we have tried setting back to defaults but any audio captured is so low in volume/poor quality it is unusable. Would this have anything to do with the cases we purchased with? PLEASE ASSIST AS WE ARE IN REAL NEED OF GETTING THESE RE-DEPOLYED IN A MONTH OR SO. THANK YOU!!! FIRST CARD 2 folders one called ".fsevents" and the other called ".Spotlight-V100 no log file on this card generated Multiple supported cards tried with similar results THE SECOND CARD has following config results Device ID : 247AA501608F8DC4 Firmware : AudioMoth-Firmware-Basic (1.8.0) Time zone : UTC Sample rate (Hz) : 32000 Gain : Low Sleep duration (s) : 5 Recording duration (s) : 3595 Active recording periods : 2 Recording period 1 : 00:00 - 07:00 (UTC) Recording period 2 : 19:00 - 24:00 (UTC) Earliest recording time : ---------- --:--:-- Latest recording time : ---------- --:--:-- Filter : - Trigger type : - Threshold setting : - Minimum trigger duration (s) : - Enable LED : Yes Enable low-voltage cut-off : Yes Enable battery level indication : Yes Always require acoustic chime : No Use daily folder for WAV files : Yes Disable 48Hz DC blocking filter : Yes Enable energy saver mode : No Enable low gain range : Yes Enable magnetic switch : No Enable GPS time setting : No

Hello all, My research organization has 2 new second generation Audiomoths. They have both been flashed with the latest firmware They are running 128 GB high speed quality brand cards with lithium batteries and were to be running 7 hours runs for 13 days and then no files saved but day and time frame folders are created. Any ideas as to what may cause this? Thanks

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!
