Configuring Your AudioMoth
Before using the companion app, the AudioMoth needs to be configured so that it has the desired recording settings. This document will go over the different tools available on the configuration app.
Important note: your AudioMoth must be on the most recent firmware in order to be used with the Companion app. If you have not updated your firmware in a while, check out this article that explains how to download the most recent firmware.
Before the AudioMoth can be configured, the AudioMoth Configuration App needs to be downloaded to your computer. It is the first app that appears on the Open Acoustics Devices Desktop Apps page:
Once downloaded, the app will have the following icon:
Open the app and plug the AudioMoth into your computer. Make sure the AudioMoth is switched to the USB/OFF position. Similar to when updating, the green LED on the audio moth should be on and solid, as opposed to blinking when in other modes.
The top of the app displays the time, date, and time zone registered on the AudioMoth. The next box down gives information specific to your AudioMoth: Device ID, Firmware Description, Firmware Version, and Battery Voltage.
The next box, under the Recording Settings tab, allows you to customize the recordings of the AudioMoth. Increasing the Sample rate increases the quality of the audio and the maximum frequency that can be recorded, but for most applications, higher frequencies aren't necessary. Keep in mind higher sample rates will take up more space in the SD card. The Gain changes how strong the audio signal is that is picked up by the AudioMoth. Cyclic recording allows the AudioMoth to sleep for an amount of time and then record in a cycle. This means that when the AudioMoth is scheduled to be recording, it can further be customized to sleep and record at intervals to keep files smaller and save battery.
If you'd like your AudioMoth to record 1 min every 5 mins, you'll want to change it to be Sleep duration: 240 secs and Recording duration: 60 secs. See screenshot below:
The Schedule tab is how you will customize what hours of the day the AudioMoth is gathering audio. The times next to Start recording and End recording can be selected and changed to the specific times that you want the AudioMoth on. To have several recording periods throughout the day, add each period individually. A recording period that is no longer desired can be removed by selecting the corresponding red bar or the period listed on the right side and then clicking the Remove selected period button.
If you want to set up your AudioMoth to continuously record, you'll want to select this as a recording period.
Below that, the dates which the AudioMoth will be recording can be customized by checking the box next to First recording date and Last recording date. Checking the box will turn the text black and then the date can be changed. At the bottom of the page, the number of files, size of files, and energy consumption is estimated.
The Advanced Settings allow you to control what audio you want to be recorded. If you want each deployment of your device to be associated with its own unique deployment ID, you'll want to check on "Always require acoustic time on switching to CUSTOM." This means that Arbimon will be able to differentiate between your deployments. If you do not check this, and you redeploy your device multiple times in the field (after retrieving it and clearing the SD card), it will be recognized in our system as the same deployment.
The filter allows you to choose what frequencies are recorded. The amplitude threshold recording will save space on the SD card if parts of the recordings are expected to be quiet/unwanted. This allows the AudioMoth to only record loud noises (noises above the threshold) along with information about how long the quiet sections of the recording were.

Now that you have all of the desired settings for your AudioMoth, you can press configure AudioMoth. Now you are ready to pair the AudioMoth with the Companion App! Check out this next support article to see how!
