AudioMoth Configuration App 1.3.0 & Firmware 1.4.0

A new version of the configuration app and AudioMoth firmware is now available. This is a big update which adds a number of features which have been sought after by users for a while. These include high/low/band-pass filters on recordings, the ability to disable the duty cycle, temperature measurement and more.

Make sure you're using the latest version before making a post in the support forum, as the issue you're having may have been fixed in a subsequent update.

Update notes

In order to use the new features added in the new Configuration App, you'll need to update your AudioMoth firmware to the latest version (1.4.0).

I'm wondering too if I could change the 32 kb segment size into longer? This to avoid silent gaps between consecutive signals of the same individual (of noctule for instance). Any chance I can change by myself the test different solutions?

@jfgodeau The next version of the firmware and configuration app, due in a couple of weeks, allows you to set a minimum trigger period so that at least x seconds are written to SD card after each trigger event. There are also more tools to allow you to expand and split the resulting files.

Quick question: The release notes say "Improved low-voltage cut-off for use with rechargeable batteries."

What has changed? Is it a decrease in the cuttoff voltage threshold? If so whats the new voltage level?

For reference I had been using rechargeables and found I could get continual nighttime recording for 3.7 nights. I'm testing currently to see what difference the Amplitude Threshold and other changes make.

The previous battery voltage measurement used an assumed microcontroller voltage of 3.3V. This works well when the battery is above 3.6V. However as the battery voltage drops, the processor voltage drops, and the battery voltage becomes inaccurate just when you actually need it to be as accurate as possible. In version 1.4.0 we use another microcontroller channel to measure the internal voltage and then measure the battery using this measured reference. This makes the voltage measurement more accurate and is the one that is used in the WAV file headers. We also use this internal voltage measurement as the cut-off voltage and keep making recording until this falls below 2.8V. This gives enough margin to stop make recordings before the voltage gets low enough that writing to the SD card become unreliable (below 2.7V).

Hi Matthew, These would be quite easy to do in custom versions of the firmware. We've also done versions that calculate the sunrise and sunset times from locations and time. So far we've always tried to maintain backwards compatibility so that every version of the configuration app can configure every version of the firmware (although you won't always get the more advanced features), but at some point we'll likely drop that constraint which will give us much more flexibility for additions such as you describe. Having different settings for each recording period is another popular request which we've done in custom firmware but really need to break compatibility to support properly in the configuration app. Alex
