Recording Does Not Stop

18 comments

I am trying to configure my audio moth. I set a time period via the start and stop times. The moth begins recording at the start time and does not stop. How can I fix this?

 

Attached is an image of two different moths with the same configuration. Both were set with a 2 minute recording period, 1 second of sleep, and 9 seconds record. I should have 12 files. I get one file not even 1 second long and it remains "recording" indefinitely.

 

They act the same way on the default switch just endless recording with no sleep but it only actually records for a fraction of a second.

 

Please Help.

Hi Joe, Do you mind sending a screenshot of you config app settings? Thanks, Andy

Thanks for the quick response I had left my computer right after I sent the last message. Here are the settings I used. I do not have a moth connected in the picture.

What SD cards are you using? It might be that the SD card is corrupting in some way. Could you try reformatting the SD card to FAT32 and trying the schedule again.

Andy,

 

I have tried the following cards:

SanDisk Extreme 32gb

SanDisk Ultra 64gb

SanDisk Ultra 128gb

Patriot 32gb

 

I tried formatting the cards from windows with command line diskpart and also with the guiformat application. I also tried formatting the cards from a mac computer. All were formatted to FAT32.

I am still having the recordings corrupt after fractions of a second.

Do they all corrupt, or just the cards bigger that 32gb?

Aug 24, 2018

yes they all corrupt I tried putting the sample rate all the way down on the 32gb cards as well.

I got it to make the correct amount of files but they are all still cutting off right away.

Has this AudioMoth been working previously?

@Andy I was told so but haven't seen it work myself

Was it purchased through GroupGets?

@Andy I took a working moth and flashed firmware 1.1.0 and it made it start acting as I have stated above. Making me believe these were shipped with a different version firmware from groupgets. Can I get access to some of the old firmware to try. I am trying to find out what funding round we purchased these.

Nevermind I found them on Github, I was having trouble locating them.

@Andy I have solved my problem. It seems one of the links had me download the old firmware inadvertently. This may have not been working with the newest version of the windows application and causing the above issue. Re-flashing the firmware with 1.1.0 fixed the issue. Recording starts and stops as programmed.

 

Thanks for your support.

Hi Joe, Do you know what link was incorrect? The incompatibility is between the configuration app and the firmware. Both need to be up to date, and will work on any AudioMoth hardware. Alex

  • Hi, I have purchased an AudioMoth to detect the ultrasonic sound emitted by bats. And I would like to know how can I detect i) count number of bats ii) bats' flying direction. I am doing a project to contextualize bat data through different actuators of Arduino. Using LEDs, speakers, motors, etc to visualize bat data. For example, if frequency = 45kHz, LED will light up; if more bats, the motor will spin faster, etc. How can I do that? And can I transfer the data live, and wireless, using a raspberry pi and upload it to the cloud? Again, how can I achieve that? Finally, is there any guide to manipulating the bat ultrasonic wav. file to human audible sound or visualize through spectrogram? Any tutorial for that? I am trying to use Adobe Audition. Many Thanks!
  • Hello, we deployed AMs with 64GB cards (formatted to FAT32 with a Mac) and 3 x eneloop 1900mAh AA batteries. Calculated they should last ~8-9 weeks at our recording schedule. Have just found that the first 8 we retrieved all ceased recording within a day of each other, 4 weeks after deployment. The cards only have 19GB of data each, so probably not a card issue. Individual testing of AA batteries pre- and post-deployment showed average voltage of 1.34 each prior, and now each AM had at least one battery with voltage as low as 0.06-0.21V (but others up to 1.14V). Stumped, as a colleague had the same set- up with a slightly longer daily recording schedule and longer deployment, with no issues. Am I right in thinking: 1) there is some critical minimum threshold in battery voltage, below which the AMs won’t work, despite our calculations they should have lasted twice as long? 2) if we decrease the amount of data collected per day they would last longer, and 3) does ticking or unticking the ‘enable low battery cut-off’ box in the configuration app make any difference to this? 4) is there a large error around the mAh drawdown prediction on the app that could explain our predicted vs actual data collection period?
  • Hi, in all my recordings there's a "clicking" noise (26-28kHz). This is an issue that I had before with some recordings but now the noise is louder and it is present in all recordings. The batteries are Energizer AA (new) and the SD card is the SanDisk Extreme 32GB. Is there Anything I can do to make the "clicking" noise disappear?
