I am in the "No Audiomoth fond" situation and cannot get through. This is what I face:
1. Batteries and SD on, switch USB/OFF, connect to PC and launch Audiomoth-Config
Audiomoth not recognized
No lights
2. Batteries and SD removed, switch USB/OFF, connect to PC and launch Audiomoth Flash App
Audiomoth not recognized
No lights
3. Batteries and SD removed, switch at DEFAULT, connect to PC and launch Audiomoth Flash App
LEDS flashing
Paperclip => LEDS stopped flashing
Paperclip removed
Next menu: No Audiomoth found
After ~10', LEDS flashing again
Anything else to try?

I was about ordering an AudioMoth USB Microphone through
https://groupgets.com/products/audiomoth-usb-microphone-group-order-round-3
but I could only realize the (high) cost of the shipping once I was at the PayPal page, no shipping costs were indicated
in the groupgets cart.
Is there a way for openacousticsdevices to get cheaper shipping to EU? Perhaps to get all EU orders shipped together to the EU and then redistribute them? 42.95 eur for shipping an item that costs 56.95 eur is not reasonable.

I would appreciate advice on the best way to reduce the size of .wav files for archiving using lossless compression.
eg, is AIFF better than FLAC?
I have read this question: A compression tip, and SNR of version1.1 vs. 1.2?
https://www.openacousticdevices.info/support/device-support/a-compression-tip-and-snr-of-version1-1-vs-1-2
but there is no answer to it.
My units are 1.00 and 1.1.0

By some reason, I've got lots of 0 bytes files and some correct wav files: Unit is 24410E085728D5E5 v. 1.0.0 with firmware 1.8.0 SD card (SanDisk Extreme 64Gb U3 A2 XC V30) is far from beeing full. This is the configuration: Device ID : 24410E085728D5E5 Firmware : AudioMoth-Firmware-Basic (1.8.0) Time zone : UTC Sample rate (Hz) : 96000 Gain : Medium Sleep duration (s) : 1500 Recording duration (s) : 300 Active recording periods : 1 Recording period 1 : 04:00 - 20:00 (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 : No Disable 48Hz DC blocking filter : No Enable energy saver mode : No Enable low gain range : No Enable magnetic switch : No Enable GPS time setting : No Any idea on why could this be happening? Are 64Gb SDs not reliable?

Is it possible to change the sd in the field without having to run the configuring app? I mean: 1. switch to USB/off 2. check batteries and replace if needed 3. change SD 4. Back to CUSTOM

My recordings (made with version 1.1 units ) have quite a lot of white noise and would like to compare to those of others (in the 0 - 48 kHz range). As far as I understand from other conversations, this is different than the discrete clicks produced by SD cards. Has anyone made test recordings within a soundproof box with different AUDIOMOTH versions and different recording parameters (I understand different Gain options must have a lot of impact in white self noise)? Is there a guide with advice for deployment (i.e., which Gain use under different circumstances)? Finally, can anyone suggest filters (and software) for reducing noise in post-processing? Thanks, Agus

I set the unit with this configuration and make sure to press Configure Audiomoth: But if I quit the config app, even not removing the unit from the usb, and restart the app, the config app shows a different configuration, which confuses me and makes me doubt on whether the correct configuration has been saved to the unit: Is this "normal"? If it is, no way to get the config app to actually read the correct configuration fro the unit? Agus

In order to download files in the field: Do we need to set the switch to the USB/OFF position before removing the SD? In either case, once the SD is copied and files deleted, and then the SD is inserted back in the unit, is the configuration kept or should we run the configuration app again? In case we change batteries, is the configuration lost? Thanks,

Is there a summary table with the differences among AUDIOMOTH versions 1.0, 1.1 and 1.2? Thanks

My audiomoth unit stopped recording after 3 days only, while 33.8 GB were still free and batteries are reported good with a tester. SD card (FAT32): reported by windows of 57.6 GB; TOSHIBA 64 GB micro 3 XC I Configuration file: https://www.dropbox.com/s/uxt12u4m2gale6n/CONFIG.TXT?dl=0 The first valid file was 27/06/2021 05:05 230.400.488 20210627_050000.WAV Recorded at 21:00:00 24/06/2021 (UTC) by AudioMoth 24410E085728D5E5 at medium gain while battery was 4.8V and temperature was 12.8C. The last valid file was: 24/06/2021 21:05 230.400.488 20210624_210000.WAV Recorded at 05:00:00 27/06/2021 (UTC) by AudioMoth 24410E085728D5E5 at medium gain while battery was 4.3V and temperature was 10.6C. Then I have 5 weird files: 01/01/2098 00:03 488 19700101_000326.WAV 01/01/2098 00:05 196.608 19700101_000457.WAV 01/01/2098 00:05 294.912 19700101_000511.WAV 01/01/1601 02:00 0 19700101_000000.WAV 01/01/2098 00:07 589.824 19700101_000721.WAV all of them with no comment field in the wav header. Was this an SD problem? If so, could we have a list of "certified" SD cards?

The guide does not mention cards > 64 gb. As this is a market that changes at a fast rate (video recording puts a lot of pressure to makers), I wonder if this information is still valid or perhaps there are cards > 64 Gb that could be used (and have been tested) with Audiomoth nowadays. I suggest you clearly note the date in this type of guides.

One of my 1.1.0 units is not found once connected to the USB port (windows). I've been able to upgrade the firmware up to 1.6.0 (I went version by version) using the paperclip, but shortly before the upgrade completes I can hear the sound indicating that the unit has been unmounted. Then it is not mounted anymore, so cannot configure this unit. I have the red light continuously on and the green one flashing. Any way to recover this unit?

Has anyone tested an AudioMoth unit within a soundproof cabin to record its system noise?

Any time I start the config app and connect a unit, it seems as if the previous configuration had been lost. Is there a way to actually check the configuration settings that had been saved to the unit? Also, I feel kind of uneasy by the fact that once I press the "Configure AudioMoth" button, there is no message stating the configuration was actually transferred to the unit. Agus

In Flashing support
Starting from 1.2.1, I can update my Audiomoth 1.1.0 units up to firmware version 1.3.0. Then if I update to 1.4.0 everything seems to go on fine but at the end I get: "No AudioMoth found". Config app does not recognize the unit either. I can flash to 1.3.0 again using the paperclip and then everything works. Note that 1.3.0 supports automatic switching to flashing mode, but I have tried with a paperclip as well. The problem happens with all versions >= 1.4.0 I have to work with 1.3.0

My AudioMoth 1.0.0 worked with firmware 1.2.1 I upgrade to the last 1.4.4 using "Follow instructions to manually switch to flash mode" and everything goes fine. Nevertheless, Once I start AudioMoth-Config 1.3.6, the unit is no longer recognized, despite I get the familiar usb sound at connecting and disconnecting the usb cable. Also, If I start AudioMoth Flah App again, it claims no AudioMoth device is found. Other units 1.0.0 and 1.1.0 with firmware 1.2.1 keep working with AudioMoth-Config 1.3.6, despite the initial message (just do not use the newer features).

Have the units of AudioMoth v1.1.0 (Round 7) been shipped? I have not received those of my order. I inquired in the groupgets page (https://groupgets.com/campaigns/561-audiomoth-v1-1-0-round-7?archived=true#discussion) but got no answer.
Thanks for any information or link, Agus

In Enclosures
The guide (https://github.com/kitzeslab/opensoundscape) states that the enclosure must be "acoustically transparent over the mic". In this regard: 1. When using the provided bag, should we try to get the mic in contact with the plastic? 2. Are all "Ziploc baggies" made of the same material and are actually equivalent in terms of "sound transparency"? 3. Could anyone post which "Ziploc baggies" brands have been successfully used? 4. In general, are there tests on recording quality degradation using the different enclosure alternatives? Should we not have a consensus test of the type "recording an standard sound without any enclosure, with the standard enclosure and with the proposed enclosure"? Cheers! Agus
