ADDITIONAL INFORMATION ! It seems the"AudioMoth USB mic" IS recognised if a SHORT i.e. 1 Metre, micro-USB to USB-C cable with Apple USB-A to USB-c adapter is used !!!!!! But NOT with some longer cables, I have tried 5 metre or 9 metre cables !

Indeed, mine is marked "Model 1632" as well ! Perhaps it is just a mechanical aberration so that the connections don't align or something with this particular pairing ????? If there is going to be a rouge item I WILL GET IT !!! However we do have a functioning alternative so thank you again for your help.

Hi, update ! A new micro-USB to USB-C direct cable connected to iPad works perfectly ! "New micro-USB to USB-A cable" connected to LAPTOP running AudioMoth Live works perfectly as before. "New micro-USB to USB-A cable" connected to IPad via Apple USB-A to USB-C adapter DOES NOT WORK AS BEFORE ! "New micro-USB to USB-a cable" connected via an alternative (unknown manufacturer) USB-A, 3 port hub to USB-C WORKS FINE !!!!!!!!!!!!!!!!!! For some unknown reason my "AudioMoth USB mic" is not recognised by my IPad when connected via the Apple USB-A to USB-C adapter that I have (Supposedly a genuine Apple product purchased from John Lewis) ?????

Hi, indeed I am mystified !!!!! and again yes, I have been perturbed a few times with forgetting to switch to 'CUSTOM' etc ! I will let you know if an alternative extension cable works ???????? Thanks for your, as always, very prompt help and advice !

Hi Alex The AudioMoth USBMic was running the 1.2.4 firmware but is now running the latest 1.3.0 firmware with the same results. HOWEVER !!!!! It seems that the extension cable used for the AudioMoth USB mic (AMUSBM) may be the problem on the iPad with adapter connector ! This extension cable works perfectly fine connecting the AMUSBM to the Laptop and running the AudiioMoth Live App etc !!!! But not it seems when connected to the iPad USB C input with the APPLE adapter ! See below, APPLE USB C to USB adapter (which works fine with the Dodotronic mic, although a different extension cable !) ??? The extension cable wasn't a 'cheap' cable so had thought it should be a 'data cable' as advertised and it seems most of the time IS. I will try an alternative to see if that makes any difference ! For info'. Ultrasonic App not recognising AMUSBM as alternative input device with the same extension cable either !

Thank you Edwin, I will I will give that a try. Cheers

I would like to attach a JrF (Jes Riley French) 'D' Type Hydrophone (cos I have one !) to one of my AudioMoth recorders via the additional 3.5mm jack socket. I understand from JrF that the hydrophones do not need PIP etc., so theoretically should work. The information here seems to suggests that a resistor might need to be added for the system to work ?

Thank You Andy, now it all makes sense !!!!!!!

Have we found any resolution to these odd ticking noises yet ? I have a similar problem with the two new AudioMoths with the new cases. One gives a double tick at about 0.1 sec prf with a slightly stronger syncronised pulse at about 0.5 sec the other gives a single pulse at 0.1 sec ? These are soft admittedly. but very annoying when trying to record/analyse Orthoptera calls when they become obtrusive played back at at 10 X time expansion.

Do we have a local centre for replacement plastic catches ? I have 2 new AudioMoth cases on both of which the hinge areas have failed on the black catch !

Hi Alex Thanks, ah yes that helps my poor brain to make sense of what I'm seeing ! Cheers Martin

Hi Alex Re: Amplitude threshold - forgive me but, why not just have a scale from 0% - 100% that would seem more intuitive to me ? Re: Time zone toggle can could that be useful ? Will look forward to Config App update. Cheers Martin

Sorry I still have no idea what the values mean - if I wanted say to filter Cetacean calls how do I know what value to use ? Martin

Further to above questions - I still do not understand what the numbers associated with "Enable Amplitude Threshold Recordings" actually signify ? How do I know what values to enter ? Plus, It seems one has to tell the Config App to change to UTC+1 every time you start it up. Can this not be a set once until reset function ? Plus, Saving the config does not save the newly entered "Advanced Settings" or the individual "Recording Periods" ? Yours Frustrated

Hi Alex, Thank you very much for this info'. As it happens, about 20 minutes after posting my question I got an email informing me that AudioMoth Round 11 has been announced, it included a reference to the white paper you have so kindly provided !!!!! Had I waited a few minutes I would not have had to disturb you ! Thanks again for your always prompt and helpful replies. Martin

I know this is a rather old thread, but, do we have a different supplier for these VOIR membranes please. I tried Alibaba as the link as above but all I got was bombarded with emails requesting bank details !!!!!

Brilliant ! That fixed it. Not very familiar with cmd.exe etc., so didn't appreciate the error messages properly. However, the screen shot in the AudioMoth Manual doesn't show the "-u" switch, perhaps this needs a look at ? Thanks again for your fantastic support ! Regards Martin

Hi Alex, herewith screenshot as requested ! Hope this helps !

This is a necessary modification ! After testing 1 of my two new Audiomoth units I unrapped the second to deploy them and found that the “sticking out bit” was brocken off !! I don’t know when or how it got brocken but I think this mod would help in preventing this sort of problem ! Martin

Having just received my units and detecting a Pipistrelle on it’s first trial use I would like to reinforce the need for an effective sound triggering system. Martin
