Hi! I was wondering if you have made available the design and hardware for the audiomoths v.1.1.0. Also, I would like to know if you have a doc specifying the technical differences and improvements between Audiomoth v.1.0.0 and v.1.1.0 Thanks in advance! And congrats for such a lovely project!
Hello community, i am new to this world, i come from fine arts and in need some advice to take advantage of the Audiomoth. I would like to 1- auto select frequency patterns on the spectrogram for the counting of the call of certain animals on long recordings, not sure what sound editor i can use for this (for example counting the call of the frog 45 times in one hour). 2- I don't understand how i can visualize the full frequency spectrum of a 96 khz or more on a regular audio editor like Audition. It seems that the interface only shows until 44khz. 3- What is the best method to listen to more than 20 khz inaudible sounds ?..pitch /slow down... ? thanks!
1) Does the AM have a resonance, or excess gain at 20kHz? I tried a dozen indoor/outdoor settings, and there is always a band at 20kHz. The spectrum below is inside a quiet room. 2) In most of the indoor, quiet room, recordings, I see a rising thin line in the 30-50kHz range, see the above spectrum, the five panels cover about 20 minutes. Could this be a form of self-noise? 3) The clicking noise, I saw on other posts that this is SD card writing? I only see this occasionally. The image below was from inside a parked car at night - very quiet. Is the suggestion still to get the "Extreme" version of the SD card? Thanks - I love the unit. Keep up the good work - you are making a lot of research possible.
