Hi, This is specifically for the team who worked out in Belize. I am doing a similar project in Costa Rica and will be using the information I collect on spider monkeys to correlate this to gunshots. I would be interested to learn more about your work out there? have you published? If not is it possible to see your reports and to know more about your analysis of the gun shots, your algorithms.....Potentially I do not need to create a training database since you may already have one if you are happy to share this? Best wishes. Jenna
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.
