I made this as response to this thread on AB forum: https://forum.audiob.us/discussion/20532/advice-needed-compact-audio-recorder#latest
I made it then couldn't upload it because the forum is very restrictive on the file formate. Lucky for me there is Discchord preset sharing that just became available. :P
Obviously the best way to capture sounds in nature or anywhere is to get the mic as close as possible to the source, but that is not alway possible. That is where a eq can help. I simply used a Band Pass filter here, to capture a cicada while keeping background noise down.
