rolled on some crickets out in the middle of the night and the middle of the desert last week. In about a 10 minute clip I think I have 5 seconds without traffic or airplanes overhead.
It was worse on the insects I tried to record during the daytime.
Managed to not record the implosion of Texas Stadium on all of my recorders when that went down (was busted by the cops and had to move and re-set quickly)
Got cell phone interference on some tracks I was recording at a gun shoot a couple of years ago. Now I put the iphone in airplane mode before taking pix of the setup.
I've messed up my own recordings in countless ways with things like
-not hitting record
-preamp too hot
-preamp too soft
-hi pass in
-hi pass out
-talking or otherwise making noise
somehow I still get lots of good stuff, but man do I make it hard on myself some days. :)
