Recordings all done in **44.1 KHz, 16 bit format. More often than not, I just download the files on to my PC (currently a Dell Core i7 CPU) and use Ravenlite to search through file for interesting calls. Might seem tedious to some but to me, its kinda enjoyable - almost like going birding but on your computer. Since I am mostly a recreational NFC enthusiast, am not always concerned with total # of flight calls that could be calculated from running the files through the Old Bird Detector programs. Hope to add some photographs here over next few weeks (9/26/11). **cannot say I have found any advantage in terms of quality while recording in 44.1 KHz, 16 bit vs 22.05 KHz, 16 bit.
