I posted on this board a while back about what equipment to use to locate a singing bird within a microphone array. I purchased stand alone units from wildlifeacoustics.com to do everything I need (omnidirectional mics, gps for time syncing, and sd card for .wav file storage). We are going to have a total of 6 microphones. Can anyone direct me to a site or paper that can help me take the information from .wav files and locate the birds? Also, if I stagger the height of the microphones off the ground, can I locate the elevation of the bird as well?
