I realize that this forum is dedicated mostly to audible sound, however, I need expert advice on recording technique and equipment. I figure this is the place to go. I am a graduate student and for my dissertation research I will be recording the echolocation calls of bats. This not something new, many researchers record echolocation calls and analyze them. This is how it works: The calls for the species of bat that I work with are a single call that sweeps from about 20kHz to 80kHz in a matter of miliseconds. A bat detector is used to slow down the call and then the call is recorded on digital audio tape... typically. From the tape, the call is then downloaded onto a computer and there is software for sound analysis. This is what I am wondering: is there technology that would allow me to skip over the digital audio tape? Is there some form of digital recorded that could save the call as a wav file or something? What kind of a sampling rate to these digital recorders have? Then, I will also need to playback some of these calls. I have been looking for loudspeakers which produce ultrasonic sounds, but I can't seem to find one which does not taper off in intensity at very high frequencies (100kHz). Any suggestions?
Any advice, suggestions, etc... would be greatly appreciated. Thanks!
