I just had a crazy idea ... Sorry if this is off topic a bit. Does anyone know what frequency ranges bats use? Would a 96KHz 24bit card be able to capture anything useful from their sounds? I was just wondering what it would sound like to get a recording of the bats eating bugs in the evenings in my backyard and then slow it down enough to get into a human audible frequency range. Thanks, Eric Rz. PS just to make this somewhat linux related, if 96KHz is not enough, are there any alsa supported cards that do high enough sample rates?
