Further to Jim Nollman's email about using a laptop / sound card to make field recordings: While this is my own preferred method, anyone hoping to sample at 96 kHz to record up to 48 kHz should be extremely careful about the sound card they buy. Several seem to have a low pass filter at around 22 or 24 kHz whatever sample rate you run them at, so you don't benefit at all from the higher sampling rate. Low frequency response may also be a serious issue since most cards are designed purely to capture audible sounds. Low pass filtering at around 22 kHz is definitely the case with the Sound Blaster Extigy and the Edirol UA-20 (USB devices). The M-audio delta 44 (PCI interface so no good in laptops) is OK. I've not tested any others, but if anyone has found a USB sound card which will genuinely record to 48 kHz at 96 kHz sampling, I'd be interested to know. Happy recording, Douglas Gillespie [EMAIL PROTECTED] www.ifaw.org/sotw
