Of course there is no aliasing problem at sampling at 96K and having the frequency go up to 40K. There is an aliasing problem if you then downconvert that to 48K or 44.1K but surely the downconverter should handle that not the soundcard. Mind you why you want more than 22K I have no idea. For sound sources, that is all that you can hear. (NOt me, my ears are old and have trouble with 10K, but if you have little children they might appreciate the extra few KHz, but probably not since they already have to tune out that annoying 15.7KHz scream from the TV. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
