You can get interfaces capable of recording at 192 khz that should
give you the resolution.
The cheapest I'm aware of is M-Audio Audiophile 192
but Im sure there are plenty of other options.
What I don't know, is if there
is a mic that will go that high.
(A couple of days ago I could have reccomended
posting in the SOS mic forum but there isn't one anymore
Hope this is of some help
