Obviously, the performance specs for a 24-bit sound card should be 
better than for a 16-bit card.

However, in his review of sound cards for Amateur Radio that appeared 
in the May 2007 QST, Jonathan Taylor, K1RFD wrote that very few 
digital-mode apps are designed to take advantage of the higher 
precision when it is available.

Does anyone know which software apps actually do make use of the 
extra bits and the higher performance of a 24-bit sound card?
