What Analog I/O Hardware Can Be Used For Digital Signal Processing On A Laptop Or Desktop Computer ?

While it is entirely possible to use the standard audio interfaces, for audio frequency I/O, I have had great results with the Behringer U-CONTROL UCA202 (http://www.behringer.com/EN/Products/UCA202.aspx).

The UCA202 supports the Windows WDM/KS API and also ASIO although I have found that the WDM/KS interface has provided low enough latency for most of my applications that I have not needed to use ASIO. I have used this interface in a number of applications and also, to great effect, for the laboratory exercises on the Oxford University Digital Signal Processing courses.
