If you are on Windows Vista or later, you can use standard 
(non-ASIO) drivers for your sound card and the Windows 
"Nightly Build" ( http://gaclrecords.org.uk/win-nightly/ ).

Select Windows WASAPI as host in Audacity Device Toolbar
then you should have recording latency of about 70 ms or 
a little less. Reduce "Audio to Buffer" in Audacity Recording
Preferences to test if you can reduce latencies a little lower
without the recording failing. 70 ms is a much lower latency 
than you can get with Audacity 2.0.3 release. 

To get recording latency of only 10 ms or less you will still 
have to compile Audacity with ASIO support and then use a
sound card that supports ASIO and install the correct ASIO 
drivers for it as supplied by the sound card manufacturer. 

If you only have a built-in sound device there will probably 
not be any native ASIO drivers for it. In that case you could 
use a "wrapper" driver like ASIO4ALL. However a wrapper 
driver will probably not give you better latencies than the 
70 ms you can get with WASAPI in the Nightly Build. Also to 
use a wrapper driver with Audacity you will have to compile 
Audacity with ASIO support. 

So for absolute best latencies, compile Audacity with ASIO 
support and use a sound card that has ASIO support and 
native ASIO drivers. 

For better latency on Vista and later than you can get with 
Audacity 2.0.3, get the Windows Nightly Build and use the 
Windows WASAPI host, which should work with any sound 
device.
