Hi Cuong,
yes, there are some bugs in the code, and other people have similar problems.
David.

Hi David
Downloaded and tried but I can't record. When I choose Windows WASAPI from the
Audio host and record, this dialog appears
Error while opening sound device. Please check the output device
This might be a bug from the alfa version

Hi Cuong,
just to add that some people have found that although wasapi has a lower
latency, the latency varies. If this is the case on your computer then it won't
be a useful option.

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.
