Another free advanced multitrack recording SW "REAPER v.999".
http://www.cockos.com/reaper/download-old-0x.php
Newer versions are not free.
For me it seems to be much more advanced than Audacity and Kristal Audio Engine.
It handles most media formats as wav, mp3, midi, etc.
It supports ASIO 2 drivers
VST, DX and DXi plugins are also supported.
The VST handling in Reaper is excellent. Easy to "connect" plug-ins on tracks (pre, and post recording and pre or post fader) and you see the "instrument panel" of the plug-in with all function buttons etc.
And Reaper has a very good "library" function to show all VST(I)and DX(I) plug-ins that it finds on PC harddisk
