Instructions for building on Windows are here: http://wiki.audacityteam.org/wiki/Developing_On_Windows
Be warned, building software from the source code on Windows may be difficult. (I use Linux so I'll not be much help other than pointing you to the right documentation)

The tricky thing seems to be finding a small mixer that has 3 or more microphone inputs. The Behringer XENYX 1204USB has 4 mic inputs, but may be a bit too big. You could use a "mini mixer" (example: http://www.amazon.co.uk/Lynx-LMX4-4-Channel-Micro-Microphone/dp/B002SGSMWW) but I'd not ex...

Actually, the issue of slowness with lots of labels appears to be specific to Audacity on Linux. Audacity on Windows is reported to work OK with 1024 labels - I don't know if anyone has tried more than that. The problem with the maximum size of a project that can be saved still remains. This is list...
