[QLab] Audacity update

[Christopher Ashworth]

Audacity beta version 1.3.2 came out last night.

If you go to the preferences you can select File Formats-->When  
Exporting Tracks-->Use Advanced Mixing Options.  This will allow you  
to save multi-channel WAV files.

It supports up to 32 channels when exporting, and allows you to  
quickly patch which channels in the original file will go to which  
channels in the final file.  I just ran a quick test and it seems to  
work nicely.

Have fun,
Chris
