ACID to WAV conversion

I think you can just select them all and do "bounce to clips"? If you need to export them for some reason you could grab the bounced clips from the project audio folder. 
 
Or in case you didn't know you can export as many tracks as you want in one go by selecting "tracks" as source category when you export. Provided you have selected everything you want to bounce (as per usual in Sonar). 
 
FWIW I would be surprised if using ACIDized files increased the saving time by that much, do keep us updated. 
 

I also believe that Sander has a good point (at least) if you are using many clips per track.

I gather that the point of the exercise is to convert the ACID files to plain WAV within the context of the existing project, not necessarily to export the tracks. So bounce to clips seems fastest to me. 

If bouncing to clips does convert acid files to .wav, you have a very good point (I just do not know). 

Bounce to clips doesn't take into account the track volume fader. Only clip gain and fx (and mute status). Unless you have gain envelopes or fx on the clips (not the tracks) the gain shouldn't change at all. Not sure what's up there. 

Similar has come up in the past where another DAW defaults to an export that causes grief internal to others. Does BIAB have an export option for "Broadcast wav" files (or even standard wavs)? Broadcast wavs contain the timing information, so can be imported to their time stamp (requires a SONAR preference checkbox enabled). Checking the export options within BIAB is something to consider (either Broadcast wav, or standard wav gives you something that any other program would recognize).
