Not if you can see the levels before you export. Then it's just a matter 
of setting the session markers and exporting the session.

Create a mix, set the levels as well as possible with your ears and the 
various meters and gain envelopes. Export the session.


If Ardour generated a peak file for the master track then you wouldn't 
need to export/record the session more than once because you would be 
able to instantly see where the levels were out and you wouldn't need to 
listen to the entire mix every time you wanted to check the overall 
volume flow of the soundscape.

It would basically enable a much faster work flow. When mixing you 
already know what the samples sound like so it's usually just a matter 
of making sure the levels are correct and the fade/transitions are smooth.

This is a part of what a DJ does when cueing a track. By automating the 
process of generating the peak file we allow the producer to spend more 
time on the transitions and fades and less time on the overall levels of 
the mix.

I'm certainly happy to donate time or money or both to this feature if 
it is implemented. I'm sure others will find it just as useful.

The question is how much time and how much money will we need to donate 
to get it done? I'm not sure how much work it will be.
