[Stk] Rawwave files... what are they?

[Ariel Elkin]

Speaking of which, it would actually be very useful to be able to easily feed your own impulse responses (e.g. from here: http://www.openairlib.net/) to the STK classes. 

So supporting WAV instead of .raw would be great!

They are used in various synthesis classes, especially the FM classes.  The Mandolin class uses a bunch of the impulse responses to simulate direction dependent sound radiation.  As an STK user, there is likely no reason you would ever want to create your own rawwave files.  In fact, we probably should convert all the rawwave files to a standard “headered" format (WAV or AIF), as we are no longer as concerned with memory limitations as we were in the 1990s.
