RAW

I believe that the limit is acutally 4G. However, that is not an OS limit, but 
rather a limit resulting from how the file headers are structured.

If thats the case, you should probably bug Kai the main ecasound maintainer
to add support for libsndfile which supports SourceForge's W64 file format
(ie a 64 bit version of a WAV file).
