How would loopautitioneer automatically reed the loop points from within Pd and transfer them?
I can reed the loop points externally with no problem. My problem is to set the loop points automatically from within Pd.

hello all, i don't know if it is relevant, but my simple google search returned this software too:
LoopAuditioneer is a software for evaluating, creating and manipulating loops and cues existing in wav file metadata. It's envisionaged to be useful for sample production for virtual pipe organs, like for instance GrandOrgue software.
SOURCE CODE:
------------
Is available on http://sourceforge.net/projects/loopauditioneer/ by SVN.

libsndfile also can extract loop points from a variety of formats. The relevant code for wav is here https://github.com/erikd/libsndfile/blob/master/src/wav.c#L1140-L1163
