LoopAuditioneer writes from time to time (not always!) chunks into the WAV file, which are probably not required for use in organ sampler software. I am talking about the "fact", "list", and "peak" chunks. The "peak" chunk even does not seem to be part of the WAV file format definition: https://sites.google.com/site/musicgapi/technical-documents/wav-file-format#list

The file 036-C.wav is the original file, which contains already some pitch information. After writing FFT pitch information into this file with LoopAuditioneer (036-C-LA.wav), the three aforementioned chunks appear. I have tools, which do not like these additional chunks an drop error messages.

Is this a bug or are these chunks used by any sampler software?

    All file I/O operations of LoopAuditioneer happen via libsndfile. Of the mentioned chunks the only one that LA sometimes intentionally writes is the LIST INFO. How the other chunks get there I don't know...
