that's a good point indeed. i do remember that Mark has aslo referred to
me about the meta-data acid do stuff into wavs, but i'm afraid i've lost
the hint at the bottomless qtractor todo list ;)

question that occurs to me atm. might be: does libsndfile have the means
to read or access that meta-data ?

as said, implicitly, i don't nor ever used acid, but it might be of some
help if someone would hand out one of the acid-stuffed wavs for me to try?

cheers
