[CLAM] Help needed to understand how to create an 8 bit u-law wave file

[Xavier Amatriain]

Hi Marty,

Could you send us a bit more code of what you are trying to do? From your
mail I don't quite get it.

All I can say that as for PCM sound formats, all we are doing is to wrap
the great libsndfile library[1]. So, if the format is accepted by
libsndfile it should work in CLAM. Unless you are doing something wrong or
we have a bug ;)
