Hmm, I chose my format tag "randomly" by adding up some ASCII
values. ;) Looking at the registered companies in mmreg.h
I found not one non-profit organization. Hence I thought I
should not even try registering my OpenACM project with

Erm, so how many ACM codecs for speex are there right now? ;)

One problem with these would be interoperability. If three
different ACM implementations all used the same format tag,
they would most likely not play well with each other.
I have a very specific arrangement in my WAVEFORMATEX header
as well as in the "data" payload of the WAVE file.
