If I store the file as gsm and record it as gsm, open it was gsm 6.10
with Audacity, it is fine.  I know I am doing something wrong with the
u-law conversion.

On a similar note, I have seen in the archives where people have an
output of the file type, showing Hz, bits, etc.. what are they using
for that?
