This is incorrect. The codings are not compatible and there will be 
information loss when doing alaw-ulaw-alaw or the other way around. Read 
the nots attached to the bug report from me and Mark. 

The fact that there is a computationally cheap way of doing it does not 
mean that there will not be code aliasing effects. Which there are.
