True, log fades would be extremely useful, although I think we need
the linear fades as well.

Implementation should be quite straightforward. You should start from
ecasound/libecasound/linear-envelope.cpp (log-envelope.cpp), and just
rewrite the value() member function. Similarly with the two-stage
envelope.

I don't have time to do this now, but if someone has the time and energy,
just go ahead. I can help integrating the new fades. Anyways, I'll make
this an edi-item so it's not forgotten:
