Just barely started. There is just a bare framework showing the things I
have thought of that need to be covered. I have done something on internal
audio bits and something on dual monitors. I think those parts are usable,
the rest are all todo.

That is why I started with internal hardware... There's not that much you
can do to help it, but the things that can be done make the difference
between ok and really bad.

I also only have so much time. I was able to do what I have done so far
off the top of my head. My idea was to have a separate page for each of
the topics covered. Anything on the front page is just intro. Enough to
help you decide which part will help you.

They are welcome to take whatever parts they like. I don't have the time
to take on more responsibility, but I do want to see Ubuntu Studio be more
usable. Maybe with some docs more people will use it and contribute to it.

I'm trying only to give enough to say there are issues. A dynamic stage
mic at 150 ohms may have some what thin sound going into a 1meg input. The
power riding on a mic input would hold the diaphram off center too.
Running into a line input at 10k is less of an issue. Condenser mics
probably wouldn't care as they have an amp to buffer things inside. I use
a little kawai 4 channel mixer. One mic pre and 3 line... but they will
handle guitar straight in (-20 option) The Arts look good too. The thing
is real quick a USB audio interface with pre amp is just as cheap... and

Yup. Most +4 equipment is quiet enough to handle -10 inputs, but internal
mic preamps are not quiet. Those who know anything won't need what I have,
those who don't are probably wondering why their system has so much noise.
Z gets mentioned for those who know to see where I'm going. hopefully it
won't get in the way of the newby.
