Have to admit you make some good points there. Maybe I should call
myself a producer (but it sounds so posh). Still, I don't see why
every sound engineer should have to re-invent the wheel. We should be
able to build on what our pre-decessors have found, if music recording
is to advance.

To make an exaggeration: there's a little trick with the sidechain to
to de-es vocals. Only nobody writes or tells about it, so every new
sound engineer must waste time and find it out for themselves.

Of course, everybody knows this one; I'm just trying to make a point
here that every new sound engineer must virtually start from scratch,
because there's no serious copy on mixing technique, microphone
placement and so. Only shedloads of basic books about homerecording.
And audio colleges are not much better.
