Hello Julien,
I also agree, that overcompression is not what
we need. Although, there
are times, where you might want to use it as a tool for sound shaping.
Not everything is classical and live sounding music. Mixture of electro
and acoustic can be in need or just production of one instrument. I
admit, that as a mastering tool, all I use is a limiter at present.
Mostly it works out, sometimes it doesn't.
When considering music produced by people on this list it would
be true that in almost all cases the one doing the mixing and
the one doing the mastering is one and the same person. And this
changes the picture.
Mastering as a separate step has two, maybe three functions or
merits:
1. To adapt the recording to the limits of the distribution
medium. In the days of vinyl records that was essential. Today
this requirement just doesn't exits.
Well, I thought that too at first, but it does actually.
The usable dynamic range of iPod earbuds on a noisy city street is pretty damn narrow, for
instance. Likewise, the dynamic and frequency range of shitty laptop speakers is pretty
narrow too.
I had the experience last year of trying to mix a record so that it would at least be
intelligible on those distribution media. I resisted the pressure to compress the hell out
of the mix, because I hate that sound, it gives me a headache. But if I were really
serious about making those mixes work on those media, I'd have to have squashed them a
lot more than I did.
It was kind of sad for me to walk around with those mixes on shuffle while walking down
the street or riding on BART trains, and realize that the songs we worked so hard to
record were largely below the noise floor in that environment. Commercially-mastered
recordings were noticeably louder and listenable, in the same environment.
2. To provide an extra set of ears and a second reproduction
environment. This won't happen if the mixing and mastering
is done by the same person, within a short time, and using
the same studio.
If what I've read and seen about comb-filtering is true, I'd guess that the
mastering engineer's ROOM, dampening, and speakers are really what you're paying
for as much as his or her ears or engineering knowledge or "vintage" gear.
3. To equalise levels and atmosphere and create
dramatic effect
when assembling an album consisting of several separate pieces.
The is the only function that remains today, in the circumstances
we are talking about.
So, if during mastering you are not satisfied with the sound
why on earth would you try to adjust it using complex filtering
and dynamics on the mixed signal ? Just fix it in the mix, where
you have vastly more possibilities by working on separate tracks.
Digital production techniques make it easy to do this - there
is no need to adhere to a workflow dictated by the state of
technology 30 years ago.
And, I suspect, some of what mastering engineers get paid to do nowadays is use various
tricks to to fix broken home-studio mixes from people who didn't know what they were
doing.
