I`m doing a an increasing amount of mastering, and one of the most frequently occuring problems in dance music (techno in particular) is compression.
Do you always wack compression over your master outs?
Why?
Is it just to make your tune louder?
If that is the case don`t do it!!!
Especially if you intend for your music to be placed on vinyl.
All your doing is sacrificing headroom and dynamics for apparent loudness.
and the final "loudness" of your tune bears little relation to how loud it will be on vinyl after the mastering cut.
Only use mastering compression if you REALLY understand compression, because you are going to make things very difficult for the mastering or cutting engineer if you don`t, and may end up with a flat, squashed, thin sounding record.
And for gods sake, if you don`t really understand compression at the mastering stage too well, then don`t for any reason use MultiBand compression.
This is a very specialised form of compression, and is generally only used for very specific surgical tasks.
Try to leave your final mixdown with a good 3db of headroom (or cushioning) from peak level to 0db if you can.
Yes your tune will apparently sound quiter (ever heard of a volume knob?), but the spared dynamic headroom will leave more room for play for the cutting engineer or mastering stage, and will leave a far better sounding audio piece.
The same can apply for EQ and any other effect you place over the master.
If you are applying the same effects over the master channels of all your tunes (and applying similar settings each time) then you are effectively putting a standardised template over all your music (which from tune to tune will not be standardised, and will require different or NO application of mastering techniques each time).
THIS IS VERY BAD PRACTICE!!!!
Think before you apply mastering effects.
then think again.
Do you REALLY understand what you are doing?
