Usually i apply it on individual tracks that i want to roll off the low end and give more space to the compressor to work better.
I've read some people use it on the main buss. I didn't try that yet and i'd like to know what do you think about that and how in general you use HPF, if you use it at all?
And in case you use HPF, which one is your favorite EQ for the job?
  A friend told me once that the biggest mistake we make is that we believe we live, when in reality we are sleeping in the waiting room of life. |

i think the best are linear phase if you want it transparent. using it on the master i think it s a good idea this way you remove it at the end and let the mastering engineer do it (if he have good full range monitors )
in the mix i use mostly combo of shelving + peaking filter,sometimes hpf + shelving too ,i like it cause it flip the phase so the sound are more together in the mix (sometimes),it can make some tighter cuts than hpf filter too (like cuting with a shelving filter and boost with a peaking filter to add some resonance)

You mean as an effect of just for removing the low end on sounds?
Generally in the mix (ie - when the track is playing) I move the HPF up on sounds until they start to sound artificial/different/bad/limp/hollow then roll back a bit. I believe you should have at least 1 HPF on every sound (except maybe bass) to remove any inaudible or low end artifacts
Since I got my new monitors I am hearing the effect of different brands of filters much better. After a couple years using waves, now I can hear what it's actually doing and I must say - its really boring! Clean I guess..
But I'm starting to use things with more character, I LOVE the Sonalksis compressors, they don't claim to be clean, but the really add something I like to the sound. I'm trying their EQs at the moment but it's a bit early to have an opinion on them yet.
I agree with PoM about Linear on the main bus if you're going to do an enormous sweep effect or something. |

Tomos a eq you can try for color is the free voxengo overtone geq ,i love the sound (but no hpf) and it have m/s processing for more fun  |

i lowcut everything besides of bass-sounds.
on some percussions and hihats my lowcut goes up to realy high frequences around 2-5khz.
besides of that i havent found out that there are that big differences what kind of filter do you use as long as you just cut. the differences comes more if you push something. i prefer the sony stuff and offcourse waves.
about mainbus:
hmmm... dont know what you mean exactly - this is only for deleting deep sub frequences up to 40 hz or something to make the whole bass more clean.

I wouldn't roll off anything at the main bus. Actually, all those FFT equaliziers are changing sounds with high level low energy. Rolling off a whole bus packed with so much low end information in the first place will deffinately not be a way I choose to work on a mix.
I also don't high-pass every channel - only when really needed. Let the sound breathe a little - when it doesn't have that much low end, it also preserves the character it came with.
(Mantik, a highhat wouldn't bring much low end into the mix to judstify high-pass useage, unless you record all your percussion with a boomy mic)
Basicly, an EQ is probably one of the most coloring tools we have at our disposal, and high-pass is the least forgiving setting  Cutting the meat....

not necessarily true...
i think its common mistake
a lot of time the samples you use or the synths already filtered or just playing high notes with no really low freq.. HP those sound will just make your whole production sound thinner.

true as long as we talk about low end. but i realy often even use lowcuts/highpass for deleting mid-frequences especially very often for highhats which bring a lot of mid frequences with them, not to mention percussion loops which are often just to full in the mids to make thim suiteable for song.

You'd be very very surprised then, Phil... an awful lot of hihat samples have lots of energy below 200Hz, right down to DC. I check every sound I use on a very accurate spectrum analyser before I high-pass it, and I only use HPF when I need to... and I have to HP all my hi-hats. Don't let the loudness of the high-frequency content mask the fact that there's lows in there too, which you may not want.

EVERY sound except for basses and kicks (and an occasional lead with bass ambitions) goes straight thru a <80hz HP filter of -90dB in my songs and it works great!

hmmm...-90dB?

This threat is ridiculously methodical.
I highpass if i HEAR low freqs i do not want.
A lot of times leaving some lowend to interact with the kick and bass can actually be quite nice. I hate mixes where everything is totally isolatet and thin just like 90% of all psy today.

But when you have 90+ tracks (granted they don't all play at the same time) frequency overlaps build up, even if you can't hear it. Its good to remove the unnecessary bits.
I don't know about thin, but isolation between sounds is a matter of taste surely?
PoM - thanks for the EQ tip, I'll check it out |

try routing all your percussion through to a group channel and A/Bing it with a high-pass EQ. to be honest i tend to think of it as a lovely glue which can meld everything together. it's not really about thin-ness as about perception; somehow, high-passed hihats (for example) just sit better in the mix, imho. |
