    Hello All,
    I am relatively new to the whole recording arena and am soaking up as much as I can. I am faced with a new obstacle now - multiband compression.
    I am at the mastering point of production. I have a tightly recorded and mixed song that sounds pretty balanced to me and the people I know with recording experience.
    I want to go the extra mile and make the music that much tighter without compromising my high/low sounds in my music. You get the picture.
    My problem is figuring out what to copress in an overall mix. With individual instruments, compression is a breeze, but when it is all mixed down and in stereo - I am at a loss. Any tips or preferences to further my education of this subject would help tremendously.

    If you have a nice sounding mix to begin with, don't ruin it by throwing a MBC on it.

    Every single track is unique, and there really isn't any particular starting point. Start with a long attack and long release and work from there. Save the MBC for when there's a specific problem that nothing else will fix.

    Why is that you think you need or want to use Multiband compression? Tightness? Sorry, but the true source of tightness comes from the performance, arrangement, blending of tones. Compression is not the be all of making something more tight. True, as a tool compression can help or enhance, but many believe and try to use compression as the fix and it serves as a band aid.

    Multiband compression in the hands of a novice can do more harm than good and you've already mentioned that your still a novice. And if you at this stage already think using compression on instruments is a breeze, I'd very much doubt as well as question your use and results as compression is a really BIG milestone to understand, control and master the use of. Even more so today than 10 years ago as compression is the most mis-understood, overused and abused signal processing step being done in modern recordings.

    Go ahead and play, but just keep your expectations within reason of your skills and experience.

    Compression will most certainly,if used incorrectly, accentuate any serious mistake ... not that ANY mix is a mistake....after all, they're the performance of that moment.,,,,so squeeze the crap out-of-it and if you dont like it be sure that you backed up the last mix....not all Mastered mixes have multi-band compression on them...Its all dependant on your mix as to whether you're gonna need to control a particular range of equalization.....If you try adding it and it suddenly kicks yer ass then its the right thing!

    Purhaps I am asking the wrong question. A better way to put it is how do you choose whether or not to use multiband compression. If in the end you decide to, what would YOU listen for in your own mixes to compress. This is a learning experience and your help is always appreciated. Thanks.

    If you do not know beforehand, why not slap a MBC on it and listen to the result. My experience, amateur level, is that it sometimes makes it sound better. Most of the time worse.

    I would say if you want to, mess with it all you want and use your ear to decide what works and what doesnt.

    I really have no idea what mastering guys do as far as mbc. I use them for lav mics and headsets in a live setting.

    i'm no fulltime mastering engineer, but i've gotten by mastering some DnB records with and without multiband compression.

    everything anyone has said here is pretty much true,,, it's kinda like asking how to use a swiss army knife... well, what are you trying to do with it???

    well,,, someone may scold me for this,,, but here is my thought process on the times i've used one.

    keep in mind, this is AFTER I FEEL THAT THE MIX IS NOT GETTING ANY BETTER, AND I'M SOLELY TRYING TO ENHANCE THE AUDIO.
    here goes:

    1. closely look at a high detailed RTA of the whole song several times

    2. depending on how many bands you have(usually 3 or 4), find the separation frequencies that best serve this song.

    3. squash the whole mix on one band first so you can really hear what the compresser is doing. then you can set a decent attack and release ideal for the groove.

    4. there you can set each band to those att/rel times FOR STARTING OUT,,, then you isolate each band and fine tune the att/rel from there... then you find a close to right threshold/ratio/(knee)/etc? for the band,,,

    5. then you repeat that for each band and get close to what you're after.

    6. look at an RTA while you do this too,,, and constantly compare to the bypassed signal as well.. it's also good to take a song of the same instrument set and tempo if possible and look at it through the same RTA. (there's no perfect way it will look,, but you should be able to tell if something is TERRIBLY different from the average,, you might want to backtrack and correct).

    7. it goes on forever man,,,, constantly compare with other music that's already been through the BS and see what you stuff lacks/ and don't feel discouraged,, cause even the best will tell you they suck compared to ***** ******** ( whoever they think is the best)


    oh yeah,,, and put a big sign over your screen that says "DON'T OVER-DO IT MAN!!!!" jk,, but you don't want to over do it...



    OK,, all you people who know better,, PLEASE SPEAK... cause i'd rather not remain ingorant.. there's a million ways to do anything,, but it's best to know 'em all. :wink:
